Enabler sind technische Sachen, die man zur Implementierung on fachlichen Aufgaben braucht.

z.B. refactoring eines Software Paketes, before man ein neues fachliches Modul implementiert.
Was sind functional / technical spikes?
Spikes sind Aufgaben,
die mit einer max. Zeit bewertet sind. Sie sind fertig, wenn die Zeit abgelaufen ist.

Im Gegensatz zu Stories, die mit Punkten bewertet sind und fertig sind, wenn sie fertig sind.

Spikes nimmt man, um Ungewisse Aufgaben schon einmal anzuengen, ohne die Planung durcheinander zu schmeissen.

Ist eine Aufgabe ungewiss, so sondiert man diese im vorherigen PI mit Spikes vor.

Functional / Technical sagt nur was ueber das Thema. Func. also fachlich. Technical, also ENabler.
Was sind Stretch Objects?
Ungewisse Aufgaben, auf die auch Zeit eingeplant wird,
auf die sich das Team aber nicht kommittet. (man verspricht sie noh niemandem). Sowas bereitet man mit Spikes vor.

Agile Architecture
Agile architecture is a set of values and practices that support the active evolution of the design and
architecture of a system, concurrent with the implementation of new business functionality. With this
approach, the architecture of a system, even a large one, evolves over time while simultaneously
supporting the needs of current users. This avoids Big Up-Front Design (BUFD) and the starting and
stopping of stage-gated methods.
Agile Release Train
The Agile Release Train is a long-lived team of Agile Teams, typically consisting of 50 - 125 individuals.
The ART aligns teams to a common mission and provides for a regular cadence for planning,
development, and retrospective. Trains provide continuous product development flow and each train
has the dedicated resources necessary to continuously define, build, and test valuable and evaluateable
capabilities every two weeks.
Agile Teams
The Agile Team is a cross-functional group of five to nine individuals who have the ability and
authority to define, build, and test solution value—all in a short-iteration timebox. The team includes
the individuals necessary to successfully deliver this value, supported by specialists where applicable.
Architectural Runway
Architectural runway provides one of the means by which SAFe implements the concepts of Agile
architecture. This runway provides the necessary technical basis for developing business initiatives
and implementing new features and capabilities. An architectural runway exists when the enterprise's
platforms have sufficient existing technological infrastructure to support the implementation of the
highest-priority, near-term features without excessive, delay-inducing redesign.
Budgets
SAFe provides strategies for Lean-Agile budgeting that funds value streams instead of projects. This
empowers value streams with their own dedicated budget for rapid decision-making and flexible
value delivery, while Program Portfolio Management (PPM) retains control of total spending, which is
adjusted over time.
Built-in Quality
Built-in quality is one of the four core values of SAFe. The enterprise's ability to deliver new
functionality with the fastest sustainable lead time, along with the ability to be able to react to rapidly
changing business conditions, is dependent on built-in quality.
Business Owners
Business Owners are a small group of stakeholders (typically three to five) who have the ultimate
fiduciary, governance, efficacy, and ROI responsibility for the value delivered by a specific release
train. Business Owners typically have management responsibility for Customer relationships,
development, solution quality, deployment, operations, Product Management, and architecture.
Capability
Capabilities are similar to features
however, they account for higher-level behaviors of the solution,
which often spans multiple ARTs. Capabilities are maintained in the value stream backlog and are
sized to fit in a program increment, so that each PI delivers solution value.
...
CapEx and OpEx
A value stream budget may include both CapEx and OpEx elements. CapEx typically captures the
expenses required to purchase, upgrade, or fix tangible physical assets or other property used to
support solution building. In some cases, CapEx may also capture elements of the costs of labor for
development of certain intangible assets. OpEx costs typically include salaries and overhead, contract
labor, materials, supplies, and other items directly related to solution development activities.
Communities of Practice
A Community of Practice (CoP) is an informal group of team members and other experts, acting
within the context of a program or enterprise, that has a mission of sharing practical knowledge in
one or more relevant domains.
Continuous Integration
Continuous integration is a practice whereby team members integrate and validate their work
frequently
in the case of software, this can occur at least daily or even multiple times per day. Where
possible, integration is verified by automated build and test environments that quickly identify
integration problems and defects.
...
Coordination
See Value Stream Coordination.
Core Values
SAFe respects and reflects four core values: alignment, built-in quality, transparency, and program
execution.
Customer
The Customer is whoever consumes the work of a value stream. They are the ultimate arbiters of
value delivered. Whether internal or external to the development organization, they are an integral
part of the development value stream.
Develop on Cadence
Basing routine development activities on a fast, synchronous cadence—a regular, predictive rhythm
of important events—helps manage the inherent variability in systems development. This is a
fundamental premise of SAFe. Its effects can be seen directly on the Big Picture, with the fast
cadence of synchronized, short iterations followed by the further integration of those iterations into
larger program increments.
DevOps
DevOps is a mindset, culture, and set of technical practices that stresses communication,
collaboration, and close cooperation between Agile development teams and other technology
professionals who are necessary for developing, testing, deploying, and maintaining software and
systems.
Economic Framework
An economic framework is a set of decision rules that aligns everyone to the financial objectives of
the mission, including budget considerations driven from the program portfolio. SAFe's first Lean-
Agile principle is to take an economic view
the economic framework captures the essential economic
elements for successful solution development.
...
Enabler Capability
Enabler capabilities occur at the value stream level, where they capture work of that type. As these
enablers are a type of capability, they share the same attributes, including a statement of benefits
and acceptance criteria, and they must be structured so as to fit within a single PI.
Enabler Epic
Enabler epics are a type of epic, and as such are written using the value statement format defined for
epics. They tend to cut across value streams and PIs. They require a lightweight business case to
support their implementation. They are identified and tracked through the portfolio Kanban system.
Enabler Feature
Enabler features occur at the program level, where they capture work of that type. As these enablers
are a type of feature, they share the same attributes, including a statement of benefits and
acceptance criteria, and are structured so as to fit within a single PI.
Enabler Story
Enabler stories, as a type of story, must fit in iterations. However, while they may not require user
voice format, they have acceptance criteria to clarify their requirements and support demonstration
and testing.
Enablers
Enablers encapsulate the exploration and the architectural and infrastructure development activities
necessary to support some future solution capability. They occur at all levels of the framework and
are described as enabler epics, enabler capabilities, enabler features, and enabler stories, depending
on their level.
Enterprise
The enterprise represents the business entity that has the ultimate strategy, fiduciary, and
governance authority for the value streams that constitute a SAFe portfolio. Each SAFe portfolio
exists in the broader enterprise context
that is the source of the business strategy that the portfolio
must address. The enterprise also provides the general governance model for all portfolios.
...
Enterprise Architect
The Enterprise Architect works with business stakeholders and Solution and System Architects to
drive holistic technology implementation across value streams. The Enterprise Architect relies on
continuous feedback, fosters adaptive design and engineering practices, and drives collaboration of
programs and teams around a common technical vision.
Epic
Epics are significant initiatives that help guide value streams toward the larger aim of the portfolio.
They are investment intensive and far ranging in impact. They require a formulation and analysis of
cost, impact, and opportunity in a lightweight business case, as well as financial approval before
implementation. There are two kinds of epics: business epics and enabler epics, and they may
appear at the portfolio, value stream, and program levels.
Epic Owners
Epic Owners have the responsibility of shepherding epics through the portfolio Kanban system. They
develop the business case and, when approved, work directly with the key stakeholders on the
affected trains to help realize the implementation.
Feature
A Feature is a service provided by the system that fulfills stakeholder needs. Each is developed by a
single Agile Release Train. They are maintained in the program backlog and are sized to fit in a
program increment so that each PI delivers conceptual integrity. Each feature includes a statement of
benefits and defined acceptance criteria..
Implementing 123
Implementing SAFe 1-2-3 is a proven, successful pattern for SAFe implementation. It describes three
basic steps: (1) train implementers and Lean-Agile change agents
(2) train all executives, managers,
and leaders
...
(3) train teams and launch Agile Release Trains.
...
Innovation and Planning Iteration
SAFe provides for periodic innovation and planning iterations, which serve a variety of purposes. They
provide an estimating buffer for meeting objectives, a dedicated time for inspect and adapt and PI
Planning activities, a cadence-based opportunity for innovation, time for continuing education, time
for working on the technical infrastructure and other impediments, and time for backlog refinement.
Inspect and Adapt
Inspect and adapt (I&A) is a regular event, held at the end of each PI, that provides time to
demonstrate the solution
get feedback
...
and then reflect, problem solve, and identify improvement
actions. The improvement items can then be immediately incorporated into PI planning.
...
Iteration Execution
In SAFe, iterations have a fixed, two-week timebox. Agile Teams take items from the iteration backlog
and define, build, and test them into the system baseline during this two-week period.
Iteration Goals
Iteration goals are a high-level summary of the business and technical goals that the team and
Product Owner agree to accomplish in an iteration. In SAFe, iteration goals are integral to the
effective coordination of an Agile Release Train as a self-organizing, self-managing team of teams.
Iteration Planning
Iteration planning is the ceremony during which all team members plan the upcoming iteration. The
output of the meeting includes the iteration backlog, consisting of the stories and acceptance criteria
committed to in the iteration
a statement of iteration goals
...
and a commitment by the team to the
work needed to achieve those goals.
...
Iteration Retrospective
The iteration retrospective is a short team meeting held at the end of an iteration, wherein team
members gather in a private, safe environment to discuss the efficacy of their practices and define
improvements for the upcoming period.
Iterations
Iterations (sprints in Scrum) are a strict timebox in which teams deliver incremental value in the form
of working, tested software and systems. Each iteration has a standard pattern: plan the iteration
commit to a goal
...
execute
...
demo the work to the key stakeholders
...
and, finally, hold a retrospective,
wherein the team analyzes and determines actions necessary to improve their performance.
...
Lean-Agile Leaders
Lean-Agile Leaders are lifelong learners, managers, teachers, and coaches who help teams build
better software systems through understanding and exhibiting the values, principles, and practices of
Lean, systems thinking, and Agile software development. Lean-Agile Leaders adhere to the principles
of Lean-Agile leadership.
Lean-Agile Mindset
By applying the Agile Manifesto and Lean thinking, a Lean-Agile mindset provides a comprehensive
approach to Lean-Agile development that focuses on understanding and optimizing the flow of value
from concept to delivery. SAFe's House of Lean is based on delivering value in the sustainably
shortest lead time, respect for people and culture, flow, innovation, and relentless improvement—
supported by a foundation of Lean-Agile leadership.
Metrics
The primary measure in SAFe is the objective measurement of working solutions. This is determined
empirically, by demonstration throughout and at the end of every iteration and program increment.
There are a number of additional intermediate and long-term measures as well, metrics that teams,
programs, and portfolios can use to measure progress.
Milestones
Milestones mark specific progress points on the development timeline, and they can be invaluable in
measuring and monitoring the progress and risk of a program. As opposed to phase-gate milestones,
SAFe milestones are based on PIs, planned learning points, and fixed dates.
Model-Based Systems Engineering
Model-Based Systems Engineering (MBSE) is the application of modeling and modeling tools to the
requirements, design, analysis, and verification activities in solution development. MBSE provides a
cost-effective way to learn about system characteristics prior to and during construction, and it helps
manage the complexity and cost of large-system documentation.
Nonfunctional Requirements
Nonfunctional requirements describe system attributes such as security, reliability, performance,
maintainability, scalability, and usability. They can also be constraints or restrictions on the design of
the system.
PI Planning
PI planning is the seminal, cadence-based, face-to-face planning event that serves as the heartbeat of
the Agile Release Train. It is integral and essential to SAFe.
Portfolio Backlog
The portfolio backlog is the highest-level backlog in SAFe. It provides a holding mechanism for the
upcoming business and enabler epics required to create a portfolio solution set, a set that provides
the competitive differentiation and operational efficiencies necessary to address the strategic themes
and facilitate business success.
Portfolio Business Epic
Portfolio business epics capture the largest cross-cutting, business-facing initiatives that occur within
a portfolio.
Portfolio Kanban
The SAFe portfolio Kanban system is used primarily to identify and manage the flow of epics that
affect the course of action for value streams and the Agile Release Trains (ARTs) that realize them.
Portfolio Level
The SAFe portfolio level is the highest level of concern in SAFe. It provides the basic constructs for
organizing the Lean-Agile enterprise around the flow of value via one or more value streams, each of
which develops the systems and solutions necessary to meet the strategic intent.
Pre and Post-PI Planning
The pre- and post-PI planning meetings allow ARTs and suppliers in large value streams to build an
aligned plan for the next PI. The pre- and post-PI planning meetings serve as a wrapper for program
level PI planning, where the actual, detailed planning takes place.
Product Management
Product Management is responsible for identifying Customer needs. They own the ART vision and
roadmaps, pricing, licensing, ROI, and the program backlog. They drive PI objectives and release
content via prioritized features and acceptance criteria, and they accept features into the baseline.
Product Owner
The Product Owner is the team member responsible for defining stories and prioritizing the team
backlog. The Product Owner is also a member of the extended Product Manager/Product Owner
team, understanding and contributing to the program backlog, vision, and roadmap.
Program Backlog
The program backlog is the single, definitive repository for all the upcoming work anticipated to
advance the Agile Release Train solution. The backlog consists primarily of features intended to
address user needs and deliver business benefits
it also includes the enabler features necessary to
build the architectural runway.
...
Program Epics
Program epics are initiatives that are large enough to warrant analysis and a lightweight business
case, but they are constrained to a single Agile Release Train. Unlike features, which are small enough
to fit inside a single PI, program epics could take several PIs to develop. They can be a result of value
stream or portfolio epics, or they may arise locally as ARTs reason about initiatives that represent
larger effort and value.
Program Increment
A Program Increment (PI) is the larger development timebox that uses cadence and synchronization
to facilitate planning, limit WIP, provide for aggregation of newsworthy value for feedback, and ensure
consistent program level retrospectives. It is composed of multiple development iterations and an
innovation and planning iteration. Due to its scope, the PI also provides the cadence for
consideration of portfolio level considerations and roadmaps.
Program Kanban
The program Kanban helps ensure that features are analyzed prior to reaching an iteration
boundary. They are estimated and prioritized appropriately, and feature acceptance criteria are
established.
Program Level
The program level is where people and other resources are applied to some important, long-lived
enterprise mission. Programs in SAFe are delivered by long-lived Agile Release Trains, which deliver a
portion (in some cases all) of a value stream.
Program PI Objectives
The aggregation of each team's PI objectives becomes the program PI objectives, which are approved
and assigned business value by the Business Owners. If value stream level PI planning is needed,
then the programs' PI objectives are synthesized and aggregated to become value stream PI
objectives.
Program Portfolio Management
Program Portfolio Management (PPM) represents the function that has the highest-level strategy and
fiduciary decision-making responsibility in an enterprise portfolio. The PPM function has
responsibility for strategy and investment funding, program management, and governance.
Release
The goal of Lean-Agile is frequent delivery of valuable, working, and fully tested solution increments.
This is accomplished via a stream of releases, each of which has been validated and approved for
final efficacy of use and is accompanied by the documentation necessary to ensure successful
application.
Release Any Time
SAFe provides a separation of concerns that provides development teams with the cadence and
synchronization tools they need to manage complexity and rapid change in their environment, while
allowing for either synchronous (occurring on the PI boundary) or asynchronous (occurring any time)
releases of value to the market.
Release Management
Release Management is a function that assists with planning, managing, and governing releases. This
function has the authority and responsibility to help guide the value stream toward the business
goals. It may contain dedicated individuals, or it may simply be a role that various Lean-Agile leaders
play in the portfolio.
Release Train Engineer
The Release Train Engineer (RTE) facilitates Agile Release Train processes and execution. The RTE
escalate impediments, helps manage risk, helps ensure value delivery, and drives continuous
improvement.
Roadmap
The roadmap communicates planned Agile Release Train and value stream deliverables and
milestones over a time line. The roadmap includes committed deliverables and visibility into the
forecasted deliverables of the next few PIs. It is developed and updated by solution and product
management as the vision and delivery strategy evolve.
SAFe Principles
SAFe is based on nine immutable, underlying Lean and Agile principles. These are the fundamental
tenets, the basic truths and economic underpinnings that drive the roles and practices that make
SAFe effective.
Scrum Master
The SAFe Scrum Master is a servant leader and coach for the Agile team. Primary responsibilities
include ensuring that the process is being followed
educating the team in Scrum, XP, and SAFe
...
eliminating impediments
...
and fostering the environment for high-performing team dynamics,
continuous flow, and relentless improvement.
...
ScrumXP
ScrumXP is a lightweight yet disciplined and productive process for cross-functional, self-organized
teams to operate within the context of SAFe. A ScrumXP team consists of five to nine people,
collocated wherever possible. ScrumXP teams use Scrum project management practices and XPinspired
technical practices, and they visualize and measure the flow of value.
Set-Based Design
Set-based design is a practice that maintains multiple requirements and design options for a longer
period in the development cycle. Empirical data is used to narrow focus based on the emergent
knowledge.
Shared Services
Shared Services represent specialty roles that are necessary for the success of an Agile Release Train
or value stream but that cannot be dedicated full time to any specific train. These may include
security specialists, information architects, DBAs, technical writers, quality assurance, IT operations
personnel, and more.
Solution
A solution is either a final product delivered to the ultimate economic buyer or, alternately, a set of
systems that enable an operational value stream within the organization.
Uniquely associated to one value stream. Defined by Solution Intent.
Solution Architect/Engineer
SAFe Solution Architect/Engineering represents the individuals and teams who have the technical
responsibility for the overall architectural and engineering design of the solution. They help align the
value stream and Agile Release Trains to a common technological and architectural vision.
Solution Context
Solution context identifies critical aspects of the target solution environment and its impact on the
usage, installation, operation, and support of the solution itself. It impacts development priorities and
infrastructure, test environments, solution capabilities, features, and nonfunctional requirements. It
also establishes focus for DevOps and similar deployment considerations.
Solution Demo
The solution demo is the apex event of the PI cycle for a value stream. The results of all the
development efforts from multiple ARTs—along with the contributions from suppliers—are
integrated, evaluated, and made visible to the Customers and other stakeholders. This demo
provides a regular cadence for objective evaluation of the solution and for gathering stakeholder and
Customer feedback.
Solution Intent
Solution intent represents the repository for storing, managing, and communicating knowledge of
the solution that the system builders are developing, as well as technical information about how they
are going to build it. It includes specifications, designs, and tests for the current state of the solution,
as well intended changes. It can be realized in many forms, from documents, spreadsheets, and
whiteboard sessions to formal requirements and modeling tools.
Solution Management
Solution Management is the value stream content authority. They have primary responsibility for
development and prioritization of the value stream backlog. They work with Customers to
understand their needs, create the vision and roadmap, define requirements, and guide work
through the value stream Kanban.
Spanning Palette
The spanning palette is not an artifact per se
rather, it comprises various roles and artifacts that may
be applicable at any level of the framework. It is used to customize the framework implementation to
a specific context. For a more complete discussion, see Program Level.
...
Stories
Stories are the primary artifact used to define system behavior in Agile development. Stories are not
requirements
they are short, simple descriptions of a small piece of desired functionality, usually told
from the user's perspective and written in the user's language. Each story is intended to support
implementation of a small, vertical slice of system functionality, supporting highly incremental
development.
...
Strategic Themes
Strategic themes are specific, itemized business objectives that connect the SAFe portfolio to the
enterprise business strategy. They provide business context for decision-making within the portfolio,
affecting the economic framework and investments in value streams and ARTs. They serve as inputs
to the budget, portfolio, solution, and program backlog decisions.
Supplier
Suppliers develop and deliver components and subsystems that help Lean-Agile organizations deliver
value to their Customers. Suppliers possess unique and distinctively competent skills and solutions
and are experts in their technology
they can provide a high leverage point for fast and economical
delivery.
...
System Architect/Engineering
System Architect/Engineering aligns the ARTs to a common technological and architectural vision of
the solution under development. They participate in defining the system and subsystems, validate
technology assumptions, and evaluate alternatives. They support system development through
providing, communicating, and evolving the larger technological and architectural view of the
solution.
System Demo
The system demo is a primary mechanism for evaluating the full ART system and gaining feedback
from the stakeholders. It occurs at the end of every iteration and provides an integrated, aggregate
view of the new features that have been delivered by all the teams on the train in the most recent
iteration. It provides the ART with a fact-based measure of current, system-level progress within the
Program Increment.
System Team
The System Team is a special Agile Team on the ART or value stream (sometimes both) that is
chartered to provide assistance in building and using the Agile development environment
infrastructure, including continuous integration and test automation, integrating assets from Agile
Teams, and performing end-to-end solution testing. They often participate in demonstrating
solutions in the system demo.
Team Backlog
The team backlog represents the collection of all the things a team needs to do to advance their
portion of the system. It contains user and enabler stories that originate from the program backlog,
as well as stories that arise locally from the team's specific context.
Team Demo
The team demo is used to measure the team's progress by showing working stories to the Product
Owner and other team members and stakeholders, and to get their feedback at the end of each
iteration. Teams demonstrate every story, spike, refactor, and new nonfunctional requirement in this
demo.
Team Kanban
Team Kanban is a method that facilitates the flow of value by visualizing work flow, establishing workin-
process limits, measuring throughput, and continuously improving the process. Kanban is
particularly useful for System Teams, DevOps, and maintenance teams, and for other situations
where a response mandate, fast-changing priorities, and lower value of planning lead them to this
choice.
Team Level
The team level describes the organization, artifact, role, activities, and process model for the Agile
Teams who power the Agile Release Train.
Team PI Objectives
Team PI objectives are a summarized description of the specific business and technical goals that an
Agile Team intends to achieve in the upcoming PI. Their purpose is to validate understanding of
business and technical intent
focus alignment on outcomes rather than on process or tactical
concerns
...
and summarize data in a way that enhances communication, alignment, and visibility.
...
Test-First
Test-first is the practice of developing and testing a system in small increments, often with the
development of the test itself preceding the development of the code or component. In this way,
tests serve to elaborate and better define the intended system behavior before the system is built,
thereby enhancing quality.
User Experience
While Agile Teams have responsibility for implementing the solution, including the user-facing
elements, User Experience (UX) designers support a consistent user experience across the
components and systems of the larger solution.
Value Stream Backlog
The value stream backlog is the definitive repository for all the upcoming work anticipated to advance
the solution. The backlog consists of upcoming capabilities, which can span multiple ARTs, as well as
enablers that advance learning and build the architectural runway.
Value Stream Coordination
Value stream coordination provides guidance for managing dependencies across value streams in a
portfolio.
Value Stream Engineer
The Value Stream Engineer facilitates value stream processes and execution. He escalates
impediments, manages risk, and helps ensure value delivery and continuous improvement. He is a servant leader. Responsibilities can be compared to RTE
Value Stream Epics
Value stream epics are initiatives that are large enough to warrant analysis and a lightweight business
case (see Epic) but are constrained to a single value stream. Unlike capabilities that are defined to be
small enough to fit inside a single program increment, value stream epics could take several PIs to
develop. They can arise as a result of portfolio epics, or they may arise locally as value streams plan
larger initiatives.
Value Stream Kanban
The value stream Kanban helps ensure that value stream epics and capabilities are reasoned about
and analyzed prior to reaching a PI boundary, that they are prioritized appropriately, and that
acceptance criteria have been established to guide a high-fidelity implementation.
Value Stream Level
The value stream level supports builders of large and complex solutions that typically require
multiple ARTs, as well as the contributions of Suppliers. This level is most often used by enterprises
that face the largest systems challenges, building large-scale, multidisciplinary software and cyberphysical
systems.
Value Stream PI Objectives
During the post-PI planning meeting, ART objectives are further summarized at the value stream level
and become value stream objectives. This is the top level of PI objectives in SAFe, and they
communicate to stakeholders what the value stream, as a whole, will deliver in the upcoming PI.
Value Streams
Value streams are the primary SAFe construct for understanding, organizing, and delivering value.
Each value stream is a long-lived series of steps that an enterprise uses to provide a continuous flow
of value to a Customer. Value streams are realized by Agile Release Trains.
Vision
The Vision describes a future view of the solution to be developed, reflecting Customer and
stakeholders needs as well as features and capabilities that are proposed to address those needs. It
provides the larger, contextual overview and purpose of the solution under development. Vision
appears on the spanning palette and can be applied at any level in the framework.
Weighted Shortest Job First
Weighted Shortest Job First (WSJF) is an economic model for prioritizing "jobs" based on product
development flow. WSJF is calculated as the cost of delay divided by job duration. In SAFe, "jobs" are
the epics, features, and capabilities that are developed by ARTs. There are three primary elements to
the cost of delay: 1) user-business value, 2) time criticality, and 3) risk reduction-opportunity
enablement value.

#4 BUILD INCREMENTALLY WITH FAST, INTEGRATED LEARNING CYCLES
#5 BASE MILESTONES ON OBJECTIVE EVALUATION OF WORKING SYSTEMS
#6 VISUALIZE AND LIMIT WIP, REDUCE BATCH SIZES AND MANAGE QUEUE LENGTHS
#7 APPLY CADENCE, SYNCHRONIZE WITH CROSS-DOMAIN PLANNING
#8 UNLOCK THE INTRINSIC MOTIVATION OF KNOWLEDGE WORKERS
#9 DECENTRALIZE DECISION-MAKING
Principle 1 - TAKE AN ECONOMIC VIEW
(SAFe Lean-Agile Principles)
⸚ deliver early and often
⸚ incremental development and delyverz produces value far earlier
⸚ 5 primary trade-off parameters for product development economics: "development expense", "cycle time", "product cost", "value", "risk"
Principle 2 - APPLY SYSTEMS THINKING
(SAFe Lean-Agile Principles)
⸚ the enterprise who builds the system is a system too (-> system builder need to create environment where ppl can collaborate, suppliers and customers strongly integrated in value streams...)

⸚ only management can change the system (-> exhibit and teach lean, eliminate functional silos, build long term customer relationships...)
Principle 3 - ASSUME VARIABILITY; PRESERVE OPTIONS
(SAFe Lean-Agile Principles)
⸚ leave design options open as long as possible
⸚ multiple design options in the beginning, then eliminate the weaker options over time through continious evaluation of economics and technical trade-offs
Principle 4 - BUILD INCREMENTALLY WITH FAST, INTEGRATED LEARNING CYCLES
(SAFe Lean-Agile Principles)
⸚ avoid the "risk remains in the program until the deadline and even until the use of the system
⸚ customers and systems builder try hard to define the requirements and select "the best" design up-front
⸚ increment of working system as result. this can be evaluated by system builder and customer
⸚ fast learning through fast cycles Pland-Do-Check-Adjust --> the more frequent the faster the learning
Principle 5 - BASE MILESTONES ON OBJECTIVE EVALUATION OF WORKING SYSTEMS

⸚ problem with phase-gate milestones (forcing too early design decisions, centralizing requirements, silos, large batches, late feedback...
⸚ ! base milestones on objective evidence (system is built in increments, integration points that demonstrates..., every milestone involves a portion of: requirements, design, development, testing
Principle 6 - VISUALIZE AND LIMIT WIP, REDUCE BATCH SIZES AND MANAGE QUEUE LENGTHS
(SAFe Lean-Agile Principles)
⸚ make current WIP visible to all stakeholders
⸚ limit WIP to improve focus and avoid task-switching costs. alligne with Dev-capacity
⸚ reduce batch size (those requirem., designs, code, tests and other work items that move through the system) --> faster flow
⸚ reduce queue length decreases delays, reduces waste, increases predictability of outcomes (keep backlogs short and largely uncommitted)
Principle 7 - APPLY CADENCE, SYNCHRONIZE WITH CROSS-DOMAIN PLANNING
(SAFe Lean-Agile Principles)
⸚ cadence (Takt), synchronization and cross-domain planning help to provide
⸚ sufficient uncertainty provides freedom for innovation
⸚ sufficient certainty allows business to operate
Principle 8 - UNLOCK THE INTRINSIC MOTIVATION OF KNOWLEDGE WORKERS
(SAFe Lean-Agile Principles)
