Agile Manifesto

We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: 1. Individuals and interactions over processes and tools 2. Working software over comprehensive documentation 3. Customer collaboration over contract negotiation 4. Responding to change over following a plan That is, while there IS value in the items on the right, we value the items on the left MORE.

Coordination

When a value stream is too big for a single ART, then multiple ARTs are necessary to deliver that value, and they typically have functional, technical, and even personnel dependencies that need to be routinely managed. In this case, delivery of end-user value becomes dependent on synchronization of content management, integration, and releasing.

Program Level

Where funding for personnel and other resources are applied to some important, long-lived, enterprise mission. In the SAFe enterprise, most _______ are a one-for-one relationship with an Agile Release Train, each following the funding, governance and incremental development patterns of the ART to deliver their portion of a Value Stream. In this case, ARTs are generally very long-lived, and therefore have a more persistent structure and mission than a traditional ______, which more classically has a start and end date.

(4.0) SAFe Principles of Agile Architecture

1. Design emerges. Architecture is a collaboration. 2. The bigger the system, the longer the runway. 3. Build the simplest architecture that can possibly work. 4. When in doubt, code or model it out. 5. They build it, they test it. 6. There is no monopoly on innovation. 7. Implement architectural flow.

Agile Manifesto - 12 Principles

1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. 2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. 3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. 4. Business people and developers must work together daily throughout the project. 5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done. 6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. 7. Working software is the primary measure of progress. 8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. 9. Continuous attention to technical excellence and good design enhances agility. 10. Simplicity--the art of maximizing the amount of work not done--is essential. 11. The best architectures, requirements, and designs emerge from self-organizing teams. 12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

Safe Lean-Agile Principles

1. Take an economic view 2. Apply systems thinking 3. Assume variability; preserve options 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 intrisic motivation of knowledge workers 9. Decentralize decision-making

Inspect and Adapt

4 hour meeting at the end of each PI consisting of: 1. PI Demo 2. Performance measures 3. Retrospective 4. Problem Solving Workshop. This is a regular ceremony that provides teams and groups time to reflect, problem solve, and identify improvement actions. Teams Demonstrate the current state of solution to the appropriate stakeholders, thereby getting the fast feedback they need to need to steer a proper course. Performance measures are collected and analyzed. This is followed by a Retrospective and Problem Solving Workshop, which generates improvement stories and other process learnings, which can then be immediately incorporated during Release Planning.

These budgets may include both _________ and _________ elements. In accordance with accounting standards, enterprises may capitalize some percentage of the labor involved in creating software for sale or internal use. While software capitalization practices are well-established in many enterprises, they typicially are based on waterfall development. However, enterprises are often challenged to effectively treat these costs in an Agile environment. Often Finance will do one of two things: 1) they will block Agile and mandate waterfall development 2) they will expense all Agile development labor costs Neither option above optimizes economics over time.

Program Epics

Epics that are constrained to a single train. Because of their scope, impact and cost, they may be introduced through the kanban systems and portfolio backlog, or they may arise locally, but they require analysis and impact assessment—and some discussion with Program Portfolio Management—before implementation.

Identifies critical aspects of the target solution environment and its impact on usage, installation, operating, support, and even marketing, packaging and selling. Understanding _________ ___________ is critical to value delivery; it impacts development priorities, Capabilities, Features, and Non-functional Requirements, and sets the focus for DevOps and other solution-level functions. __________ _________ drives the Solution Intent.

Architectural Collaboration

In the context of Agile enterprise software systems we need BOTH fast, local control of Emergent Design (so teams react appropriately to changing requirements without excessive attempts to future-proof the system) AND global control of Intentional Architecture (the guidance needed to assure that the system as a whole has conceptual integrity and efficacy). Achieving the right balance of Emergent Design and Intentional Architecture drives the effective evolution of the system.

In order for both organizations to achieve optimal results, close collaboration and trust are required. ____________ may or may not be Agile, however either way they are treated as a separate Agile Release Train and participate in all the value stream ceremonies. SAFe Enterprises help their __________ become more Lean and Agile, to the economic benefit of both organizations.

Kanban

Meaning "signboard" in Japanese, ________ is a pull system that helps teams facilitate the flow of value by visualizing workflow, establishing WIP limits, measuring throughput and continuously improving their process. A __________ system is built up of workflow states, most of which have WIP limits. A few states (typically the beginning and end states) are not WIP-limited. The team defines the WIP limits and adjusts them. One way to measure flow is via CFD (cumulative flow diagram) that compares the "arrival curve" (to-do) against the "departure curve" (done). Also _________ can implement "classes of service" (standard, fixed date and expedite) to adjust to external pressures, milestones and dependencies. On the ________ board, classes of service are typically depicted as swimlanes.

Scrum of Scrums

Meets weekly (or more frequently) to discuss the health of the release train and to keep all the teams in synch. Gives visibility into progress, risks. dependencies and impediments. Answer typical 3 questions: Y)esterday, T)oday, B)locking. The RTE conducts the _____ _____ ______ meeting and holds a "meet after" session afterwards to address improvements.

(4.0) Team Kanban

Most teams use Scrum as their agile method. But some teams use ______ _______, particularly System Teams, DevOps and maintenance teams. In these contexts the response mandate, the rapid-fire nature of the work, fast-changing priorities and the lower value of planning the next PI make this their method of choice. However, these teams are still "on the train" and certain rules of the train must be applied. Generally, such teams don't invest as much time estimating or tasking as Scrum teams do; rather, they look at the needed work, split the bigger items where necessary and drive the resulting stories to completion mostly without concern for their size. However SAFe teams still need to estimate demand against capacity for PI planning, and they also participate in the economic estimation of larger backlog items. Their velocity is also understood and communicated throughout the entire ART.

They consist of the following: 1. Lean ________ _________ - used to assess internal and external progress for the entire portfolio. In the spirit of "the simplest set of measures that can possibly work", lays out a simple chart of Benefit, Expected Result and Metric Used. E.g. "Time To Market", "More Frequent Releases", "Number of Releases Per Year". 2. Portfolio Kanban Board - makes cross-program business initiatives visible, with the upper-half containing Architectural Epics and the lower-half containing Business Epics. The categories are: Funnel, Review, Analysis, Portfolio Backlog and Implementing. 3. Measuring Epics - Epic Burn-up Report (using story points), Epic Progress Report (done, in-progress, approved), Epic Success Criteria 4. Portfolio Management Self-Assessment - similar to ART self-ssessment (radar diagram) but different metrics (portfolio kanban, budgets, value streams, program management, portfolio metrics, program portfolio management team, strategy and Investment Funding, governance) 5. Enterprise Balanced Scorecard - assessment for each business unit

Developers and Testers

These people comprise the majority of an Agile Team. _________ write the code for the User Stories and conduct research, design, and prototyping with Spike stories. The _________'s responsibilities include collaborating with the Product Owner and testers to make sure the right code is being developed; pairing, writing the code, unit tests, and automated acceptance tests; and checking new code into the shared repository every day. ______ work collaboratively and in parallel with developers and Product Owners to define, write, and execute acceptance tests, as well as maintain the test cases in a shared repository.

Budgets

These provide the operating boundaries for the investment in people, expenses and other resources for an Agile Release Train. SAFe's Lean-Agile _______ approach eliminates the overhead and friction of project-based cost accounting, and instead allocates resources to long-lived teams of teams, each dedicated to implementing a portion of a value stream.

Iteration

This (synonymous with sprint) is a strict time-box in which teams deliver incremental value in the form of working, tested software. Each has a standard pattern: plan the ___; commit to a goal; execute; demo the work to the key stakeholders; and, finally, hold a Retrospective, wherein the team analyzes and determines changes necessary to improve its performance.

Code Quality

This is a mindset, culture, and set of technical of practices which help teams deliver: higher system quality; high velocity and agility; opportunity for enhanced innovation; and helps support the intrinsic motivation and pride of software development professionals. _____ _____ is one of the four Core Values of SAFe and is achieved in large part through adoption of Test-First Methods, Agile Architecture, Continuous Integration, and Refactoring, all of which are described in SAFe, plus pair work and collective ownership.

Program Increment (PI)

This is to the ART what a sprint is to the team—a cadence-based _______ ________ of time and value suitable for assessing system status, getting feedback, improving processes, re-planning, and portfolio-level review and road-mapping.

Portfolio Kanban

This system brings visibility, work in process (WIP) limits, and continuous flow to Portfolio Level Business and Architectural Epics. This system is typically under the auspices of the CTO/technology office, which typically includes Enterprise and System Architects.SAFe applies a _______ ________ system for the following reasons: * makes the strategic business initiative backlog fully visible * brings structure and visibility to the analysis and decision-making that moves these initiatives into implementation * provides WIP limits to ensure that the teams responsible for analysis undertake it responsibly and don't create expectations for implementation or unrealistic timeframes * helps drive collaboration among the key stakeholders in the business * provides a quantitative, transparent basis for economic decision making for these, the most important business decisions SAFe does this by filtering Epics through these stages: 1. Funnel - capture state 2. Review - preliminary estimates of opportunity, effort and cost of delay are given 3. Analysis - where more thorough work is done to establish viability, measure benefit, development and deployment impact, and potential availability of resources. A lightweight business case is developed. The epic is approved or rejected at the end of this stage. 4. Portfolio Backlog - epics given the "go" approval wait in this stage until capacity is available 5. Implementation - when capacity is available epics are transferred to the relevant program and value stream kanbans, where implementation begins. Epics can subsequently be tracked at the Portfolio using Metrics. 6. Done - the epic is done when it has met its success criteria

User Experience (UX)

While Agile Teams have the full responsibility for implementing the code, including the user interface (UI) elements, the ___ _____ designer works at the Program Level to provide cross-component and cross-program design guidance so as to provide a consistent _______ _______ across all the components and systems of the solution.

Enterprise Architect

Works with business stakeholders and System Architects to drive holistic technology implementation across programs. The ______ ______ relies on continuous customer and team feedback, fosters adaptive design and engineering practices and drives collaboration of programs and teams around a common technical vision.

(4.0) Shared Services

_____ ______ in SAFe are those roles that are necessary for success of a Value Stream, but that cannot be dedicated to a specific train. These resources may include security specialists, information architects, DBAs, documentation, quality assurance, IT, and more. As the resources are specialized, often single-sourced and typically quite busy, each ART has to actively understand and plan to get the resources they need, when they need them. In some cases the resources must be *leading* and proactively track ahead (e.g. security, information architecture), whereby they contribute directly to the Architectural Runway that supports new Capability or Feature development. In other cases, the resources are *trailing* (e.g. IT/Deployment, support, customer training, localization) and being supportive and reactive is sufficient. In either case the _______ ___________ must travel synchronously with the ART to support its programs.

Feature/Benefit Matrix

______ / ______ Matrix _____: short phrase, giving a name and some implied context to the _____ _____: a brief description of the _____ to the user and the business. There may be multiple ______ per _____ which are highlighted here

(4.0) Lean-Agile Leaders

_______ ______ _______ _______ are ultimately responsibility for adoption, success and ongoing improvement of Lean-Agile development. These people are made up of the Enterprise's existing managers, leaders and executives. They are lifelong learners and teachers who help teams build better systems through understanding and exhibiting the Lean-Agile Mindset, SAFe Principles, and systems thinking. Such leaders exhibit the behaviors below: 1. Lead the Change 2. Know the Way; Emphasize Lifelong Learning 3. Develop People 4. Inspire and Align with Mission; Minimize Constraints 5. Decentralize Decision Making 6. Unlock the Intrinsic Motivation of Knowledge Workers

(4.0) Customer

_______ are the ultimate economic buyer of every solution. They are part of the Value Stream, and are inseparable from the process. They work frequently with Solution and Product Management to shape the Solution Intent, Vision and Economic Framework in which development occurs. They have strong influence in defining and prioritizing the solution's development and are active participants in solution planning, demos and process improvement.

(4.0) Solution Intent

________ __________ is the critical knowledge repository to store, manage and communicate what system builders are building and how they are going to build it. It serves many purposes: * provides a single source of truth as to the intended and actual behavior of the solution * records and communicates requirements, design and system architecture decisions * facilitates further exploration and analysis activities * aligns the customer, the system builders and suppliers to a common purpose * supports compliance and contractual obligations The ________ _________ consists of variable and fixed contents. Much of this information reflects the intended behavior of the solution -- Features and Capabilities, Stories, Nonfunctional Requirements, System Architecture, domain-level models and designs (e.g. electrical and mechanical), interfaces, customer specifications, tests and test results, traceability, etc. Other relevant information records some of the key decisions and findings about the system. This may include information from trade studies, results of experiments, rationale for design choices, and so forth.
