Agile Process Maturity Model

1Core Agile

Development

Focus is on construction

Goal is to develop a high-quality system in an evolutionary, collaborative, and self-organizing manner

Value-driven lifecycle with regular production of working software

DisciplinedAgile Delivery

Extends agile development to address full system lifecycle

Risk and value-driven lifecycle

Self organization within an appropriate governance framework

Agility at Scale

Addresses one or more scaling factors: Team size Geographical

A user story is… a simple, clear, brief description expressing a user’s goal for using

the system under development to deliver business value

A use case is…the specification of a set of actions performed by a system,which yields an observable result that is, typically,of value for one or more actors or other stakeholders of the system. (Unified Modeling Language - UML 2.0)

Both methods are focusing on users and values to the usersEach has its own challengesChoose use cases for green-field development and user stories for incremental releases

From use case to user story

66 6

User story: Ron Jeffrey’s 3 Cs

Card What is the goal of a user

As a (user role), I want to (goal) so I can (reason)Example: As a registered student, I want to view course details so I can create my schedule

Conversation How to achieve the goal using the system?

Discuss the card with a stakeholder. Just in time analysis (JIT) through conversations.Example:What information is needed to search for a course?What information is displayed?

Confirmation How to verify if the story is done and complete, and the goal is achieved

Record what you learn in an acceptance test. Example:

Student can access course catalog 24 x 7 hours

Student cannot choose more than three courses

INVEST in good stories

Right-size user storiesCapture constraints as part of user stories

Write closed storiesInclude user roles in the stories

User stories and iterative planning

Write initial stories, estimate high-priority stories, and develop high-level release plan at beginning of project

Each iteration, pull one iteration’s worth of work off the stack based on your velocity

9

Agile requirements project template

The agile requirements project template includes a set of folders and a document template to elaborate a user story

Project Folder: Stakeholder Needs Features Glossary Non-functional Requirements User Story Elaboration Document Template: User Story Elaboration

Use the template to create a new Requirements Composer project Customize the template based on your project needs

Potential artifacts for the User Story Elaborations folder

14

Potential artifacts: Flow diagrams for scenarios

A scenario can involve multiple user stories

Roles and personas User story elaboration UI sketches Storyboards

1515

User story elaboration - example

15

A user story may start as a short statement, explaining the intent of the userIt can be elaborated through conversations and confirmation, leveraging techniques such as user interface sketches, and storyboarding

1616

Strategy of describing and managing epics

Process sketch or storyboard can visually describe an epic Break down an epic into user stories to elaborate the details Use a collection to manage a group of related user stories

16

1717

Analyzing elaborated stories using attributes, tags, and filters

Display all elaborated user stories with their attribute values Filter and display elaborated story based on attribute values

By Business PriorityBy OriginBy Product OwnerBy Role

Organize elaborated stories by themesDisplay elaborated stories in a collection
