Requirements Management Introducing RequisitePro Documenting Requirements Organizing Requirements Tracking Requirements Advanced Features

What is requirements management? a systematic approach to eliciting, organizing, and documenting the requirements of a system a process that establishes and maintains agreement between the customer and the project team on the changing requirements of a system.

Why is requirements management important? projects must be delivered on time and on budget they must address the client's needs

Requirements Management Skills

What should you consider when managing a project? What is the business problem you are trying to solve, and who has a stake in its resolution? What features are essential to a solution? How can the proposed solution be described in language that can be understood by technical and non-technical people? What are the available resources (time, people, money)? How should requirements be prioritized?

What should you consider when managing a project? (cont.) How can one verify that the system will function as described and perform with acceptable speed and efficiency? How can dependency relationships between requirements be traced? How can changes to the system be limited and negotiated so that the product can be completed and stakeholders remain engaged? What is the procedure for reviewing and resolving changes to requirements?

What are the causes of project failure? a large percentage of projects do not succeed. Standish Group listed lack of user involvement and changing requirements and specifications as among the top 10 factors that most frequently contribute to project failure.

The Problems of Requirements Management

The Problems of Requirements Management (cont.) Requirements are not always obvious and have many sources. Requirements are not always easy to express clearly in words. Many different types of requirements at different levels of detail must be managed. The number of requirements can become unmanageable if not controlled. Requirements are related to one another and to other deliverables of the process in a variety of ways.

The Problems of Requirements Management (cont.) Requirements have unique properties or property values; they are neither equally important nor equally easy to meet. Many interested and responsible parties are involved in a project, which means that requirements must be managed by cross- functional groups of people. Requirements change. Requirements can be time-sensitive.

Project Templates RequisitePro provides the following project templates:  Use-Case Template (using a use-case methodology)  Traditional Template (using standard software requirements)  Composite Template (a combination of the Use Case and Traditional templates)

Example Add a new template

A RequisitePro Project a project includes a database it can also include documents Included in the database :  document types glossary document, vision statement, use cases  requirement types categories of requirements such as features, use cases, supplementary specifications and …  requirement attributes describe the requirements in terms of priority, status, stability, and other characteristics that you define

Document Type document types:  Vision. gives the overall view of the system: main characteristics, major features, key stakeholder needs, and key services provided.  Glossary. a tool to capture and define the terms used in the project.

Document Type (cont.)  Use-case specification. a format to express functional requirements in sequence. A sequence of actions a system performs that yields an observable result (a work output) of value to a particular actor.  Supplementary specification. captures any requirements that cannot be tied directly to any specific use case, and especially many of the nonfunctional requirements and design constraints.  Test plan. describes the target-of-test (components, application, system) and its goals; the stages of testing; and the types of testing that will be addressed by this plan.

Requirements A requirement describes a condition or capability that a system must provide. They contain:  Name,  Text,  Tag,  Attributes to provide specific details.

Requirements (cont.) Requirements may be created in a document or in a view. All requirements information is stored in the database.

Requirement Types A requirement type defines descriptive and operational information associated with a requirement. serves as a template for all requirements of the same type. is useful for ensuring consistency and classifying or grouping similar requirements in a project.

View a table (matrix ) an outline tree create a view to display :  requirement attributes (status and priority )  to show the relationships between requirements.

View (cont.) You can create three different kinds of views: Attribute Matrix view  displays all requirements of a specified type  The requirements are listed in rows  their attributes appear in columns  helps you organize and prioritize requirements

View (cont.) Traceability Matrix view  help you manage the ripple effects caused by a requirement change  displays the relationships between two types of requirements or requirements of the same type

View (cont.) Traceability Tree view  help you manage the ripple effects caused by a requirement change  displays the chain of traceability to or from requirements of a specified type

Example Creating Requirements

Requirements Management Introducing RequisitePro Documenting Requirements Organizing Requirements Tracking Requirements Advanced Features

Tracking Requirements Topics to be covered: Managing changing requirements Setting traceability Managing change through traceability views Using suspect links Establishing hierarchy Querying (filtering and sorting)

Managing Changing Requirements includes (but is not limited to) the following activities: Keeping track of the history of each requirement Establishing traceability relationships between related requirements Maintaining version control

Setting Traceability a directional relationship between any two requirements  ReqA --> ReqB  ReqA <-- ReqB

RequisitePro's Traceability helps assure the quality and completeness of your products Link abstract requirements trace from use cases to the features requested by stakeholders can define the dependencies among requirements of the same type or different types

Managing Change Through Traceability Views Traceability Matrix Traceability Tree

Example Create and clear traceability relationships from a matrix view

Example Create traceability relationships from the Word document

Using Suspect Links the relationship between the requirements requires attention RequisitePro signals this suspect condition in a Traceability Matrix or Traceability Tree

Using Suspect Links (cont.) when either of the requirements has been modified after the initial traceability relationship has been established. In a Traceability Tree In an Attribute Matrix with an "(s)" in the Traced to or Traced From columns

Example Create a suspect relationship

Example Create suspect relationships in an Attribute Matrix view

Establishing Hierarchy hierarchical requirement Hierarchical relationships Child requirement dependency

Example Create hierarchical requirements in a document

Example Change the parent of a child requirement

Querying (Filtering and Sorting) After creating a view  Filtering restricts the information being displayed  sorting determines the order in which information is displayed by applying query criteria to the attributes

Example Create a query in an Attribute Matrix

Archiving  2 ways Creating baselines  baseline identifies activities and one version of every element visible in one or more components. It should be created at project milestones.  Rational Unified Change Management object

Archiving Example Create a version from current project

Advanced Features (cont.) Cross-project traceability  establish traceability between requirements that reside in different projects Customizing document and requirement types and attributes

Project Properties

Project Properties (cont.)

Advanced Features (cont.) Deleting requirements  Delete-Unmark  Delete-Remove  keep the requirement but modify the requirement attributes (recommended)

Advanced Features (cont.) Discussion groups  comment and raise issues and questions to a group of project users

Advanced Features (cont.) Integrations  Rational Rose for object-oriented analysis, modeling, design, and construction  ClearQuest for team-based change request management  TestManager for management of software testing assessments  ClearCase LT for configuration management  SoDA for project reporting and documentation  Rational Unified Process for incorporation of software development best practices.
