Study Notes
Requirements Architecture
- A requirements architecture is the structure of all requirements of a change, ensuring they form a cohesive whole that supports business objectives and produces a useful outcome for stakeholders.
- It organizes requirements into structures relevant to different stakeholders, illustrating how they interact and relate to each other.
- It ensures all requirements work together to achieve overall objectives and facilitates trade-off decisions considering overall objectives.
Purpose of Requirements Architecture
- Not intended to demonstrate traceability, but to show how elements work in harmony to support business requirements.
- Ensures requirements work together to achieve overall objectives, making trade-off decisions possible.
Inputs to Define Requirements Architecture
- Information Management Approach: defines how business analysis information is stored and accessed.
- Requirements (any state): every requirement should be stated once and incorporated into the requirements architecture for completeness evaluation.
- Solution Scope: must be considered to ensure the requirements architecture aligns with the desired solution boundaries.
Elements of Requirements Architecture
Viewpoints and Views
- A viewpoint is a set of conventions defining how requirements will be represented, organized, and related.
- Viewpoints provide templates for addressing stakeholder concerns, including model types, attributes, notations, and analytical approaches.
- Examples of viewpoints include business process models, data models, user interactions, audit and security, and business models.
- Each viewpoint has different model notations and techniques, and each is important for a cohesive final solution.
- A view is the actual requirements and designs for a particular solution from a chosen viewpoint.
- A collection of views makes up the requirements architecture for a specific solution.
Template Architectures
-
An architectural framework is a collection of viewpoints standard across an industry, sector, or organization.
-
Frameworks can be used as predefined templates to start defining an architecture.### Definition of Requirements Analysis and Design
-
The Requirements Analysis and Design Definition knowledge area describes the tasks that business analysts perform to structure and organize requirements discovered during elicitation activities, specify and model requirements and designs, validate and verify information, identify solution options that meet business needs, and estimate the potential value that could be realized for each solution option.
Tasks in Requirements Analysis and Design
- Specify and Model Requirements: describes a set of requirements or designs in detail using analytical techniques.
- Verify Requirements: ensures that a set of requirements or designs has been developed in enough detail to be usable by a particular stakeholder, is internally consistent, and is of high quality.
- Validate Requirements: ensures that a set of requirements or designs delivers business value and supports the organization's goals and objectives.
- Define Requirements Architecture: structures all requirements and designs so that they support the overall business purpose for a change and that they work effectively as a cohesive whole.
- Define Solution Options: identifies, explores, and describes different possible ways of meeting the need.
- Analyze Potential Value and Recommend Solution: assesses the business value associated with a potential solution and compares different options, including trade-offs, to identify and recommend the solution option that delivers the greatest overall value.
The Business Analysis Core Concept Model
- The Business Analysis Core Concept Model (BACCM) describes the relationships among the six core concepts: Change, Need, Solution, Stakeholder, Value, and Context.
- Within the context of Requirements Analysis and Design Definition, the core concepts are used to:
- Transform elicitation results into requirements and designs (Change).
- Analyze the needs in order to recommend a solution that meets the needs (Need).
- Define solution options and recommend the one that is most likely to address the need and has the most value (Solution).
- Tailor the requirements and designs so that they are understandable and usable by each stakeholder group (Stakeholder).
- Analyze and quantify the potential value of the solution options (Value).
- Model and describe the context in formats that are understandable and usable by all stakeholders (Context).
Specify and Model Requirements
- The purpose of Specify and Model Requirements is to analyze, synthesize, and refine elicitation results into requirements and designs.
- This task includes capturing information about attributes or metadata about the requirements.
- The specifying and modeling activities relate to all requirement types.
- Models can be used to:
- Convey information to a specific audience in order to support analysis, communication, and understanding.
- Confirm knowledge, identify information gaps, and identify duplicate information.
- Business analysts choose from one or more of the following modeling formats:
- Matrices: used for data dictionaries, requirements traceability, or gap analysis.
- Diagrams: used to depict complexity in a way that would be difficult to do with words.
- Model categories can include:
- People and Roles: models represent organizations, groups of people, roles, and their relationships within an enterprise and to a solution.
- Rationale: models represent the ‘why’ of a change.
- Activity Flow: models represent a sequence of actions, events, or a course that may be taken.### Requirements Architecture
- A framework can be populated with domain-specific information to form a collection of views that serves as a template to build architecture from.
- Ensures that a set of requirements is complete, cohesive, and tells a full story.
- Helps identify gaps in requirements through iterations of elicitation, specification, and analysis activities.
Completeness
- The entire set of requirements should be understood by the audience in a way that determines completeness.
- No requirements should be missing, inconsistent, or contradictory to one another.
- Structuring requirements according to different viewpoints helps ensure completeness.
Relate and Verify Requirements Relationships
- Requirements may be related to each other in several ways, and business analysts examine and analyze these relationships.
- Relationships should be defined, necessary, correct, unambiguous, and consistent.
- Tracing requirements helps represent these relationships.
Business Analysis Information Architecture
- The structure of business analysis information is an information architecture.
- Defines how all business analysis information for a change relates.
- Describes relationships for types of information such as requirements, designs, models, and elicitation results.
Guidelines and Tools
- Architecture management software helps manage the volume, complexity, and versions of relationships within the requirements architecture.
- Legal/regulatory information, methodologies, and frameworks also impact the requirements architecture.
Techniques
- Data modelling, functional decomposition, interviews, organizational modelling, scope modelling, and workshops are used to define the requirements structure.
Stakeholders
- Domain subject matter experts, implementation subject matter experts, project managers, sponsors, testers, and any stakeholder may assist in defining and confirming the requirements architecture.
Outputs
- The requirements architecture includes the requirements and their interrelationships, as well as contextual information.
Define Design Options
- The purpose of Define Design Options is to define the solution approach, identify opportunities to improve the business, allocate requirements across solution components, and represent design options.
- Design options exist at a lower level than the change strategy and are tactical rather than strategic.
Inputs
- Change strategy describes the approach to transition to the future state.
- Validated and prioritized requirements are considered in design options.
- Requirements architecture is important for defining design options that can address the holistic set of requirements.
