Concepts
Requirements traceability is an integral part of the Project Management Institute Professional in Business Analysis (PMI-PBA) examination and an important technique for requirements management. Therefore, it is necessary to understand how to define a strategy for requirements traceability using traceability tools and techniques. This strategy should assist in defining the level of traceability required to monitor and validate the requirements.
I. Traceability in Project Management
Traceability in project management is a process used to document the origin of a requirement, including its development and ultimate implementation. The main goal is to ensure that all requirements have been tested and implemented. Requirement traceability can be categorized into pre-traceability, forward traceability, and backward traceability.
- Pre-traceability: This is the process of tracing relevant documents produced during the requirements elicitation or analysis phases.
- Forward traceability: This process involves tracking the requirements from their source to its implementation.
- Backward traceability: It permits the tracking of requirements from their implementation back to their origin.
Each of these traceability methods comprises its unique tools and techniques, which will be discussed in the following section.
II. Traceability Tools & Techniques
- Traceability Matrix: The Traceability Matrix is a document in table format used to trace the requirements from their origins through their entire lifecycle. It links the requirements to its source, its part in the system design, and the test cases that validate the requirement.
- Future Scenerio: Using the information gathered about requirements, a projection of the potential scenarios can be made to validate them.
- User Stories & Refined Models: These techniques involve the use of scenarios, processes, and usage diagrams to validate requirements.
- Proof-of-concept: A prototype can be developed to test a concept or solution and ensure the accuracy of the requirements.
These traceability tools, when efficiently used, pave the way to ensure the accuracy and implementation of all defined requirements.
III. Level of Traceability
Determining the level of traceability that will be required for the project is a strategic decision that needs to be thoroughly assessed. Some factors to be considered when deciding the level of traceability include:
- Regulatory Restrictions: The level of traceability may be high if there are numerous and strict governing rules and regulations.
- Stakeholders Expectations: The level of scrollability depends on the wish of the stakeholders. For instance, a stakeholder might wish to trace high-level business requirements only.
- Complexity of the Project: If projects are very complex with many deliverables from various teams, a higher level of traceability will be required to manage the requirements.
- Risk Level: Higher risk levels require a higher degree of traceability to ensure all risks are addressed and mitigated.
IV. Conclusion
In conclusion, establishing a strategy for requirements traceability using traceability tools and techniques is a significant aspect of project management. A well-structured Traceability Matrix can boost the efficiency of managing project requirements, reduce the occurrence of scope creep, and most importantly, fulfill stakeholder expectations. Deciding the level of traceability necessary for monitoring and reviewing requirements should be a strategic decision based on several factors including regulatory restrictions, stakeholders expectations, project complexity, and risk level. Remember, a traceability strategy should be well tailored to fit your project requirements and constraints.
Answer the Questions in Comment Section
True or False: Requirements traceability is the tracking of requirements throughout the lifecycle of a project.
Answer: True
Explanation: Requirements traceability allows the lineage of each requirement – from its origins, through its development and specification, to its subsequent deployment and use, to be examined in detail.
Which of the following is NOT a benefit of requirements traceability?
- a) Improved communication among project team and stakeholders
- b) Validates that all requirements have been implemented
- c) Helps in identifying the cost of the requirement
- d) All of the above are benefits of requirements traceability
Answer: d) All of the above are benefits of requirements traceability
Explanation: Requirements traceability improves communication, validates requirements implementation, and aids in cost identification.
True or False: The level of traceability necessary for a project can vary depending on the project’s complexity and organization’s needs.
Answer: True
Explanation: The level of traceability necessary can vary and should be defined based on project and organization needs.
Which of the following is NOT a step to define a traceability strategy?
- a) Identify traceability objectives
- b) Calculate total project cost
- c) Select the right traceability tools
- d) Maintain the traceability information
Answer: b) Calculate total project cost
Explanation: Defining a traceability strategy involves determining objectives, selecting tools, and maintaining information, not calculating project costs.
Multiple Select: Which of the following are commonly used traceability tools?
- a) Requirement management tools
- b) Project management software
- c) Spreadsheets
- d) Video conferencing tools
Answer: a) Requirement management tools, b) Project management software, c) Spreadsheets
Explanation: Requirement management tools, project management software, and spreadsheets are IT tools used to trace requirements.
True or False: There is a single level of traceability that fits all project contexts.
Answer: False
Explanation: The level of traceability necessary can depend on many factors such as the project’s nature and complexity.
Traceability matrix is a tool used to:
- a) Allocate resources
- b) Schedule tasks
- c) Track requirements
- d) Establish communication plan
Answer: c) Track requirements
Explanation: A traceability matrix is a document that co-relates any two-baseline documents that require a many-to-many relationship to check the completeness of the relationship.
True or False: Traceability helps in identifying the impact of a change in requirement.
Answer: True
Explanation: Traceability helps understand the dependencies between requirements, making the impact of change easier to identify.
Which of the following technique is NOT used for requirements traceability?
- a) Use case diagrams
- b) Work breakdown structure
- c) Traceability matrix
- d) Brainstorming
Answer: d) Brainstorming
Explanation: Brainstorming is a technique used to generate and gather ideas, not for tracing requirements.
True or False: Establishing and maintaining requirements traceability is a one-time effort.
Answer: False
Explanation: The process of establishing and maintaining requirements traceability is ongoing and needs to be updated as the project progresses and requirements change.
Multiple Select: The purpose of requirements traceability includes:
- a) Mapping the relationship between varying levels of requirements
- b) Confirming every requirement is implemented
- c) Determining the scope of the project
- d) Understanding the impact of changing a requirement
Answer: a) Mapping the relationship between varying levels of requirements, b) Confirming every requirement is implemented, d) Understanding the impact of changing a requirement
Explanation: Requirements traceability is used for mapping relationships between requirements, confirming their implementation, and understanding their impact, not for determining project scope.
Which of these is NOT a characteristic of a good traceability tool?
- a) Ability to provide real-time updates
- b) High learning curve
- c) Support for various types of links
- d) Support for large-scale requirements
Answer: b) High learning curve
Explanation: A good traceability tool should be easy to use and learn, thus a tool with a high learning curve may not be the best option.
