Requirements refer to the conditions or capabilities needed by the stakeholders for a system to solve a problem to achieve an objective. They are the characteristics of a project or product that are expected by the end-users.
Now, let’s talk about these requirements from different stakeholder’s perspectives:
- Business Requirements: Business requirements consider the high-level business strategy and objectives of the organization.
- Stakeholder Requirements: These requirements come from different stakeholders of the project.
- Solution Requirements: Solution requirements articulate the features, functionality, and characteristics of the product, service, or result of the project. These are further categorized into functional and non-functional requirements.
- Transition Requirements: They are the conditions necessary for switching from the current state to the new one, crucial during the implementation stage of a project.
The ultimate goal here is to take all these requirements into consideration and create a scope statement that clearly defines what the project will deliver.
2. Determining and Prioritizing Requirements
Once you have identified different requirements, the next step is to determine and prioritize each one in alignment with project objectives.
Here are a few techniques that aspiring project managers can use to determine requirements:
- Document analysis
- Interviews
- Focus groups
- Workshops
- Surveys or questionnaires
- Prototyping
Remember, success largely depends on your ability to manage and prioritize these requirements. Here are some strategies you can apply:
- Hierarchization: Rank the requirements based on their importance. High ranking requirements will have a higher priority.
- MoSCoW method: This technique stands for Must have, Should have, Could have, and Won’t have.
- Pairwise Comparison: In this method, all possible pairs of requirements are compared to identify which of each pair is more critical.
- Voting: Stakeholders can also vote for what they perceive as essential.
3. Requirements Traceability Matrix (RTM)
The Requirements Traceability Matrix (RTM) is a table that helps project managers identify, define, and track requirements throughout the project. It systematically aligns each requirement to the project objectives, providing a clear view of the relationship between them and helping you to prioritize effectively.
An example of an RTM might include columns such as:
| Requirement ID | Requirement Description | Priority | Origin | Deliverables |
|---|---|---|---|---|
| R1 | Comprehensive search feature | High | Customer interview | Website |
| R2 | User-friendly interface | Medium | Market analysis | Application |
All this discussion brings us to the conclusion that effective requirements management is fundamental to successful project execution. It plays a significant role in reducing project risks, aids in controlling project scope, and immensely helps in delivering the desired project solutions. It is therefore a significant part of the PMP exam, and aspiring project managers must thoroughly understand how to determine and prioritize project requirements.
