Study Notes

Requirements Prioritization

Requirements prioritization is the process of selecting the most valuable requirements from a set of candidate requirements to ensure that the needs of customers and users are met.
Prioritization helps to identify the most valuable requirements by distinguishing the critical few from the trivial many.
The quality of a software product is determined by its ability to satisfy the needs of customers and users.

What is Requirements Prioritization?

Prioritization is a challenge that requires balancing multiple factors and achieving a balance is essential for effective prioritization.
It involves making decisions about which requirements to address first, considering the strategic goals and objectives of the project.
The set of candidate requirements refers to the complete pool of features, functionalities, or specifications that could be included in the software product.

Key Points about Prioritization

Requirements prioritization is crucial during the Requirements Analysis phase.
It helps focus on critical functionalities first, ensuring that the most valuable features are implemented early in the development process.
It provides a roadmap for development teams, guiding them in addressing potential challenges early on.

Aspects of Prioritization

Importance: depends on the stakeholder's perspective and can be multifaceted, considering factors like urgency, strategic importance, and product architecture.
Penalty: the disadvantage or consequence of failing to comply with a requirement, which can impact the project and final product.
Dependencies: relationships between two or more requirements, where one cannot be completed or implemented properly without the other.
Time Sensitivity: the time limit for implementing requirements, considering factors like seasonal demands and deadlines.
Stability/Volatility: the likelihood of a requirement remaining constant and static.
Regulatory/Policy Compliance: meeting regulatory or policy requirements, such as laws, trade regulations, and corporate policy.
Cost: the estimated cost of implementing a requirement, influenced by factors like complexity, reusability, and testing.

Combining Different Aspects

In practice, it is essential to consider multiple aspects before deciding if a requirement should be implemented directly, later, or not at all.
Examples of combining different aspects include the Cost-Value approach, which prioritizes value and cost, and Importance-Effort-Risks, which considers importance, effort, and risks.

Prioritization Techniques

MoSCoW Method: categorizes requirements into Must-haves, Should-haves, Could-haves, and Won't-haves based on their importance and feasibility.
Kano Model: classifies requirements into Basic Needs, Performance Needs, and Excitement Needs, considering their impact on customer satisfaction.
Numerical Assignment (Grouping): assigns numerical values to requirements based on their priority, using groups like critical, standard, and optional.
