This presentation reviews how requirement prioritization is a decision process used to determine the relative importance of requirements. The importance of requirements may be based on their relative value, risk, difficulty of implementation, or on other criteria. These priorities are used to determine which requirements should be targets for further analysis and to determine which requirements should be implemented first. We shall discuss the inputs, techniques used, and the expected outcome. Prioritization of requirements ensures that analysis and implementation efforts focus on the most critical requirements

- The definition of the business need is frequently the most critical step in any business analysis effort. Can you explain why?Give an example of what has happened in your world when the business need was not clearly identified and defined.Purpose - To create a set of views of the requirements for the new business solution that are comprehensive, complete, consistent, and understood from all stakeholder perspectives Two Objectives - To understand which models are appropriate for the business domain and solution scopeIdentify model interrelationships and dependencies
- Can you explain what the desired outcome should do, if it isn’t a solution ? (page 84)In reality, desired outcomes should address a problem or opportunity, and support the business goals and objectives. Proposed solutions must be evaluated against desired outcomes to ensure they can deliver those outcomes.The business analyst determines which types of models will be required to describe the solution scope and meet the informational needs of stakeholders. Modeling concepts relative to Business Analysis:User Classes, Profiles or RolesConcepts and Relationships Events Processes Rules
- Remember – any changes to the scope need to be approved by the sponsor!Domain SME, End User, Implementation SME & SponsorAffected by analysis techniques used to organize requirements since they need to verify and validate the requirements. The business analyst tailors the approach to meet the needs of key stakeholder groups, and must determine which models will be useful to each.Project ManagerUses the organized set of requirements to verify the scope of the solution and assess the work that needs to be done in the project.
- The deliverable is a statement of the business need. Requirements Structure: The output of this task is an organized structure for the requirements and a documented set of relationships between them. This structure is distinct from tracing and is used so that the analyst and stakeholders know where a specific requirement should be found

- What is the definition of a goal? Section 5.1.4 of the BABOK®defines them as longer term, ongoing, and qualitative statements of a state or condition that the organization is seeking to establish and maintain. Goals and objectives can relate to changes that the organization wants to accomplish, or current conditions that it wants to maintain. High-level goals can be decomposed to break down the general strategy into distinct focus areas that may lead to desired results, such as increased customer satisfaction, operational excellence and/or business growth. How can goals eventually be linked to specific measures? (page 83) As goals are analyzed, they are converted into more descriptive, granular, and SPECIFIC (remember the S in SMART!) objectives, and linked to measures that make it possible to objectively assess if the objective has been achieved. .1 Basis for PrioritizationRequirements may be prioritized using a number of different criteria:Business ValueBusiness or Technical RiskImplementation DifficultyLikelihood of SuccessRegulatory or Policy ComplianceRelationship to Other RequirementsStakeholder AgreementUrgency

Unrealistic Tradeoffs - The solution development team may intentionally or unintentionally try to influence the result of the prioritization process by overestimating the difficulty or complexity of implementing certain requirements.

- The deliverable is a statement of the business need. Requirements [Prioritized]: A prioritized requirement has an attribute that describes its relative importance to stakeholders and the organization. At the completion of this task, each requirement should have an assigned priority. The priorities may apply to a requirement or to a group or related requirements.
