Chapter 7 ■ InItIal requIrements: DefInIng the proDuCt

Figure 7-1. Requirements cone of scope

• Mission statement: The ultimate goal of the product is to meet the expectations and

needs of the sponsor, who is paying for the project. Anything outside his mission

statement is out of scope. The PM should have collected this in the project charter

previously.

• Stakeholder expectations: Each stakeholder has expectations and needs that to justify

their involvement with the project. Each stakeholder captured those expectations

and needs in their business abstracts, which the PM should have reconciled

previously to build the project abstract.

• Business workflows and feature catalog: Each stakeholder has an idea of what

features are needed for the product, and sometimes enlist the aid of business SMEs

to help. At first, these are “desirements”: features that are like market points on

the back of a product box when it is sold. They become requirements after they

are vetted against the mission statement and practical considerations. They are

prioritized by business value, risk, and other factors (see Chapter 3) and listed as the feature catalog. Unlike an approved, and voluminous, software specification

document, the feature catalog is only a prioritized list that can be revised as needed

before construction starts with little or no project impact.

• Use case catalog: Each workflow is comprised of multiple transactional threads or

use cases, and each use case is known (at this time) only by its single-statement goal.

Each use case summary is a name and short description of the usage transaction.

The list of use case summaries are collected in priority order, correlated to feature

priorities, into the use case catalog.
