or set of quality indicators (see Figure 2.11) that can be used to
determine:
• What is the quality of the artifact? Does it need rework?
• Has the artifact been completed? What are the criteria for
completion?
• What is the status of the artifact; e.g., suggested, draft,
completed, sunset?
Business and Customer Requirements Mandatory
Responsible: Prod M Contributing: RE, SA
Description: The Business Objectives and Customer Requirements identify the
primary benefits that the new system will provide to the customer and to the
organization that is developing the system.
Business Objectives Mandatory
Summarize the important business benefits the system will provide, preferably
in a way that is quantitative and measurable. The background and business
opportunities of the future system are described. This includes a description
of business problems that are being solved, and a comparative evaluation of
existing systems and potential solutions. The rationale for the system
development is described, and how the system aligns with market trends or
corporate strategic decisions is defined.
Customer Requirements Mandatory
Summarize the needs of typical customers or users. Customer needs are
defined at a high level for any known critical conditions, interface, or quality
requirements. They provide examples of how the customer will use the system
and identify the components (hardware and software) of the environment in
which the system will operate. Explicitly define the value the customer/user
will receive from the future system and how it will lead to improved customer
satisfaction.
Purpose: Business and customer requirements serve as entry points to
context analysis and the specification of the required features and
characteristics of the System Vision and the definition of the general
Conditions & Scope of the development.
By identifying the business objectives, the situation, and the critical conditions,
collect business risks associated with the developing (or not developing) this
system systematically as input to risk and cost/benefit analysis (ROI & Risk).
References: [Wie 1999] gives an overview of business requirements and provides
a list of possible customer values.
