Gather information
Use various techniques to make gathering requirements easier. Face-to-face meetings with stakeholders is the most
effective way to understand stakeholder needs and to gather and validate requirements, but you must prepare in order
for these meetings to run efficiently.
Be prepared by gathering and reviewing information related to the problem domain, problem statement, business
environment and key stakeholders. Most of this information must be available in the vision. Also review the
existing requirements repository for stakeholder requests.

Identify and capture domain terms
| If there are ambiguous or domain-specific terms that need to be clearly defined, make sure you work closely with
stakeholders to capture these terms in the glossary and that you use these terms consistently. |
Identify the types of requirements relevant to your system
Requirements can be broadly classified as either functional or non-functional requirements. The former specify what the
system must do. The latter specify constraints on the solution such as usability, reliability, performance,
supportability, interfaces with legacy systems, etc. Depending upon the domain there might be regulatory
requirements that apply.
Collaborate with stakeholders to identify the types of requirements relevant to your system. This will help you assess
the completeness of your requirement set.
|
Identify and capture Use Cases and Actors in a Use-Case Model
Find and define the line that divides the solution and the real world that surrounds the solution. Collaborate with the
project manager and architect, because decisions concerning system boundaries will have a major impact on cost,
schedule and system architecture.
Collaborate with stakeholders to identify interfaces, as well as input and output information exchanged with
users, machines, or systems. Identify and capture the Actors and Use Cases in the Use-Case Model. See Guideline: Identify and Outline Actors and Use Cases for more information.
|
Identify and capture use cases and scenarios
Collaborate with stakeholders to identify and capture the use cases and scenarios relevant to your system.
Capture references to these requirements with other project to-do items in the Work Items List so that you can prioritize the work.
See Identify and Outline Actors and Use Cases for more information.
|
Identify and capture system-wide requirements
Achieve concurrence
| Conduct a review of the requirements with relevant stakeholders and the development team to ensure consistency
with the agreed vision, assess quality, and identify any required changes. |
