Gather Information
Use different techniques to make gathering requirements easier. Face-to-face meetings with stakeholders are 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 top-level system goals
| The first step is to use the acquired information to identify the most important, top-level system goals. These are usually
abstract descriptions of the overall purpose of the system. |
Refine top-level system goals to more granular goals
| Break down the top-level goals to smaller goals that contribute to reaching the top-level goals. Denote relationships
between top-level and sub-goals and document the refinements made. |
Identify obstacles that can hinder the system from reaching its goals
| Think of environmental, regulatory, or technical obstacles that might prevent certain goals from being reached. Document
the obstacles and their relationship to the individual goals. |
Identify assumptions about the environment and the system
| Identify the implicit assumptions that you make when thinking about goals and obstacles. Do you expect a certain user
behaviour? Do you assume that certain economic incentives are in place? Do you assume high quality of information? Document
these assumptions and the possible impact if they turn out to be false. |
