Design phase

During the design phase of your project, it is important to consider performance priorities. It is important to design a solution that has a good balance of features and performance consideration, build a performance test environment, and begin to deploy tools that are required to support your performance strategy. It is also important to identify architecture limitations that might change a non-functional requirement.

During the design phase, a number of key activities are carried out. Here are some examples:

Review and validate non-functional requirements with IT and business stakeholders.
Assist with application flow design.
Educate developers on performance.
Review component design that is focused on performance.
Prepare system maintenance strategies.
Identify key performance indicators (KPI) for monitoring.

It is important to be aware of potential risks that might result from not considering performance during the design phase:

The possibility that features might put a greater demand on resources than projected over the capacity plan estimate.
Application performance and user experience might be adversely affected by third-party application interfaces.
The lack of an appropriate test environment might hamper performance testing capabilities and put test results into question.
