Performance Testing Core Principles: CCD IS EARI

This is the first installment of a currently unknown number of posts about heuristics and mnemonics I find valuable when teaching and conducting performance testing.
 
Other posts about performance testing heuristics and mnemonics are:
 
 
There is not a "one-size-fits-most" approach to performance testing, but I have become rather convinced that there are nine principles that are (almost always) applied (or at least actively considered) in successful performance testing projects. I remember those principles by remembering:
 
CCD IS EARI
  • Context: Project context is central to successful performance testing.
  • Criteria: Business, project, system, & user success criteria.
  • Design: Identify system usage, and key metrics; plan and design tests.
  • Install: Install and prepare environment, tools, & resource monitors.
  • Script: Implement test design using tools.
  • Execute: Run and monitor tests. Validate tests, test data, and results.
  • Analyze: Analyze the data individually and as a cross-functional team.
  • Report: Consolidate and share results, customized by audience.
  • Iterate: "Lather, rinse, repeat" as necessary.
