Performance Testing: Helping IT Help the Business

Performance Failures = Lost Revenue
The appalling news of performance failure leading to loss of revenue, emerging every now and then creates a chill in the spine. The reason, in a single word is ‘negligence’. The reluctance to define performance requirements usually comes from: lack of understanding the performance requirements, time constraints, limited budget, non-existent or incomplete performance specifications and ownership of systems which is not understood. All that we need to do at this juncture is, curb these.
Performance Goals and their importance
The first step in this regard is to realize the Performance Goals and their importance. To achieve the goals we need to describe considerations for a systems performance, break down performance goals into tasks and then emphasize the importance of making performance goals part of the IT software requirements definition.
Planning the performance goals should be the second move. In this stratum we need to realize the performance requirements in terms of Consumer Requirements, Data, Traffic and Business, plan the Requirements Phases and Responsibilities, and assign the roles and responsibilities accordingly.
Inter team communication is the third move, wherein the objectives should be set and requirements defined, but sometimes the business needs change. Note that the key to successful implementation of performance testing is continual communication among team members – manage change accordingly, because an effective mechanism of communication and collaboration allows the team to make good performance related decisions, whilst changes are easy to make. The methods you use to communicate plans, priorities and changes are not that important as long as you are able to adapt those changes without requiring significant re-work.
But before sorting out anything, we need to have an anatomy of the process- the performance testing process, which includes, Requirements, Discovery, Test Planning, Automation, Testing, Measurements, Analysis and Tuning and Re-Testing.
With this skeletal in the planning schedule, both the product and the process emerge as flawless, hence giving a breath of relaxation.
