Performance Engineering

Performance engineering within systems engineering, encompasses the set of roles, skills,  activities, practices, tools, and deliverable applied at every phase of the systems development life cycle which ensures that a solution will be designed, implemented, and operationally supported to meet the non-functional performance requirements defined for the solution. As the connection between application success and business success continues to gain recognition, particularly in the mobile space, application performance engineering has taken on a preventative and perfective role within the software development life cycle. As such, the term is typically used to describe the processes, people and technologies required to effectively test non-functional requirements, ensure adherence to service levels and optimize application performance prior to deployment.Adherence to the non-functional requirements is also validated post-deployment by monitoring the production system.
Objectives

• Increase business revenue by ensuring the system can process transactions within the requisite timeframe
• Eliminate system failure requiring scrapping and writing off the system development effort due to performance objective failure
• Eliminate late system deployment due to performance issues
• Eliminate avoidable system rework due to performance issues
• Eliminate avoidable system tuning efforts
• Avoid additional and unnecessary hardware acquisition costs
• Reduce increased software maintenance costs due to performance problems in production
• Reduce increased software maintenance costs due to software impacted by ad hoc performance fixes
• Reduce additional operational overhead for handling system issues due to performance problems.
