Application Design Review
Capacitas has extensive experience in reviewing applications in the early stages of the design lifecycle. This reduces the risk of suboptimal application performance due to poor design. It also allows design or development groups to ensure that the application will meet non-functional requirements.The key features of an application design review are:
- Collating non-functional requirements
- Assessing application SLAs to ensure they are meaningful and achievable
- Appraising of application design using design documentation, UML models, etc.
- Predicting application performance characteristics, e.g. end-to-end response time, business throughput, etc
- Decomposing application performance to highlight tuneable components
- Identifying application behaviour issues, e.g. instability issues, unnecessary idle times, nonessential application calls, unnecessary serialisation, etc.
- Identifying intra-component behaviour under load conditions, e.g. retry parameters, timeout conditions, etc.
Key Benefits
The benefits of employing Capacitas's Application Design Review include:- Helping ensure target dates for application deployment are met
- Ensuring applications are built to business service level requirements
- Avoiding expensive re-engineering of applications which do not meet performance requirements
- Promoting the development of applications which scale in line with business growth
- Greater cost control over application development by reducing performance test and fix phases
- Defining a roadmap for the development of a application performance assurance process
