  6. 6. Productivity Equals Application Performance The key to productivity in interactive applications is response time: • .1 second is instantaneous • 1 second is when a response time is perceived • 10 seconds is when users lose focus on the interaction Basic rules • Simple and frequent tasks: 1 second or less • Common tasks: 2 to 4 seconds • Complex tasks: 8 to 12 seconds Source: Usability Engineering by Jacob Nielsen (Morgan Kaufman San Francisco) Kaufman, 7 Entire contents © 2008 Forrester Research, Inc.

But… Trends and Challenges • User’s performance expectations are rising as IT budgets are squeezed • Application business value and complexity increases – M lti ti applications are th norm Multi-tier li ti the • Time to value reduced through re-use, web services and SOA • Interoperability, portability, device diversity and size leads to configuration, deployment and production issues that impact performances • Outsourcing, hosting, cloud computing and virtualization opacity p p y present new challenges g 8 Entire contents © 2008 Forrester Research, Inc.

  10. 10. Translates into Performance Issues • As the size of software increases, the number of problems per KLOC increases proportionally • 74% of problems are reported by the end users through the service desk, not detected by infrastructure management • An average of 6 service desk calls are needed to identify the problem owner • Typical SLA: 95% of level 1 problems are answered in 2 hours IT Operations are bursting at the seams Source: Forrester Research 11 Entire contents © 2008 Forrester Research, Inc.

  15. 15. What we Should do: • Validate application architecture at the development stage and create a performance hypothesis • Validate performance hypothesis in QA: – Using a realistic environment – Using end to end monitoring tools • Understand the workload variations – What are the normal performance levels for a given period – Distinguish between real problems and transient variations and anomalies • Consider efficient alternatives such as SaaS to in house testing and monitoring 16 Entire contents © 2008 Forrester Research, Inc.

  16. 16. Recommendation: Towards a Leaner IT • IT evolution drivers are economical rather than technical – Improving workforce productivity and IT efficiency are the key themes • Simplification and standardization of infrastructures will be the dominant themes of the next five years • Any initiative such as consolidation, standardization, IT governance improvement or service management requires improvement, preparation – Understanding workloads and performance issues are key • Productivity and efficiency objectives are only reached when we consider all alternatives to perform a given performance management function g 17 Entire contents © 2008 Forrester Research, Inc.

  17. 17. Conclusion • The major driver for IT management and IT Operation evolution is to improve business productivity as efficiently as possible • Many current management solutions are still very much technology silo oriented and ignore the end user perspective • Most of the current tools compound the issue by adding complexity of deployment and operation • The consensus is that IT service delivery is better served not only by improved IT management processes, but also by monitoring solutions b it i l ti based on th S S model th t provide th d the SaaS d l that id the right data for an optimized operational cost 18 Entire contents © 2008 Forrester Research, Inc.
