Performance Measurement and Analysis

Search:   

GIFPA provides a range of services to determine what measures are appropriate, collect and analyse the data. We also offer consultancy to enable organisations to develop or improve their own performance measurement and analysis capabilities.

When does it happen?

Performance Measurement and Analysis can occur at any point in a product life cycle or project. To provide control of a project, maintenance or support programme it should be an on-going process planned as part of a Measurement Programme.

When assessing suppliers or investigating the feasability of a new project or programme of work the preformance of previous projects can be measured and analysed. These must be chosen carefully to give a good performance estimate for the likely internal resources and / or external suppliers.

What do you measure?

Many software metrics are standard measures that would be applied to any manufacturing or engineering business, such as labour (staff effort), time to market, defect rates. Others are software or systems specific measures such as functional size.

How do you analyse the results?

The raw metrics are used to produce derived measures which show different performance characteristics. These are most often measured in terms of functional size of the software being developed, maintained or supported. For example:

  • Productivity = cost / function point

or

  • Productivity = function points / effort

Other measures include:

  • Quality (or defect density) = Defects / 1000 Function Points
  • Speed of Delivery = function points / duration
