The bridge to measureable IT success!

Productivity in IT development

The productivity in IT development describes the ability up to which costs and in which time frame the organisation is either able to self-develop software or alternatively can provide customised COTS software. 

To us, the differentiation is very important - because: the statement that higher productivity can be achieved with the help of COTS software rather than the self-developed solution - this is (often) as true it is false simultaneously. True, concerning the development speed and therefore the "time to market". False, if costs are taken into consideration. At this stage our analyses show that commonly there is a cost advantage in self development. 

How can you decide?

Decisive are obviously a range of criteria. With our investigations regarding productivity you will get first of all dues for the evaluation of the status quo of your organisation. You can only decide for yourself which aspects are important to you. We provide the information for you!

Brief description

To determine the productivity we compare as reference, to completed development projects or projects which are still in process. In the latter case all sufficient information about functional scope, costs and time should be available in order to obtain results about the development.

This approach has a lot in common with the method of function point analysis of bc. Depending on the number of selected developments, the expenditure has to be multiplied accordingly for a review. For the estimation of the actual expenditure and cost rates, support through management accounting and respectively IT controlling is needed.

  • Evaluation of productivity of change
      • Evaluation of development time: FP/PM (Change)
    • Evaluation of development costs: EUR/FP (Change)

 

The realisation is as following:
