Three Management Reports for the price of two:
- Software Project Estimates – How Accurate?
- Software Project Costs
- Outsourcing/Offshoring Performance Analysis
Software Project Estimates – how accurate are they?
We look at estimates of size, effort, duration and cost; how people have gone about estimating their projects; the accuracy of the estimates and the relationships between estimates. Here are some of the findings:
Size estimates are usually based on a data model; functional specification or analogy with a previous project
Project effort estimates are only accurate for less than a quarter of projects
Despite effort being poorly estimated 51% of projects were delivered on time
When functional size-based techniques are used for a cost estimate, the estimate is within 20% of the actual cost 90% of the time.
Software Project Costs
In this report we look at costs per function point and costs per hour, and provide some useful rules of thumb.
Outsourcing, Offshoring, Inhouse – How do they compare?
In this report we present the results of an analysis of the projects in the ISBSG R10 Development & Enhancement repository in order to answer the following questions:
1. How do outsourced projects compare to in-house projects? Are there any differences in the types of projects, the methods used, or the indicators of project performance?
2. How do onshore projects compare to offshore projects?
