Testing Cost Calculator

NOTE: This tool is intended for experienced Maximo project managers and experts that are competent to estimate number of bugs/defects and costs for typical Maximo projects of the given size. We strongly recommend that you first read the full explanation of the principles behind this calculator that can be found here.

Parameters

Project Currency:
Estimated number of tests:
Project length in months:
Number of developers:
Expected number of bugs:
Daily regression runs:
Number of formal test phases:
Iterations per test phase:
Number of UATs:
Iterations per UAT:

One of the key factors in the program’s calculations is the fact that the cost of a bug dramatically increases with the “lateness” of its discovery: the later in the project cyclus the bug is discovered, the (much) higher its impact and the total cost to fix it.

Coding Phase Bug Cost Perica:
Code Integration Bug Cost :
Testing Phase Bug Cost :
UAT Phase Bug Cost :
Test developer daily rate :
Days to develop a test:
Days of maintenance per test:
Licence cost :
Manual tester daily rate :
Days to perform a test:
