All of the data submitted is subjected our quality assistance processes.  Each project is rated A to D.  Only A and B projects are included in any statistical analysis.

93% of projects are rated A or B.  Definitions for these ratings are

A = The data submitted was assessed as being sound with nothing being identified that might affect its integrity.

B = The submission appears fundamentally sound but there are some factors which could affect the integrity of the submitted data.

The free ISBSG Data Collection Questionnaires will give you ideas on the data to collect.  Some attributes are obvious but others are not and these additional attributes may turn out to be significant when looking for factors that impact productivity.

The three main attributes that people look for are: effort, size and duration.  These factors yield information about the productivity and duration for a project.

Filter the data to display attributes that are more relevant to your project.  Popular filters include: programming language and team size.
