Hi All,
Please can you help me in preparing an estimation guidelines.
For Oracle Forms and reports, i need to define criteria based on which any development piece of work can be divided into complexity of simple, medium, complex, very complex.

Also the rough estimate for that piece of work.

Please can any one send me if you have already have a similar guidelines.

Thanks in advance.

Regards,
Gitanjali

Sorry that I have been so long in replying. Have you solved your problem?

As a rule of thumb I use: simple - 1 day, medium - 1 week, complex - 1 month, very complex - 1 year. This includes specification finalisation, database and form development, system testing, user testing, integration testing, deployment, user guide creation, warranty.

Simple - one table, it has data, the user knows what they want to see and has supplied a layout that it trivial.

Medium - more than one table with defined relationships, data exists, the user knows what they want to see and has supplied a layout that has, at most, one complex structure.

Complex - numerous tables, no data (developer must create own data but with no guarantee that the data is what will ultimately be available), the user is not certain of what they want to see but will know what they want when they see it, numerous 'breaks' and 'pagination', plus running totals and some computation.

Very complex - numerous tables, no or little inter-relationship, as above - no data (developer must create own data but with no guarantee that the data is what will ultimately be available), as above - the user is not certain of what they want to see but will know what they want when they see it, numerous non-standard 'breaks' and suppressed headers, non-standard computation and numbering, possible requirement for temporary tables to be created and populated plus procedures to perform some of these actions, also requirement to display more characters than are available on a line so that 'logic' must be applied for each page to 'move' the columns around to get results onto the page.

By the lack of response, I don't think anyone else has a better method that I suggested.

I think you will just have to work on a few forms yourself and keep measurements of how long they took to complete.
