    Development Time Vs Testing Time

    Hi All
    If you are asked to give an estimate of timne required for testing the only input that you have is development time is 45 man months what should you say.The project is in MIcrosoft technology and database is SQL. Is there a thumb rule for this. I am talking about all kinds of testing leaving apart Usability testing.
    Let's get the response from the most experienced people on the forum.

    Re: Development Time Vs Testing Time

    My previous QA Director would always use the 50% rule. He'd say QA testing will take at least have the time development took.

    If the only input I have is that the development would take 45 man months, I'd say that the testing would take 33 man months.

    I'd also say that if a more accurate answer were needed, I'd need more input.

    Re: Development Time Vs Testing Time

    we use 40% time of development time. Always work for us. I think it depends of u have tools or not.

    My question is this: Where did they get the 45-month number from? However they came up with that number, you should use similar guidelines to come up with your number.

    I would also ask your development team for some sort feedback. Seeing as how they're developing the "application", they should have a rough guesstimate as to the complexity of the testing effort.

    Re: Development Time Vs Testing Time

    I am working for an organisation which takes care of outsourced testing requiements of the development companies.These are the inputs you get from the development companies in the initial dicussions and than they ask for cost. Another input that i have now is that there are 72 use cases in the project. What do you do. You can't be harsh and have to engage the client as well as keep the interst of your organisation by not underquoting the efforts.I am still looking for a thumb rule. What we have arrived is around 30-35% of the development effort should be put in testing. There are lot of factors on which you can guesstimate the efforts but at the EOD again all this depends on how good developers are?

    Re: Development Time Vs Testing Time

    It's safe to say that you don't have enough information to accurately quote the amount of testing time required. You need an idea of the scope of the project, the level of 'fit for use', an idea of the experience of the team, what tools are required and what the requirements of the project is.

    I've seen everything from 30% up to 60%. Obviously this is much too large to cover and to be expected to give an honest, accurate quotation. There's no sense in giving a quotation based on nothing. Guesstimates are not a way to do business. We are in the business of proving and fact, so a guess cannot be your foundation.
