2 weeks work in 2 days

The software is late to test and needs to be sorted in 2 days and not the original 10. Something needs to give in order for the work to be completed on time and what is it? The example that I heard from a man 40 years in testing is this. If a 2 litre jug is the amount of work needed and a glass is the amount of time we have start pouring. It doesnt matter how much water you pour the water wont all fit in the glass.

With the testing what is needed is a test case, documenting what we are aiming at doing. If the time available is changed then the prioritization within the test case can be quickly utilised and the work done can be de-scoped. If we have tests that range from risk 1 - 9 then it might be that within 2 days we can only run the risk 9 tests, this can then be agreed as an acceptable approach with the stakeholders. It will mean that an informed decision can be made on whether the coverage provided is acceptable or not.
