The most straightforward way to estimate project cost would be: Project Resource Cost x Project time = Project cost Unfortunately, it is not that easy. 7pace is a time-tracking extension for Azure DevOps and Github. be done in twelve weeks of development effortand whether my team will have control in the project to realistically manage towards that goal. Moreover, you may need to do some analogy based techniques for similar components or functions developed before or maybe a similar project to ensure that you are on the correct path. FPA classifies the complexity of each function type as below, The next step is to relate our functions to these complexity levels and apply the weightings for each one, for example, let us assume that we have the following outcome from our functional points. The project's complexity. So each story will be 1 point for development and 4 . As software developers, were estimating when there is uncertainty: Not only are those things not fully known, some of them are unknowable.

Step one is to decompose your main task into several or many sub-tasks and estimate each separately. You can do the same for all the software components or functions and this will lead us to the next step of calculating the unadjusted function points by summation of all weights, Unadjusted Function Points (UFP) = (n EI) + (n EO) + (n EQ) + (n ILF) + (n EIF). Assume the total cost for the project is given. In this step, the actual estimation will be done for each component alone, and I will illustrate more about how you will do that using the techniques mentioned above, this will be illustrated in 8 steps in details below.
