If we have a model like the one above, we can use something like the function point method and object point method. Here we try to estimate the amount of effort required to build a story or a screen with its accompanying functionality.

To do this, we look at each story and consider the functions contained in it. We then try to categorize what sort of function this is. We can nd information that estimates the amount of effort each category of function might require; this data is collected in industrial organizations, and some of it is published. We include some examples here. It is a good practice to try to measure your own efforts for these functions to see if they agree with the estimates and to inform future projects.

We need to ask some basic questions at the start of the project and also at suitable review points during the project: How long will it take What resources will it need How expensive will it be The standard approach is to use the techniques of software measurement, however, there are overheads involved in doing this, and we need to consider to what extent it is worth doing this. During the course of projects, we measure the following parameters: Lines of code (loc) produced over the timescale Number of observed defects over the timescale Number of person-hours worked over the timescale Amount of time spent on debugging over the timescale Amount of time spent on requirements over the timescale Amount of time spent on design/speci cation/analysis over the timescale Amount of time spent on writing documentation over the timescale Amount of time spent on testing/review over the timescale And so forth These are all measures of production volume, product quality, and effort. If we have some previous experience and data of this type for old and similar projects, we may be able to estimate the effort and time needed for the new project. In many cases, the type of project is of a new type, the technology being used may be unfamiliar, and the programmers may also be different to previous projects. This it is a dif cult issue to decide what is best. From the time sheets and documentation produced, we should be able to nd the following for the completed project: Lines of code (loc) per person-month (pm) Cost per 1000 lines of code (kloc) Errors per kloc Defects per kloc

Pages of documentation per kloc Cost per page of documentation Number of requirements Average kloc per requirement If we have this data, then we might be able to estimate what the next project will need in terms of people and time. But different types of project will require different amounts of effort, so we need to collect information about the type of project: Product functionality product quality product complexity product reliability requirements And so forth These are not always easy to measure, unlike the rst set of measures. We need to describe the software being built on the basis of the requirements in order to estimate the resources needed. There are several techniques, none of which are very precise. If the new project is very similar to the previous ones, things are much simpler. If it is a completely new type of project, perhaps involving a new technology, then it is much more dif cult. We can pick out a few simple principles from function point analysis that can be helpful as long as they do not become too time consuming. Function point analysis (FPA) was developed by Albrecht (1979) for business information systems development. 1 For each requirement/story, we decide if it is one of input, output, inquiry, reference le, database. 2 Assign a weight to each requirement: simple, average, complex. 3 Consider other in uencing factors (reusability, adaptability) and weigh them according to a suitable scale. This is, to an extent, guesswork, but if we have an idea of which requirements are hard to implement and which are easier, it will help us to plan. Assigning these attributes needs some experience, but then what Ideally there is a database of previous similar projects that can be analyzed and conclusions on the effort required to complete a story made.
