3 Project Proposal

According to our additional information concerning "Use Cases and the Project Plan", we also estimated the amount of work for our project.
This includes the following steps:

Weighting Actors

In this first step, we took a look at the actors, which we've located earlier and allocated them to a certain group, depending on the weight of the actor, which can be simple, average or complex. Then we multiplied the number of actors in each group by a weighting factor (1, 2 or 3). The assumptions made above result in:

1 simple * 1 = 1
2 average * 2 = 4
3 complex * 3 = 9

Ammounting up to a total of: 14.


Weighting Use-Cases

This second step is similar to what we did with the actors. We again had 3 different groups in which the Use Cases were devided. The decision is based on how many transactions have to be carried out in a Use Case. The outcome of weighting the use-cases is:

3 simple * 5 = 15
4 average * 10 = 40
2 complex * 15 = 30

Ammounting up to a total of: 85.
Adding the actor's weights this gave a total of: 99 UUCP (unadjusted use case points).


Weighting Technical Factors

TCF = Technical complexity factor. This results in a TFactor of 44.5. Therefore our TCF = 0.6 + (0.01 * TFactor) = 1.045.


Weighting Environmental Factors

This result in an EFactor of 23.5. The environmental factor (EF) equals (1.4 + (-0.03 * 22)) giving a result of 0.695.


Conclusion

Use Case Points

Finally, we calculated the use case points (UCP).
UCP = UUCP * TCF * EF

In our case:
UCP = 99 * 1.045 * 0.695 = 71.9

Project Estimate

We used 20 man-hours per UCP giving us 1438 total man-hours which leads to about 36 weeks each 40 hours work.
As our team consists of 5 people, each will have about 8 weeks work plus 3 weeks for team issues. This gives about 11 weeks with 40 hours each. As we will invest about 20 hours a week for this project, our system should be ready within 22 weeks or 5 months.

Costs

Multiplying the total man-hours by 1.000,- ATS per hour, this gives a sum of about 1.4 Mio. ATS in total.
