It enables calibration of effort estimation methods that relay on use-case-based functional size measurement (FSM), such as Use Case Points, Transactions, and TTPoints.

The question arises whether all of these components are important from the effort estimation point of view. Objective: This paper investigates the construction of UCP in order to find possible ways of simplifying it. Method: The cross-validation procedure was used to compare the accuracy of the different variants of UCP (with and without the investigated simplifications). The analysis was based on data derived from a set of 14 projects for which effort ranged from 277 to 3593 man-hours. In addition, the factor analysis was performed to investigate the possibility of reducing the number of adjustment factors. Results: The two variants of UCP - with and without unadjusted actor weights (UAW) provided similar prediction accuracy. In addition, a minor influence of the adjustment factors on the accuracy of UCP was observed. The results of the factor analysis indicated that the number of adjustment factors could be reduced from 21 to 6 (2 environmental factors and 4 technical complexity factors). Another observation was made that the variants of UCP calculated based on steps were slightly more accurate than the variants calculated based on transactions. Finally, a recently proposed use-case-based size metric TTPoints provided better accuracy than any of the investigated variants of UCP. Conclusion: The observation in this study was that the UCP method could be simplified by rejecting UAW; calculating UCP based on steps instead of transactions; or just counting the total number of steps in use cases. Moreover, two recently proposed use-case-based size metrics Transactions and TTPoints could be used as an alternative to UCP to estimate effort at the early stages of software development.

It is based on two main inputs which are actors complexity, measured based on the interface actor uses to communicate with the system; and use-case complexity measured in the number of so-called transactions in use-case scenarios. Here, I would like to present you basic information about the original method proposed by Karner.

In my opinion it could be especially valuable for beginners in that field, however advanced users will also find plenty of valuable information there.

The rapid popularity growth stimulated many different approaches for their presentation and writing styles. Unfortunately, this variability makes automatic processing of use cases very difficult. This problem might be mitigated by the use of transaction concept, which is defined as an atomic part of the use case scenario. In this paper we present approach to the automatic transaction discovery in the textual use cases, through the NLP analysis. The proposed solution was implemented as a prototype tool UCTD and preliminarily verified in a case study.  No publisher mochodek effort estimation use case points requirements engineering natural language processing use cases use-case transaction 2009-09-08T06:25:23Z Inproceedings Reference
