....at a given time. The more information available regarding the states of the process the better the controllability level. The software development process has been modeled using different techniques ranging from finite state machine, process language, and simulation based models among others [1, 2, 3, 4, 5, 6]. Recently, a state variable approach has also been used to model and control the system test phase of the Software Test Process (STP) 7, 8] A state variable is a set of differential equations organized in a matrix format allowing the prediction and control of the states of a process. This ....

....five different paradigms: 1. Programming models, e.g. APPL A, PADM PML. 2. Functional models, e.g. HFSP. 3. Petri net (and state transition) models, e.g. SPADE 1, Melmac [42] and ProcessWeaver [29] 4. Plan based models, e.g. GRAPPLE [44] 5. Quantitative models, e.g. system dynamics [1]. Another classification is proposed in [53] where six different classes are identified: graphical, net oriented, procedural, object oriented, rule based, and multi paradigms. In general, the issue is still debated in the community (see the evaluation section later on) 3.2.2 Modeling of ....

....the model with data from a large industrial project supplied by Razor sh Corporation. The STP is one of the nal phases of the software development process (SDP) studied quite extensively [2] The work described here is related, among others, to the FEAST Project[9] to System Project Dynamics [1], and to Statistical Process Control [5] although these endeavors do not focus in the STP, but rather consider the entire SDP. State models [11, 3] are a special type of di erential equation model well suitable to modeling processes and to control system analysis, design and optimization [3, 10, ....

....we have two state variables: the remaining errors (r) and the error reduction velocity (v e ) It is easy to de ne the rst derivative of the state variables as a function of the state variables. We have the following relation: r = wf s c r The force F d represents a disturbance [1] during the test phase and feedback will be used to minimize this disturbance and produce the expected output in the appropriated time, if this task is feasible. That is, suppose a hard disk failure prevents the test to be conducted for two days. This disturbance will cause a decreasing in the ....

Published examples of SD applications in software development cover a variety of issues such as software project management [10 12], the impact of process improvements on cycle time [13] concurrent software engineering [14] effects of software quality improvement activities [15 16] software reliability management [17] software maintenance [18] and software evolution [19] This paper presents a simulation model that was ....

.... simplicity of Brooks Law may have elevated it into a kind of managerial mantra that may even be misleading [10] Contrary to this oversymplifying form of Brooks Law, a systems thinking perspective suggests that adding the right people to a late project early enough can even save the project [1]. Adding the right people to a late project early enough can save a project. If managers fallaciously apply Brooks Law and do not introduce appropriately qualified new staff into the project team early enough, they probably do commit an error. This is a common error of judgement among managers ....

....of underlying structure [11] Systems thinking is, according to Richmond, a paradigm and a learning method. System dynamics is defined as the application of feedback control systems principles and techniques to modeling, analyzing, and understanding the dynamic behavior of complex systems [2]. System dynamics modeling (SDM) was developed in the late 1950 s at M.I.T. SDM is based on cause effect relationships that are observable in a real system. These cause effect relationships constantly interact while the computer model is being executed, thus the dynamic interactions of the system ....

....of the SD simulation has two aspects: an intellectual one, consisting of a better understanding of the process and a practical one, consisting of prediction, tracking, and mining. SDM was applied to the software development process for the first time by Tarek Abdel Hamid and Stuart Madnick [2]. Their model captures the managerial aspects of a waterfall software life cycle. It was the starting point for many subsequent models of the entire process [15] 14] or parts of it [5] and [9] that have been successfully used for resource management [8] 13] process reengineering [4] project ....

....project managers can only add new people a few times throughout the entire project life cycle. The two unrealistic assumptions lead to their conclu sion that adding more people to a late project always causes it to become more costly but does not always cause it to be completed later ( 1] [2]) The increase in the cost of the project is caused by the increased training and communication overhead, which, in effect, decreases the productivity of the average team member and thus increases the project s man day requirements. Only when the incurred training and communication overheads ....

....with minor variations in equation formulations and parameter values. Next, we want to know if the CSE SD model is capable of generating project behavior similar to those reported in the literature. To conduct the test, we calibrate CSE SD against the data reported in Abdel Hamid and Madnick [2]. Our purpose is twofold: 1) to use their data and simulated result as a reference and (2) to compare our simulated results with theirs. We compare seven key project measures, namely, perceived job size, perceived project cost, cumulative units developed, cumulative units tested, scheduled ....
