Software Process simulation

Software Process simulation is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Software Process simulation rather than just read about it. In short: Software process simulation modelling: Like any simulation, software process simulation (SPS) is the numerical evaluation of a mathematical model that imitates the behavior of the software development process being modeled. SPS has the ability to model the dynamic nature of software development and handle the uncertainty and randomness inherent in it.

Key takeaways

Software Process simulation belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Software Process simulation to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Software Process simulation from memory before moving on to harder problems.

Reference excerpt

Software process simulation modelling: Like any simulation, software process simulation (SPS) is the numerical evaluation of a mathematical model that imitates the behavior of the software development process being modeled. SPS has the ability to model the dynamic nature of software development and handle the uncertainty and randomness inherent in it.

Uses of software process simulation Following main purposes have been proposed for SPS:

Support in operational project management (estimation, planning and control) Support for strategic management Tool for training and education for software project management and software development lifecycle (cf. and). Process improvement and technology adoption

How to do software process simulation Software process simulation starts with identifying a question that we want to answer. The question could be, for example, related to assessment of an alternative, incorporating a new practice in the software development process. Introducing such changes in the actual development process will be expensive and if the consequences of change are not positive the implications can be dire for the organization. Thus, through the use of simulation we attempt to get an initial assessment of such changes on the model instead of an active development project. Based on this problem description an appropriate scope of the process is chosen. A simulation approach is chosen to model the development process. Such a model is then calibrated using empirical data and then used to conduct simulation based investigations. A detailed description of each step in general can be found in Balci's work, and in particular for software process simulation a comprehensive overview can be found in Ali et al. In a recent initiative, by ACM special interest group on software engineering (SIGSOFT), a standard for assessing simulation-based scientific studies has been proposed.

Key venues Software process simulation has been an active research area for many decades some of the key venues include the International Conference on Software and Systems Process and its predecessor Workshop on Software Process Simulation Modeling (ProSim) from 1998 to 2004.

Worked examples

Example 1 — a first encounter with Software Process simulation

Start with the simplest possible case. Write down what Software Process simulation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Software Process simulation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Software Process simulation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Software Process simulation

In research: Software Process simulation appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Software Process simulation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Software Process simulation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Simulation, so understanding it makes those chapters shorter.
In everyday life: Look for Software Process simulation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Software Process simulation in simple terms?

Why does Software Process simulation matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Software Process simulation?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
