The presentation introduces software process models and specifically focuses on evolutionary software process models (ESPM), which are defined as iterative models that allow software engineers to develop increasingly complete versions of software. It highlights three main types of ESPM: incremental model, spiral model, and component assembly model, each with its own pros and cons. Additionally, the document compares these models with traditional linear process models like the waterfall and prototyping models.

- 1. Evolutionary Software Process Model Taha Shahid (Student643310) Semester 5 – Miss Samra
- 2. Objectives of this Presentation: • To give a small introduction of Software Process Model. • To describe Evolutionary SPM. • To describe following types of ESPM: – Incremental mode – Spiral model – Component assembling model
- 3. What is Software Process Model? A software process model is a standardized format for – Planning – Organizing, and – Running a development project.
- 4. How many models of SPM are there? Hundreds of different models exist and are used but following are the most important models: • Linear Process Models – Waterfall Model – Prototyping Model • Evolutionary Software Process Models – Incremental Model – Spiral Model – Component Assembly Model
- 5. What Evolutionary means? This word is derived from the word “Evolution”. Evolution (noun): A regular process in which something changes into a different and usually much better form. Modern example: An evolutionary process of Apple, from heavy Macs to smart iPhones.
- 7. Evolutionary Software Process Model Evolutionary software models are iterative. They are characterized in manner that enables the software engineers to develop increasingly more complete version of a software. In programming "iteration" means sequential access to objects. It is typically a cycle. Software engineers can follow this process model that has been clearly designed to put up a product that regularly complete over time.
- 8. How many categories are there of ESPM? The ESPM has been categorized into 3 types of models. 1. Incremental Model 2. Spiral Model 3. Component Assembly Model
- 9. 1 - Incremental Model
- 10. 1 - Incremental Model A model where the software specification, design, implementation and testing is broken down into a series of increments which are developed and delivered. Pros: Higher quality Cons: Needs good planning and design.
- 11. 2 - Splral Model?
- 12. 2 - Spiral Model Another evolutionary life cycle model that combines the linear nature of the Waterfall model and the iterative (repetitive) nature of the Prototyping model. The project life cycle is divided into phases, and each phase is executed in all of the iteration of the Spiral Model. Pros: More detailed processes for each phase. Cons: Costly Sometimes difficult to implement.
- 13. Inner cycles represent the early phases of requirement analysis along with prototyping. While outer spirals are progressively representative of the classic software life cycle.
- 14. 3 - Component Assembly Model
- 15. 3 - Component Assembly Model Component Assembly Model is just like the Prototype model, in which first a prototype is created according to the requirements of the customer. Thus, this is one of the most beneficial advantages of component assembly model as it saves lots of time during the software development program. Instead of searching for different codes and languages, the developers using this model opt for the available components and use them to make an efficient program.
