1 - Introduction to software development

Difference between Individual & Professional software development

Individual development is developed by individuals for personal needs and mainly consider the coding and technical aspects.

\
Professional development is developed by a team for business needs and considers all aspects (technical, non-technical and global aspects) and considering the full software development life cycle stages.

Software Characteristics

• Functionality or features

• Performance

• Maintainability

• Dependability

• Usability

Model driven software development

An approach to software development where models are the primary source for analysing, designing, constructing, deploying and maintaining a system.

Model

A formal specification of the function, structure and behaviour of a system within a given context from a specific POV. This is generally represented by a combination of drawings, text with formal notation.

Traditional Software development Process

This method has linear stages and is best for simple unchanging projects AKA waterfall method.

1. Planning & analysis

2. Architecture & design

3. Implementation & testing

4. Deployment & operations

5. Maintenance & evolution

Agile software development

This method is a continuous cycle of development where users have high involvement in the process to produce a flexible and continuous evolution.

1. Requirements

2. Plan

3. Design

4. Develop

5. Release

6. Monitor

Agile values

• Individuals and Interactions over processes and tools

• Working software over documentation

• Customer collaboration over contract negotiation

• Responding to change over following a plan

Software development projects

projects consist of a Project stack which we use to create an Application stack

A project stack is a collection of tools which will allow the team to manage the project.

A application stack consists of the different applications the team would need to complete the project.
