ISDP Framework Components

Methodologies Employed

Selecting the right methodology is foundational to the success of an ISDP. The most commonly employed methodologies are Waterfall, Agile, and Hybrid Approaches.

Waterfall

• Phases: Divided into distinct phases like requirements, design, implementation, testing, deployment, and maintenance.
• Pros and Cons:
  • Pros: Easy to manage, clear milestones.
  • Cons: Inflexible, not suitable for projects with changing requirements.

Agile

• Sprints: Work is divided into time-boxed iterations called sprints.
• Pros and Cons:
  • Pros: Highly flexible, allows for changing requirements.
  • Cons: Difficult to manage larger projects, scope creep.

Hybrid Approaches

• Combination: Merges elements of both Agile and Waterfall.
• Application Scenarios: Best when the project has fixed requirements but also needs some room for flexibility.

Methodology	Flexibility	Suitability
Waterfall	Low	Large, well-defined projects
Agile	High	Small to medium projects with dynamic requirements
Hybrid	Medium	Projects that require a balance of both

Key Elements

An ISDP is composed of several key elements, each contributing to the project’s ultimate success. These include Requirements Gathering, System Design, Implementation, Testing, Deployment, and Maintenance.
