Study Notes
Application Development
- A software lifecycle model is used to describe the different stages required to create a software product.
- The Waterfall method is like a one-way street, once a stage in the process is completed, you cannot go back to the previous stage.
- This method assumes that the project requirements are clearly defined and there is a shared understanding between the customer and project manager.
- Advantages of the Waterfall method:
- Provides a structured and meticulous approach to development.
- Suitable for large projects where requirements are stable.
- Useful for training junior programmers.
- Disadvantages of the Waterfall method:
- Difficult to accommodate changes in requirements.
- When is the Waterfall method best suited?
- When there are minimal anticipated changes to the project.
- When the budget is fixed.
- When the project is similar to a previous project completed by the team.
Agile Development
- Agile development is a more flexible method that involves iterative development cycles called sprints.
- The team is responsible for managing the development process and adapting to changes.
- Sprints: Short timeframes (usually 2-4 weeks) where a specific set of features are developed and delivered.
- Advantages of Agile Development:
- Cost-effective by minimizing unnecessary work and streamlining processes.
- Encourages collaboration within the team.
- Short lead times between prototypes and iterations, increasing flexibility.
- Disadvantages of Agile Development:
- Requires a strong team with high levels of collaboration.
- Not suitable for large teams.
- When is Agile Development best suited?
- For projects that can be broken down into smaller, manageable sprints.
- When the customer is involved in the process but does not require constant updates.
- For projects with limited budgets.
Database Application Development
- Applications that are built around a central database of information.
- Functions enable users to:
- Retrieve, sort
- Calculate
- Report on data.
Rapid Application Development (RAD)
- RAD is a fast-paced approach to software development focusing on rapid prototyping and iterative feedback.
- The goal is to build and deploy software quickly and adapt to changing requirements.
- Steps involved in RAD:
- Define Requirements
- Prototype Development
- Feedback Collection
- Finalization of Software
- Advantages of RAD:
- Promotes early involvement and feedback from customers.
- Fast development cycles.
- Minimizes risks and rework.
- Disadvantages of RAD:
- Limited scope, best for projects with well-defined requirements.
- Requires experienced developers who can make quick decisions.
Mobile Application Development
- Focuses on creating applications specifically for mobile devices.
- Design considerations are tailored for touch screens, mobile operating systems, and user interactions expected on smaller screens.
Business Process Application Development
- Focuses on creating applications that streamline business processes, such as:
- Approvals
- Routing
- Data integration
Business Process Automation (BPA)
- The use of technology to automate repetitive tasks or processes within a business.
- Aims to reduce manual effort and improve efficiency.
- Benefits of BPA:
- Increased efficiency
- Reduced errors
- Improved compliance
- Enhanced customer satisfaction
- Streamlined operations
- Stepping stone to digital transformation
- What business processes can be automated?
- High-volume tasks
- Tasks involving multiple people
- Time-sensitive tasks
- Processes with a significant impact on other systems or processes
- Processes that need audit trails for compliance.
