Study Notes

Executive Information Systems (EIS)

EIS systems provide summarized information from internal and external sources to support strategic decision-making for top-level executives.

Agile Methodology

Agile prioritizes flexibility, collaboration, and customer feedback, involving iterative development, frequent releases, and adaptability to changing requirements.
Scrum is a popular framework within the Agile approach.

Scrum Framework

Scrum is an agile framework for managing software development projects, emphasizing flexibility, collaboration, and continuous improvement.
Scrum promotes iterative development, where work is divided into small, manageable increments called "sprints," typically lasting 2-4 weeks.

Scrum Roles

Product Owner: Represents stakeholders, defines the product backlog, prioritizes features, and manages requirements.
Scrum Master: Facilitates the Scrum process, removes impediments, and ensures the team adheres to Scrum principles and practices.
Development Team: Self-organizing, cross-functional team responsible for delivering product increments within the sprints.

Scrum Process

Sprint Planning: Meeting where the team plans the work to be performed during the sprint.
Sprint Review: Scrum Team conducts a meeting to demonstrate the completed work to stakeholders and gather feedback.

Software Development Life Cycle

The 5 stages of software development life cycle are:
- Planning & Analysis: Gathering business requirements from clients or stakeholders.
- Define Requirements: Converting gathered information into clear requirements for the development team.
- Design: Creating the architecture and design of the application based on the requirements.
- Development: Writing the code and implementing the functionality of the application.
- Testing: Verifying the quality and functionality of the application and identifying and fixing any defects.

Advantages of Scrum

Flexibility and Adaptability: Scrum is highly adaptable to changing requirements and priorities.
Transparency and Visibility: Scrum provides transparency into the development process.
