Study Notes
Implementing Tasks
- Purchase of new equipment
- Appointment of new employees
- Training of employees
- Planning and design of physical layout
- Coding
- Testing
- Design security measures and safeguards
- Create a disaster recovery plan
Request for Proposal
- A written document with detailed specifications used for bidding
- Contains detailed functional, technical, and business requirements information
- Compares different bids
- Convenient to use a single vendor to supply all components
- Consider that the vendor might not have knowledge for all areas of the business
Implementation Alternatives
- Insourcing: Organisation's team develops the system internally
- Self-sourcing: End-users design their own system with minimum or no input from IT
- Outsourcing: Organisation appoints an external supplier or consultant who specialises in development services
Implementation Methods
- Parallel: Old and new systems run simultaneously for a short time to ensure the new system works
- Phased-in-phased-out: Each module is phased in and the old one phased out until the whole system is operational
- Plunge: Stop the old system and start using the new one
- Pilot: New system is introduced to a limited area of organisation, and if it functions correctly, it is implemented in the rest of the organisation
Planning Questions
- Why is the system being developed?
- Who are the current and future users of the system?
- Is the system new, an upgrade, or an extension of the current system?
- Which functional areas (departments) are going to use the system?
Needs Analysis
- Information to be considered by the analyst includes:
- Organisation's strategic goals
- How the proposed system will support these goals
- Factors critical for the success of the proposed system
- Criteria for evaluating the proposed system
Task Force
- Should have representatives from different departments, including IT, systems analysts, technical advisors, and top management
- Joint program design is a collective activity of task force members
- Structured workshop where everyone comes together to develop the program
- Result is a final document containing definitions of the planned system
User Feedback
- Users should understand the 4 W's:
- Why is the system being designed?
- Who is going to use the system?
- When will the system be operational?
- What kind of capabilities will the system provide
