Planning for a New System

A new system can bring numerous benefits to different users within an organisation:

Improved Efficiency: Streamlined processes can save time and reduce errors.
Better User Experience: Modern interfaces and intuitive design can make work more enjoyable and productive.
Enhanced Capacity and Scaling: New systems often allow for growth and increased workloads.
Cost Efficiency: While there may be upfront costs, new systems often lead to long-term savings.
Future Proofing / Competitive Advantage: Staying up-to-date with technology can give organisations an edge over competitors.
Better Compliance: New systems can help ensure adherence to regulations and industry standards.

Example

Imagine a small retail business upgrading from a manual inventory system to a digital one. This new system could provide:

Real-time inventory tracking
Improved accuracy
Enhanced reporting and analytics

and so on.

The Importance of Planning

Aligns with Organisational Goals: Ensures the system supports strategic objectives.
Identifies Risks: Anticipates potential challenges and mitigates them early.
Ensures Stakeholder Buy-In: Involves users and stakeholders to foster ownership and acceptance.

Note

Neglecting user input during planning can lead to a system that doesn't meet their needs, resulting in low adoption and high resistance.

Primary Stages in System Life Cycle

We can outline five stages:

Analysis - understanding the context (what the users need and how the current system works)
Design - making detailed plans for software and hardware components
