Operations Strategy: Operations Planning (Copy)
9.3 Operations Strategy
9.3.5 Operations Planning
1. Need for Planning Operations
- Operations planning ensures that resources, time, and processes are organised efficiently.
- Helps coordinate activities, reduce costs, and meet deadlines.
- Allows managers to identify risks and plan contingencies.
- Ensures smooth workflow between departments and employees.
- Supports quality and customer satisfaction by reducing delays and errors.
2. Network Diagrams as Tools to Plan Operations
- Network diagrams visually represent all tasks in a project and their dependencies.
- Useful for:
- Scheduling activities
- Managing resources
- Identifying critical tasks
- Planning project timelines
3. Main Elements of a Network Diagram
| Element | Description / Example |
|---|---|
| Activities | Tasks or work items that need to be completed (e.g., assembling a product) |
| Dummy activities | Activities used to show dependencies but do not consume time/resources |
| Nodes | Circles or boxes representing start/end points of activities or events |
4. Critical Path Analysis (CPA)
Purpose: Identify the minimum project duration and critical tasks.
Steps in CPA:
- Draw network diagram with activities and dependencies.
- Estimate duration of each activity.
- Identify critical path – the longest sequence of dependent activities.
- Calculate floats:
- Total float: How long an activity can be delayed without delaying the project
- Free float: How long an activity can be delayed without delaying the next activity
- Interpret results:
- Activities on the critical path are most crucial
- Non-critical activities have flexibility (float)
Use in project management:
- Helps allocate resources efficiently
- Identifies tasks that must not be delayed
- Enables better scheduling and contingency planning
5. Benefits of CPA
- Provides clear visual representation of project timeline
- Identifies critical activities to focus management attention
- Allows calculation of minimum project duration
- Supports resource allocation and monitoring
- Facilitates decision-making on adjustments
6. Limitations of CPA
- Can be complex for large projects with many activities
- Requires accurate estimation of durations
- Does not account for resource constraints automatically
- Updates needed if project changes occur frequently
- Cannot prevent delays but only helps plan for them
