Scheduled Production Plans

Role and Components of Scheduled Production Plans

What Is a Scheduled Production Plan?

A scheduled production plan is a comprehensive document that outlines all steps required to make a product, including the sequence of tasks, time estimates, required materials, tools and processes, quality checkpoints, and risk management measures.

It is developed before production begins, during the second diamond’s Plan and Manage phase, and is used as a live management tool throughout production.

Role of the Production Plan

• Ensures production is organised and efficient (no waiting for materials, no missed steps)
• Sets a timeline that keeps production on track
• Documents quality expectations at each stage
• Identifies safety risks before work begins, allowing control measures to be put in place
• Provides a record that supports evaluation and modification tracking
• Communicates the production process to others (teachers, assessors, clients)

Components

1. Timeline (Gantt chart or sequential table)
- Lists all production steps in logical sequence
- Estimates time for each step
- Identifies dependencies (step B cannot begin until step A is complete)
- Includes milestones and deadlines
- Distinguishes between machining/making time and waiting time (e.g. glue cure, paint dry)

2. Materials and Costings List
- Lists all materials required: type, specification (grade, thickness, dimensions), quantity
- Includes unit cost and total cost for each material
- Allows the designer to verify the product is achievable within budget
- May include a contingency allowance for waste or errors

3. Tools and Processes
- Lists all tools, machines, and processes for each step
- Includes settings and parameters where relevant (e.g. CNC feed rate, drill press speed)
- Allows advance preparation: tools set up, blades sharpened, jigs made

4. Risk Assessments and Safety Control Measures
For each significant hazard identified:
- Hazard: What can cause harm?
- Risk level: How likely and how severe?
- Control measure: What will eliminate or reduce the risk?

Control hierarchy (preferred in descending order):
1. Eliminate the hazard
2. Substitute with a safer alternative
3. Use engineering controls (guards, extraction)
4. Administrative controls (training, procedures)
5. Personal Protective Equipment (PPE)

5. Quality Measures
- What quality checks occur at each stage?
- What standards must be met before proceeding to the next step?
- How are checks documented?

Examples: check squareness before glue-up; test joint strength before surface finishing; verify dimensions against working drawing after each cut.

Using the Plan During Production

• Check off completed steps
• Record actual time vs estimated time
• Document modifications: what was changed, why, and what effect it had
• Note quality check results at each checkpoint

KEY TAKEAWAY: A production plan is a management tool, not just a schedule. It ensures safe, efficient, quality-controlled production and provides the evidence base for evaluation.

EXAM TIP: Know all five components and be able to explain the purpose of each. VCAA questions often ask specifically about risk assessment or quality measures — not just the timeline.
