Lecture 19 — Production, Production Planning & Production Control

Production: the overall process of combining material and immaterial inputs (land, labor, capital, enterprise, management, etc.) to create outputs (goods and services) that have value and utility.
Manufacturing: a subset of production; the tangible activity of converting raw materials into finished goods (often high-volume, machine-and-labor centric).
Production planning: a pre-production function that matches production capacity to market demand in a feasible way.
Production control: monitoring and controlling the production/operation to ensure plans are implemented and organizational performance is met.

Scope: manufacturing = transforming raw materials into goods; production = everything around that transformation (planning, logistics, services).
Inputs: manufacturing primarily needs men and machines; production includes manpower, land, capital, management, services, etc.
Tangibility: manufacturing outputs are typically tangible goods; production outputs can be goods and/or services (tangible + intangible).
Conclusion: manufacturing is a component of the broader production system.

Purpose: forecast and meet market demand while maximizing output in a feasible, cost-effective manner.

Core objectives:

Meet quality, speed, efficiency, and cost targets.
Best possible utilization of available resources (avoid under- or over-investment in equipment).
Meet delivery schedules and customer demand.
Support worker welfare (earnings, incentives) and management preparedness for disruptions.
Minimize operating cost while maintaining planned efficiency.

The plan must answer four central questions:

Facility location and material handling
Capacity planning (how much production capacity is required for demand, including export vs domestic)
Procedure and process planning (clear job definitions, workflow and SOPs)
Job design and resource allocation (human resources, machines, tooling)
Manufacturing plan design and control of product quality
Product service and aftercare considerations
Facility and layout design
Financial planning and milestone/cost tracking

Determine targets based on past experience and constraints (budget, manpower, production capacity).
Collect and interpret information:
- Raw material availability
- Market/technology trends and standards (need for adoption of new tech)
- Sales forecasts and demand projections
Develop a detailed plan:
- Decide batch size, specific procedures, process steps, and lead times
- Define production rates, number of machines/printers/operators needed, and packaging/packaging rates
Put the plan into operation — execute production according to the plan.
Follow-up and monitor execution continuously.
Control and correct deviations:
- Detect delays, quality problems, machine breakdowns and apply corrective actions
Financial projection and milestone tracking:
- Create cost sheets, forecast demand across future years, set key milestones and track costs

Objective: rapid, ergonomic face shield for frontline healthcare workers during the pandemic.

Development and testing:

Prototyping and design optimization across 10+ iterations.
Manufacturing method: single-unit 3D printed frames + separate transparent sheets + simple assembly (snap-in grips).
Short- and long-term testing: student wear tests and simulated “pseudo-hospital” beta testing with volunteers for hours of real use.
Customer feedback collection and design refinements (e.g., increased number of grips, resized frame for comfort).

Production planning and execution:

Lab setup: CAD design and a row of 3D printers for production.
Packaging: poly bags including frame, sheet, instruction sheet, logo/contact info.
Initial production volumes: ~200 frames/week, target 300–500/week depending on printer capacity.
Scaling challenges: at 500/week, producing 10,000 units would take ~20 weeks (about 5 months), which may be slow during urgent demand surges.
Quality control: dedicated person inspecting prints and rejecting defective parts.
Distribution: shipped in batches to hospitals/NGOs for onward distribution; funded through CSR and other funds.

Outcome and lessons from Covlock:

Donated ~10,000 shields to hospitals.
Practical lessons in rapid prototyping, beta testing, scaling limits of additive manufacturing, packaging and logistics.

Definition: the continuous activity of monitoring and controlling production operations to ensure plans are met.

Role:

Production planning must be tied to realistic capacity and financial constraints.
Early-stage user testing and iterative prototyping catch usability issues before scale-up.
Scaling from prototypes (3D printing) to volume manufacture requires realistic assessment of per-unit production rate and lead time; additive manufacturing has throughput limits.
Contingency planning (backup machines, spare capacity) is essential to avoid catastrophic downtime.
Cross-functional coordination (design, prototyping, production engineering, logistics, finance) is required for successful execution.
