What does a Master Production Scheduler do?
A master production scheduler translates demand forecasts and customer orders into a time-phased plan for finished goods. This role balances available inventory against net requirements to set precise production quantities and timing. The scheduler coordinates these plans with material requirements planning systems to align supply with actual market needs.
- Determine gross demand by analyzing forecast data, confirmed customer orders, and interplant transfer requests. Subtract current inventory levels, open purchase orders, and existing work orders to compute exact net requirements for each item. Calculate the specific timing needed to meet these demands within the defined planning horizon.
- Run master production schedule generation cycles within enterprise resource planning software to create initial plans. Review system messages and exception reports to identify capacity conflicts or material shortages. Adjust planned order dates and quantities to resolve these exceptions while maintaining alignment with overall production goals.
- Coordinate the finalized master production schedule with downstream planning inputs used by material requirements planning systems. Validate bill of materials accuracy and inventory records to ensure correct component explosion. Generate planned orders and time-phased availability outputs such as Available to Promise indicators for sales teams.
How to hire a Master Production Scheduler on Upwork
Step 1: Post a job
Define your production planning needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing one.
- Specify the ERP or material planning systems the freelancer must use to generate master production schedules and manage net requirements.
- List required experience with bill of materials structures, inventory records, and calculating available to promise indicators for finished goods.
- Clarify whether the role involves full MPS generation or net-change updates based on fluctuating customer orders and forecast inputs.
Step 2: Evaluate candidates
Look for portfolios that demonstrate accurate time-phased scheduling and exception handling. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit quickly.
- Review examples of master production schedule statements that balance gross demand against available supply like purchase orders and work orders.
- Check for evidence of coordinating MPS outputs with downstream material requirements planning to prevent stockouts or excess inventory.
- Verify experience in freezing valid schedules and responding to system action messages during planning horizon refreshes.
Step 3: Interview your top choices
Discuss specific scenarios involving demand volatility and constraint management. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.
- Ask how they compute net requirements when subtracting current inventory and open purchase orders from forecasted gross demand.
- Question their approach to validating planned orders before releasing them to manufacturing or procurement teams.
- Explore their method for maintaining schedule stability while accommodating urgent customer order changes within the planning horizon.
Step 4: Agree on scope and begin work
Set clear milestones for schedule generation and validation cycles. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Define deliverables such as weekly MPS reports, updated net requirement calculations, and resolved exception messages from the planning system.
- Establish a review process for time-phased availability outputs to ensure alignment with sales forecasts and production capacity.
- Agree on frequency for running MPS generations and updating bill of materials data to reflect current engineering changes.
