PRODUCTION PLANNING FOR MANUFACTURERS

Build a Production Plan Your Team Can Actually Use.

A production schedule is only useful when the assumptions behind it are reliable.

Driscoll Associates helps manufacturers improve the processes, ERP configuration, data, material planning, capacity information, scheduling, and reporting behind production planning.

When one of those inputs is wrong, the entire plan can change.

The goal is not simply to create a schedule.

The goal is to create a plan the operation has a reasonable chance of executing.

  • Do we have the material?
  • Do we have the capacity?
  • Are the routings accurate?
  • What is already in progress?
  • Which customer orders have priority?

Does This Sound Familiar?

“We Have a Schedule. We Just Don't Trust It.”

Production planning problems often look like:

0/ 10

When the production plan becomes unreliable, teams stop following it. Then planning becomes firefighting.

Why Production Planning Matters

Production Planning Connects Demand to Execution.

A manufacturing plan sits between several parts of the business.

If those areas are disconnected, the schedule may look complete while the operation remains unprepared.

What Good Production Planning Should Answer

A Useful Plan Should Help the Business Answer:

  • WHAT NEEDS TO BE PRODUCED?

    Based on customer demand, forecast, replenishment, or internal requirements.

  • HOW MUCH?

    The correct quantity based on demand and inventory.

  • WHEN?

    Based on required dates, lead times, and capacity.

  • WITH WHAT MATERIAL?

    Required components and current availability.

  • USING WHICH RESOURCES?

    Machines, work centers, labor, and available time.

  • IN WHAT SEQUENCE?

    Based on priorities, dependencies, setup, and constraints.

  • WHAT IS AT RISK?

    Shortages, overloaded resources, delayed operations, or unrealistic due dates.

Production planning should support decisions⁠—not simply generate work orders.

Common Root Causes

A Bad Schedule Is Often the Symptom.

The underlying issue may be:

The first task is to understand why the plan keeps changing.

01

MATERIAL DATA

  • Incorrect inventory
  • Late purchasing
  • Poor lead times
  • Incomplete BOMs

  1. MATERIAL DATA

    • Incorrect inventory
    • Late purchasing
    • Poor lead times
    • Incomplete BOMs

  2. ROUTINGS

    • Outdated operation times
    • Wrong work centers
    • Missing setup time
    • Poor sequencing

  3. CAPACITY

    • Unrealistic available hours
    • Unplanned downtime
    • Incorrect labor assumptions

  4. DEMAND

    • Changing priorities
    • Poor forecast inputs
    • Unclear customer commitments

  5. PROCESS

    • Manual scheduling
    • Weak planning discipline
    • Unclear ownership
    • Too many exceptions

  6. ERP CONFIGURATION

    • Incorrect planning parameters
    • Weak MRP settings
    • Poor calendar setup
    • Misaligned replenishment rules

How Driscoll Approaches Production Planning

Start With How Planning Actually Works Today.

Driscoll may review:

  • Demand inputs
  • Planning processes
  • MRP setup
  • Bills of material
  • Routings
  • Work centers
  • Capacity assumptions
  • Production calendars
  • Material availability
  • Purchasing signals
  • Work-in-progress
  • Priority rules
  • Shop-floor reporting
  • Production KPIs
  • ERP configuration
  • Spreadsheet dependencies

The objective is to understand:

  • What is driving the current schedule?
  • Which assumptions are unreliable?
  • Where is the process breaking down?
  • What needs to change first?

Production Planning Assessment

Understand the Planning Gaps Before Rebuilding the Schedule.

Depending on the engagement, a planning assessment may review:

  1. 01

    DEMAND

    Are customer requirements and forecast inputs clear?

  2. 02

    MATERIAL

    Does the plan reflect actual material availability?

  3. 03

    CAPACITY

    Are available hours and constraints realistic?

  4. 04

    ROUTINGS

    Do production standards reflect how work is actually performed?

  5. 05

    PRIORITIES

    Are jobs sequenced consistently?

  6. 06

    EXECUTION

    Does shop-floor activity update the plan quickly enough?

  7. 07

    REPORTING

    Can planners identify exceptions without rebuilding reports manually?

Potential Deliverables May Include:
  • Current-state findings
  • Root-cause observations
  • Planning-process recommendations
  • ERP configuration recommendations
  • Data-quality priorities
  • Capacity-model recommendations
  • Reporting gaps
  • Prioritized next steps

Deliverables depend on the agreed engagement.

MRP & Material Requirements

A Production Plan Cannot Ignore Material.

MRP should help connect:

MRP
  • Demand
  • Bills of Material
  • Current Inventory
  • Open Purchase Orders
  • Existing Production
  • Lead Times

to determine what material is required and when.

A Useful Material Plan Helps Answer:

  • What is missing?
  • How much is missing?
  • When is it needed?
  • Is it already on order?
  • Which production orders depend on it?
The objective:

Identify material problems before they become production delays.

Inventory + Production Planning

Inventory Accuracy Is a Planning Requirement.

If the ERP says material is available when it is not, the production schedule may be impossible before the first operation begins.

Production planning depends on:

  • Accurate on-hand inventory
  • Correct allocations
  • Reliable locations
  • Timely receipts
  • Accurate production issues
  • Accurate production completions
  • Proper scrap reporting

Better planning starts with material information the business can trust.

Capacity Planning

Demand Does Not Automatically Create Capacity.

A production plan should consider whether the required resources are actually available.

Capacity Planning Helps Answer:

  • Which resources are overloaded?
  • Where is capacity available?
  • What happens if a job moves?
  • Can the requested date realistically be achieved?

Capacity May Depend On:

  • Work centers
  • Machines
  • Labor
  • Shift calendars
  • Setup time
  • Run time
  • Maintenance
  • Overtime
  • Planned downtime
  • Current WIP

A schedule should reflect operational constraints⁠—not ideal conditions.

Routing & Standard-Time Accuracy

The Schedule Is Only as Good as the Standards Behind It.

A routing may define:

  • Operations

  • Sequence

  • Work center

  • Setup time

  • Run time

  • Labor requirements

  • Outside processing

  • Better planning begins with better production data.

If those assumptions are outdated, the schedule may continually overestimate or underestimate what can be completed.

Driscoll May Help Review:

  • Routing structure
  • Standard times
  • Work-center assignments
  • Setup assumptions
  • Planned vs. actual performance

Production Scheduling

Turn the Plan Into an Executable Sequence.

Scheduling determines how production requirements are translated into actual work.

A useful schedule should account for:

  • Due dates
  • Material availability
  • Capacity
  • Work-center load
  • Priorities
  • Dependencies
  • Setup
  • Current WIP
  • Customer commitments

The objective is not a perfect schedule.

It is a schedule that helps teams make better decisions as conditions change.

The schedule should help answer:
  1. What should run next?
  2. Where?
  3. When?
  4. What is blocked?
  5. What changed?
  6. What is the impact?

Shop-Floor Feedback

Planning Improves When Execution Feeds the Plan.

If actual production information reaches the system too late, the next schedule is built on yesterday's assumptions.

Useful feedback may include:

  • Operation start
  • Operation completion
  • Quantity completed
  • Scrap
  • Labor
  • Machine time
  • Material usage
  • Delay reasons
  • Work-order status

Planned vs. actual data helps improve:

  • Routings
  • Capacity
  • Lead times
  • Costing
  • Future schedules

Today's production should improve tomorrow's plan.

Work-in-Progress Visibility

Know What Is Actually Happening Between Release and Completion.

Better WIP visibility can help planners understand:

  • Where is the job?
  • What is blocking it?
  • What operation is next?
  • Which orders are at risk?
WIP can become difficult to manage when jobs are:
Started but not completed
Waiting on material
Waiting on another operation
Delayed at a work center
Partially completed
Missing clear status

WIP should provide operational context⁠—not become a black box.

Production + Purchasing

The Schedule and Purchase Plan Should Tell the Same Story.

Purchasing needs visibility into:

  • Required material
  • Required dates
  • Current inventory
  • Open purchase orders
  • Supplier lead times
  • Production priorities

Without that alignment, buyers spend more time expediting.

Better production planning helps purchasing move from:

“What are we short today?”

to

“What will production need next?”

Production + Customer Commitments

A Customer Date Should Reflect Operational Reality.

Better planning can support more informed answers to:

  • Can we make it?
  • When can we make it?
  • What could delay it?
Sales needs enough production visibility to understand:
  • Material availability
  • Current backlog
  • Capacity
  • Production lead time
  • Existing commitments

Reliable customer commitments begin with better operational information.

Production + Cost

Schedule Accuracy and Cost Accuracy Share the Same Data.

  • Routings.
  • Labor standards.
  • Machine time.
  • Material usage.
  • Scrap.
  • Production quantity.

These inputs affect both:

SCHEDULE

How long should the work take?

and

COST

What should the work cost?

When production standards are wrong, planning and costing can both be distorted.

Explore Schedule & Cost Accuracy

Reporting & Production KPIs

Give Planners Visibility Into the Exceptions.

Relevant production measures may include:

  • Schedule adherence

  • On-time completion

  • Planned vs. actual hours

  • Work-center utilization

  • WIP

  • Throughput

  • Material shortages

  • Production lead time

  • Scrap

  • Backlog

The goal is not to create more dashboards.It is to help the team see where attention is needed.

Production + Business Intelligence

Move From “What Happened?” to “Why?”

Example:

Schedule Adherence Dropped
Which work center?
Which jobs?
  • Material problem?
  • Capacity problem?
  • Routing problem?
  • Priority change?

Business intelligence can help connect production performance with inventory, purchasing, cost, and customer demand.

Production + Automation

Reduce Manual Monitoring Where Appropriate.

Potential automation opportunities may include:

  • Shortage alerts
  • Late-order notifications
  • Schedule exceptions
  • Priority changes
  • Production status updates
  • Management reporting
  • Purchasing triggers

Automation should support planning discipline.It should not compensate for unreliable planning data.

Production + AI

AI Can Help Prioritize the Exceptions.

Once production data is reliable, AI may support areas such as:

  • Schedule-risk summaries
  • Material-shortage prioritization
  • Capacity-risk analysis
  • Production-performance summaries
  • Natural-language production queries
Example Questions:
  • “Which production orders are most likely to miss their due dates?”
  • “Which work centers are creating the largest schedule risk?”
  • “Which material shortages affect the greatest number of jobs?”

AI can help surface issues.The underlying process still needs to be sound.

Common Questions

Production planning is the process of determining what needs to be produced, how much, when it should be produced, what materials are required, and what resources are needed to meet demand.

How Production Planning Connects to Other Solutions

Production Does Not Operate Alone.

Engagement Starting Point

Start With Where the Production Plan Is Breaking Down.

You do not need to know whether the solution is:

  • MRP configuration.
  • Better routing data.
  • Capacity planning.
  • Inventory improvement.
  • Shop-floor reporting.
  • Process redesign.
  • Or a broader ERP issue.

Start with what your planners and production team are experiencing.

Driscoll can help identify the appropriate next engagement.

Detailed assessments, roadmaps, implementation, and optimization work are separately scoped.
