The Four Decisions·03 / 04

Scheduling.

A feasible schedule respects demand dates, approved transitions, shared resources, and product-specific rates. A sequence that reduces changeovers may still create excess inventory or miss a customer commitment. Evaluate the complete tradeoff.

The bar

A feasible sequence with explicit transition, resource, inventory, and service assumptions.

If Anyone Can Move The Date, Nobody Owns The Plan

An operations leader put it in one line during a weekly review: if everybody has the ability to change the dates, we have no idea what we are driving toward, or how long it takes, or why it is late.

Sep 09

A Project Slot Is Not a Unit of Capacity

A project-count limit can protect attention, but it cannot show which resource is overloaded. Test the next commitment against its actual demands.

Sep 04

Date the Inputs Behind the Constraint Map

A constraint map may be newly formatted and still rely on an obsolete rate. Its usefulness depends on the inputs behind the decision, not the date on the cover.

Jun 09

Recheck Capacity When the Recipe Changes

Does a change to an existing recipe or process alter the capacity needed to serve the same demand?

Jun 01

Give Rework and Trials a Place on the Schedule

How should production planning reserve capacity for rework, retests, and qualification runs?

May 07

Give Each Product Family a Usable Capacity Rate

How should a scheduler combine different product rates without overstating available capacity?

May 05

Count One Changeover as One Elapsed Event

Are changeover averages measuring complete transitions or fragments of them?

Apr 22

Which Cold-Storage Capacity Is Actually Full?

Is the limiting cold-storage resource space, handling throughput, or the approved thermal operating envelope?

Apr 21

Price the Next SKU Against a Feasible Schedule

What incremental operating burden does a proposed SKU add to the actual order book?

Apr 15

Material Saved Is Not Automatically Capacity Recovered

When does reduced giveaway create extra units, and when does it only reduce material consumption?

Apr 04

Separate Required Hold Time from Waiting for a Decision

Which part of a quality hold can be shortened through better evidence and coverage without weakening release requirements?

Apr 01

Release the Hold, Then Schedule Its Return

How should cleared product or approved rework rejoin a schedule that has already advanced?

Mar 28

Size the Buffer for Work Already Committed

Can the available buffer absorb upstream output during packaging changeover and clear before the next stop?

Mar 24

Put the Freshness Clock on the Production Calendar

Which scheduling choice preserves the customer's required remaining life at delivery?

Mar 23

A New Package Needs an Approved Process Route

How should a container change enter a thermal-process capacity decision?

Mar 17

Give Staging Time a Lot-Level Record

Which product actually waits in staging, for how long, and under which conditions?

Mar 08

A Packaging Format Needs a Transition Cost

What does a new packaging format change about the next and previous production runs?

Mar 07

The Restart Clock Ends at Good Output

How much production is actually lost between cleaning completion and a stable approved restart?

Mar 07

Schedule the Resources That Sanitation Shares

Are simultaneous sanitation events delayed by shared resources rather than the individual procedures?

Mar 05

Put the Approved Allergen Transition in the Schedule

How should planning represent allergen requirements without inventing cleaning rules?

These four decisions are not made in isolation. A labor plan is a scheduling bet; an automation case is a sourcing assumption. The savings leak in the seams between them, and that is where the money is. Follow the consequence across the system, and price it, before calling the change a win.
