How to set up a production planning system that reduces chaos

In most Indian manufacturing SMEs, production planning lives in one person's head — usually a senior operator or the production manager. When that person is absent, the plant runs reactively. When orders surge, priorities collide and promises are missed. A basic production planning system fixes this.

Production planning has three components: demand (what needs to be produced and when), capacity (what can you actually produce given your machines, manpower, and materials), and scheduling (which jobs run in what sequence to meet demand within capacity). Most SMEs have informal demand input and no capacity model, which is why they're always either overpromising or underutilising.

Build a capacity model first. For each production line or work centre, what is the maximum output per shift, assuming current manning and no downtime? What is the realistic output after accounting for planned maintenance, shift changes, and average downtime? The gap between maximum and realistic capacity is your planning buffer.

Create a weekly production schedule. Every Monday, plan the week: which orders run on which lines, in what sequence, with what material requirements. Share it with procurement (so materials are ready), sales (so delivery commitments are based on reality), and the production team (so everyone knows the plan). Review it daily — a plan that isn't reviewed is just a wish list.

Sequence jobs to minimise changeover time. Grouping similar jobs reduces the time lost to setting up for each new run. If your changeover between colour families takes 45 minutes, sequencing light-to-dark rather than random can save hours per week.

Use a simple tool to start. A well-maintained Google Sheet or whiteboard works better than an ERP you don't use. Build the process discipline first; automate later.
