Manufacturers are always looking for ways to increase capacity. When the shop gets busy, adding another machine, hiring more people or adding a shift can seem like the logical next step.
But adding capacity is expensive. Before spending the money, take a closer look at how you're using the capacity you already have.
Small production interruptions add up. Material isn't ready. A machine sits between jobs. Employees wait for information. Priorities change and the schedule gets shuffled around. Jobs spend too much time sitting between operations.
These problems are common in manufacturing, but that doesn't mean you have to live with them.
ERP software can help find where you're losing time and give you the information to do something about it.
You can't improve capacity if you don't know where your time is going.
Start with the basics. Compare estimated hours to actual hours. Look at setup and run times. Check workcenter loads. Review material shortages and schedule changes. See which jobs move through the shop efficiently and which ones always seem to get stuck.
ERP puts this information in one system so you can see what's really happening on the shop floor. The key is looking for patterns.
If one operation regularly takes longer than estimated, your routing may need work. If a workcenter constantly waits for material, you may have an inventory or purchasing problem. If jobs are always getting pushed around, your schedule may not reflect your true capacity.
The problem isn't always where you think it is. Good ERP data helps you find it.
Buying another machine doesn't help much if the real problem is material shortages, bad scheduling or inaccurate production data.
ERP helps connect the pieces that keep production moving.
Accurate inventory helps get the right material to the right job. Scheduling based on real capacity gives employees a better idea of what to work on now and next. Shop Floor Data Collection shows what's happening with jobs in real time. Accurate routings give you better information for scheduling, costing and future estimates.
When those pieces work together, you spend less time reacting to problems and more time getting parts through the shop. That recovered time is capacity.
A machine being available for eight hours doesn't automatically give you eight productive hours.
True capacity depends on your people, machines, material and workload. It also depends on having accurate information about how long jobs actually take.
ERP gives you that information. With accurate production data, you can schedule jobs based on what your shop can actually handle instead of what you think it can handle. You can see overloaded workcenters earlier, reroute jobs when necessary and understand how changing priorities will affect the rest of the schedule.
It also makes decisions about new equipment easier. If your machines are loaded, your people are productive, and you're still running out of hours, adding equipment may be the right move. At least you're making that investment based on hard data instead of guesswork.
You don't need to overhaul the entire shop to get more capacity.
Start with the areas where you lose the most time. Fix inaccurate routings. Improve inventory accuracy. Reduce the time jobs spend waiting between operations. Give employees better visibility into what they should work on next.
Then keep going.
A few minutes saved on one job doesn't sound like much. Those minutes add up when the same problem happens every day across multiple jobs, machines and employees. ERP makes those problems easier to see and easier to measure. More importantly, it gives you a way to tell whether the changes you're making are actually working.
More capacity doesn't always mean more machines or more people.
Sometimes it means better scheduling. Better inventory. More accurate production data. Fewer jobs sitting around waiting for the next operation.
That's where ERP earns its keep. Use the data you already have to find bottlenecks, reduce wasted time and move parts through the shop faster. Get as much as you can from the people and equipment you've already paid for.
Then, when it's actually time to add capacity, you'll know it.
