Multiple projects are managed simultaneously in a job shop. Most of them are custom and demand varying production requirements and due dates. These types of high-mix operations can make boosting productivity and maintaining lead times difficult but, finding efficiencies is critical to enhancing profitability and maintaining an edge in the highly competitive manufacturing industry.
Productivity on your job shop floor requires a team of personnel who can keep everything on track and on time. To do that, they need efficient processes, equipment and technology to operate at peak performance. Below are five tips to help focus your efforts on maximizing efficiencies that lead to better job shop planning and higher productivity.
1. Evaluate and Optimize Your Workflow
It’s important to have a baseline to improve upon. Evaluate existing output levels so you can measure any improvements. Then, identify pain points in your current workflows.
Are orders getting hung up between the sales process and production, resulting in delayed timelines? Does inventory run dangerously low before someone realizes it? Is erratic scheduling creating unnecessary bottlenecks on the production line?
Consider creating a value stream map of the flow of materials and information as a way to identify delays in your processes and any factors that impact efficiencies. This team exercise gathers representatives from each area of your organization and maps out the process of completing an order — from the beginning until it arrives at the customer’s loading dock. Ideally, someone with experience in creating value stream maps should facilitate this exercise.
2. Get Organized
When employees end up searching for misplaced tools, supplies or files, it adds up to significant downtime. One study suggests that the average employee spends 38 hours per year searching for lost or misplaced materials and files. Other research suggests the number is likely more than 10 times that much! In addition to the tangible costs, consider how morale is affected and the added frustration and stress disorganization can create.
Many manufacturers apply the Lean or 5S methods for reducing waste and creating standardized processes. Both originated in the Japanese manufacturing sector and focus on eliminating obstacles, creating smoother workflows, preventing equipment failures, implementing cleaning and maintenance schedules, and other procedures. Focusing on these areas helps the shop floor and other areas stay organized and are optimized for efficiency.
3. Evaluate Your Equipment
If your equipment requires more time for repairs than it does for production, you may need to consider whether it’s of value to your organization. Evaluate each piece of equipment and track maintenance schedules. Does maintenance need to be adjusted to proactively address recurring issues rather than waiting until a problem occurs?
Consider using available software and technologies to measure output and monitor performance over time. You may discover that a machine isn’t being cleaned as often as it should be or needs frequent lubrication to operate at peak performance. Sensors and meters can also deliver data to help you determine which equipment is generating revenue and which is failing to deliver ROI for your job shop.
4. Reduce Work in Progress
Most job shops have some level of work in progress (WIP), but too much can tie up cash that could be used to generate higher returns elsewhere. It also takes up space on the shop floor and can pose a risk when kept near equipment or traffic areas.
Excess WIP can result from improper production planning, excessive manual labor, errors in the supply chain and other factors. Identifying and addressing why your job shop may have unnecessary WIP can make a significant impact on improving job shop planning and overall efficiencies.
5. Implement an ERP
Have you considered how many of your processes are redundant? You may have multiple departments using different software and systems to keep track of data, inventory, orders, supplies, customer records, vendors, HR and more. With today’s materials, equipment and software becoming increasingly complex, it’s important to align processes across all business units for maximum visibility and productivity.
An enterprise resource planning (ERP) system can help reduce redundancies, provide actionable insights from the data it gathers, improve production planning and reduce the likelihood of errors. It’s a solution that can be customized to address specific needs, help you grow your job shop significantly and create a competitive advantage.
When you identify inefficiencies within your job shop and focus efforts on improving them, you’ll be in a much better position to grow profitably. Insights from an ERP solution help you make better decisions. When your organization is optimized for maximum production, you may even find that you’re able to get into new markets with new products.
