You will want to analyze the work content so you can eliminate the NVA work, thus reducing the overall process time. Processing time will consist of CVA, BVA, and NVA work. Timing the duration of each work activity will give you insight into possible bottlenecks, excessive work content, and how long it will take to deliver product or service to your customer.

It’s important to know how long your process time is for an activity as well as the nature of the work being done. Why is process time important to understand? Knowing your process time will allow you to do this analysis. That way, you would have a balanced system with no idle time, or in-process WIP. In a perfect world, you would have all your process steps working at the same processing speed. Steps of long duration might end up being bottlenecks, which will delay subsequent steps from moving the item through the process. Identify potential opportunitiesīy analyzing the processing time of each process step, you should be able to identify where some process improvements might be.

The addition of all the processing times plus the waiting times will give you the approximate overall process lead time. Since your time to process at each step drives your overall process lead time, there will be benefits to that overall process lead time if you improve your individual processing times. Any slower, and you might build up WIP between your process steps. Any faster and you won’t meet your customer demand. If you do, you may be building up WIP, or work-in-process, which can actually slow the process down.Ī traditional Lean metric known as takt time provides information as to the maximum process time allowed to meet your customer demand.

In any case, you will rarely want a single process time to be as fast as it can be, especially if the process is a series of sequential steps. Then you can assess whether the CVA and BVA can be improved. That would reduce the processing time for that step. The first thing you might do is evaluate the work being done and eliminate any NVA. Both you and your customers should aim to minimize that processing time so you can increase your throughput and capacity while delivering your product or service more quickly to the customer. That time might be customer value-added (CVA), business value-added (BVA), or non-value-added (NVA). Process time is the actual time a person spends working on a specific item or task. Waiting is usually considered non-value-added work and should be reduced or eliminated as much as is feasible. That total time consists of the processing time at each workstation plus any waiting or queue time while in the process. The time it takes from when an item enters a process until it exits a process is called process lead time (PLT), or Little’s Law.

In this article we will define process time, the benefits of reducing it and a few recommendations on how to improve the time someone spends on a specific process task. The time to complete a process step is what process time is all about. Your customer must wait for their product or service until all the processing has been completed.
