In Production and deskwork alike,workflow is associated with sequences. You can improve operation efficiency by segmenting the sequences and grasping the flow in each segment.The segments are called processes. Manufacturing consists of production processes in which the raw materials turn in to products through many steps of processing and assembly. Process analysis means to plan individual process, observe the status quo, conduct investigation, and decide the philosophy of improvement.
The following describe the flour principles of improvement (ECRS),which represent how you look at things in order to present ideas for improvement of the tasks in the workplace impartially. The following is an outline and does not deal with specific process analysis procedures that require expertise.
In many operation improvement activities, ECRS is often the first item to focus on.
(1) Eliminate: Can the task be eliminated?
Is it really necessary? Asking that question helps you find wasteful tasks that can be eliminated. Before moving to steps (2) to (4) , you need to examine the process closely. the most familiar example would be the 5S. In principle,the first thing to do the 1S, clearing up, to immediately eliminate what is unnecessary. Yet people tend to fail to get rid of things, forcing themselves to keep worrying about the 5S every day. The basic way is to look for tasks that are difficult to do (Strain), and consider if they can be eliminated.
2. Combine: How about combining the tasks ?
If tasks cannot be eliminated, reorganize them in the simplest way possible. if you look carefully, you can find many ways that you can improve efficiency shortening the walking path of reducing handwork, for instance.
3.Rearrange: Can the tasks be rearranged in a different order?
There are cases where you can improve things by swapping people,machines,tools, and materials or replacing them with others. For instance, you can replace a right-handed operator with a left-handed operator if the task requires work by the left hand.
4.Simplify: Can the tasks be made easy or simple?
Excessive packaging may be a familiar example that can be addressed by this approach. Changing the order of tasks or the positions of things often saves time and labor.
