Work Sampling of a Manufacturing Operation - FORM needed

Hello All
I am looking for a form that can be used to conduct a Work Sampling of a manufacturing operation. Work sample of 4 employees over an 8 hours shift. How does one generate random numbers/observation times. I hope someone might have a template that I could use. Thank you!!

Might need more information. How many parts total per run, for example.

Ideas, folks?

I put together a Random Time Generator for you in Excel - see attached. It is really easy to use. Then all you do is observe what each of your 4 employees is doing at these times and record that on a sheet. Then you add the number of times each activity occurs and calculate the percent time they spend on each activity. From there you should get an idea of where to spend your time looking for process improvements.

My company offers a program called 'Timer Pro Professional' (google it) that includes a PDA (handheld computer) version of work sampling - again interfacing with Excel. Once on the home page click the "Play Videos" at the top left and from the "Topics" area click on "Sampling Studies" - look at the video called "Advanced Reporting" to get some ideas on how you can summarize the data you collect.

I am required by the terms of use of this forum to let you know that I am associated with the company that markets the Timer Pro product.

Hope this helps

Doug

Thank you very much for your response. I will attempt to use this tool and get back to you. But this appears to be exactly what I needed. Thanks again.

Thank you for your involvement. I am measuring a Machine tool operation in a job shop enviornment. The output is normally 50 parts per job 4 jobs per shift 4 machine tools. Total output would be 800 units.

Hello,
I have collected the data for a manufacturing line with 2 operators working 8hr/day shifts. Can anyone tell me a good way to analyze the data and obtain results??
Thanks in advance......

Is this precision machining, such as CNC, grinding or milling? If so, I would question why you are looking to sample in this manner.

What is the process? What kind of process variation and distribution do you have? It is important to know - we need more info to help.

The product are tubes (steel) and most of the process is automated except the last 2 processes. I want to calculate the amount of time the operators spend on operations and how much time they are idle. I have used the excel template above to generate random times and noted what the operators are doing at those times. Now I want to analyze this data.

The excel sheet posted in this thread is a good idea. In addition to this, you can also do a elemental analysis to identify idle time in each process. A thorough Elemental Analysis ( Video Based) can help you identify NVA activity. Create a line balance chart using elemental analysis and measure times using the sampling.
