A major headache for most of the companies even today is that of absenteeism. Manual records aren’t completely reliable. Cases of missing data, false data and improper entry usually hinders the processes in HR. Even though technology has been introduced, human intervention is usually necessary to keep the data credible. Thus, bringing us back to ground zero. How does one keep accurate account of absenteeism?
Similar was the case of our friend Gopal, A HR executive in a XYZ company. He was tasked with the responsibility of processing monthly attendance of the employees. As a part of the process, he downloaded attendance punch times record from the attendance server. All the fields were critical. So, what was Gopal going to do now?
In such a case, he decided to bring in Six Sigma expert Prof. SK into the scenario. The breakdown suggested that there were five fields to enter data referring to attendance records. Prof. SK calmly assessed the case and made notes in his notebook. The notes were as follows -
- The Number of opportunities to go wrong for a form = 5.
- Six Sigma measure to be applied.
- From 1000 records completed during the month, we must draw a random sample of 100 forms and inspect for defects. (i.e. take a small sample size for inspection)
Post thorough inspection of 100 forms, 4 defects were found in 2 records. Gopal reckoned that their team had done a good job by achieving 98% quality (as 2 in 100 are defective records). Payroll department requirement was minimum of 97%.
Prof. SK’s Performance measurement on Six Sigma scale:
4 defects were found from 500 (100*5 opportunities).
This implied that the DPMO* was 8000.
Performance on Six Sigma scale was 2.41σ on a scale of 1 to 6σ.
Performance was considered below industry average, but satisfactory considering internal customer requirements.
Though the process exceeded internal customer (payroll) target of 97%, Gopal and team need to improve quality %, and continue to track and monitor performance on Six Sigma scale.
Prof. SK served as a timely aid to Gopal in helping him processing attendance is an immaculate manner by using Six Sigma measures.
*(DPMO or Defects per Million Opportunities) is one of Six Sigma measures. It is calculated by using the following formula,
DPMO = (defects/total number of opportunities) * 1,000,000
