Dear Mobeen,
Workload analysis is not a simple process or even a single day's process unless proper industrial engineering or work study techniques are employed over a period of time to arrive at appropriate time factor for each job/activity of a worker, as a prelude to workload analysis.
These techniques are:
1) Activity Analysis for each activity of all individual workers for several days (a complex job):
2) Creation of a job list (a very simple process);
3) Preparation of job description sheet with each fragmented step of activity for each job type listed in the job list (somewhat complex job);
4) Time test for measurable jobs to be conducted on selected population of workers at various places for time taken by each worker for each individual step of every job segment out of the job description sheet (The most complex part);
5) Work measurement (quantification) of total No. of different jobs entrusted to each workers with time intervals, i.e., daily, weekly, monthly, yearly, or casually;
6) Analytical estimation of time for jobs that cannot be time tested easily and arriving at a workable standard time for such jobs (a tough job);
7) Arriving at the average time taken by each individual time test performer for each step of job and job as a whole separately to arrive at some measurable time factor for each job;
8 ) Working out some sufficient coefficient for the unforeseen items of work and events, like interruptions, distrubances, inward calls, visitors, personal attendance on call by superiors, attending to call of nature, attending to queries from internal audit, statutory audit, tax audit, vigilance inquiries, and so on;
and finally--
9) Application of time factors as arrived at against ites 6, 7, and 8 above.
In other words, the activity of workload analysis initially may need all the aforesaid acts, which may take even more than a year when you would be able to include annual events to arrive at time factor for such items. For example in banking/financial institutions six-monthly or annual interest calculation, checking & verification can be a major event, which cannot be overlooked. Fraud investigations, internal audit, etc. may also take a major chunk of time. However, once the work standards and norms are fixed, there would not be much botheration in making workload analysis on annual basis.
