EVALUATING IMPACT
This is the twelfth posting regarding labor/labour productivity and disruption. This contribution provides thoughts on the evaluation of impact of overtime on labor productivity. The Subject Series can be viewed here.
Overtime or Extended Working Hours represent one of the widely recognized causes of loss in labor/labour efficiency or productivity. A key issue for project planners and managers is the notion of how to evaluate this impact. The evaluation challenge is present whether the analysis is prospective (contemporaneous) or retrospective. Retrospective analyses can be used or required during project execution or part of forensic analyses.
Regarding the evaluation techniques, K Pickavance (please see below for citation) organizes the methods as follows:
- “Planned (undisrupted) versus actual (disrupted)”
- “Actual (undisrupted) versus actual (disrupted) – the measured mile approach”
- “Historic (undisrupted – on other projects) versus actual (disrupted)”
- “Industry productivity norms (undisrupted) versus actual (disrupted)”
- “Time and motion study (undisrupted) versus actual (disrupted).”
As previously posted, project planning is one of the major challenges for program and project management teams. Past posts have discussed many aspects of project planning. The series regarding Project Management Challenges is here. Part 5 of this series is particularly relevant or germane to the discussion regarding the impact of overtime on labor productivity in this post.
The impact of overtime on labor productivity is a relevant and serious consideration in many aspects of program and project management. In the case of impact assessment, the anticipation of a particular analytical methodology is a planning consideration. Said differently, the project planning should consider the data needed and the collection techniques to be used relative to the assessment of overtime impact on productivity.
Again, the impact on the schedule duration must consider the planned and forecasted progress using the proper productivity. As overtime is introduced, progress may well be impacted. The time impact of more work hours per week is mitigated or offset by the lowered productivity. [Read more…]
