In my last post I argued the case for choosing jobs that play to your strengths, rather than trying to build up expertise in areas of weakness. Perhaps I was too sweeping. On reflection, context is critical and you need to correctly diagnose the situation you face – another lesson from Good Strategy, Bad Strategy.
I still see limited value working on weaker skills if they don’t matter match for the job you do, or the one you want to do in future. Even if they sit on your organisation’s ‘competency framework’. But weaknesses, including gaps in experience, do need addressing when they significantly hold back your ability to get – and do – the job you want in future.
When your performance in a particular job is determined by your proficiency and experience across multiple different competencies, it exhibits what Rumelt calls ‘chain link’ logic. At its most extreme this means overall performance is constrained by the strength of the weakest link. This link becomes a bottleneck holding up performance. An example in a career development context could be that you won’t be considered for a senior management position until you’ve completed some relevant training, or more frustratingly obtained some management experience (a classic chicken-and-egg problem).
More likely though, the different competencies could be highly complementary, so that there is value in building up proficiency and experience in all of them. Focusing on weaknesses will be particularly valuable when there are diminishing returns to investment in each competency – so that 1 day spent working on a strength pays back less than a day working on a weakness.
I don’t think chain link logic always applies though. Some skills and experiences just aren’t that useful for your ability to do a particular role. And often people can do the same job in different ways – and equally well – by applying different skills at different levels of intensity.
I found it quite useful to think through the logic from a running perspective, as an analogy to career development. It might help to illustrate these points.
As an marathon runner, it surely makes no sense for me to ‘broaden my experience’ by racing the 100m or investing in sprint training. Better to work on endurance and compete longer races.
However, that is only looking at situation from a very high level. Zooming in, a marathon runner gets better by doing more than just running long. Threshold runs, core stability and mental toughness are all important. If you have a major weakness in any of them it can seriously limit performance and it makes sense to focus energy on these, rather than just the training you enjoy and do well.
Extending the analogy, if I wanted to try my hand at triathlon, it would be foolish for me to invest much time in running training, when I have the potential for much greater gains from improving my fairly lamentable swimming technique.
What this brings home to me is that it’s vital to do a decent diagnosis of the situation. What skills and competencies do you actually need for the job you do, or the job you want to do? Which of them matter most? Where could you increase your level of proficiency most easily?
