Only apply effort that helps you to achieve your goalMy temptation when climbing, as with most men, is to 'brute force' with your arms. In this way I often apply excess energy which is lost on the wall, when a touch more finesse to apply the effort in a more focussed manner would achieve the same result using less energy. If we can identify the activities and actions that contribute specifically to achieving our goal and perform only these actions then we will achieve success more quickly and with resources to spare.
Only carry the weight that is needed to help you achieve your goalAlthough not fat, I am bulky when compared to a 12 year old, and this excess weight can be a cause of drag. Similarly if we have bulky processes, excessive documentation to maintain and too much manual testing then this can limit our progress and use up valuable energy.
Do not fear committing yourself with just what you need to progressOne of the real skills in climbing is knowing how much of a purchase on the wall you need in order to perform a move. The mediocre climber such as myself will not trust in his ability to make a move with limited hand/foothold and so will waste energy finding unnecessary reassurance, when the better climber will move when they have just enough purchase to progress. Similarly a the development/test team can learn that it is possible to commit to work and progress without technical specifications, design documents and the like and just start with a one-line story and a plan to discuss it, then this will free us up to embrace agile/lean processes without the false reassurance that those documents provided.
I'm off down the climbing centre again on Thursday, and will hope to practise what I preach. As with all things, it is easy to talk about the best way of doing something, however whether I can apply these principles when I'm halfway up a wall and my legs have just started shaking like Elvis' is another matter ....
