striving for high performance \u2013 be it for your business or a personal competency, you should be interested in tracking metrics that indicate if changes need to be made to improve.\u00a0\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Managing a software engineering team might involve measuring the lines of code written or perhaps the number of&nbsp;<a href=\"https:\/\/www.mountaingoatsoftware.com\/blog\/what-are-story-points\">story points<\/a>&nbsp;the team has accrued over the course of a&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Scrum_sprint\">sprint<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In learning a language with the Duolingo app, the primary measure of progress is the number of points I have earned between Monday and Sunday.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Insurance companies measure the number of new customers gained.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Airlines gather metrics showing the number of unoccupied seats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Behaviour adapted for metrics<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">People or businesses will inevitably amend their behaviour if there is a particular metric (or metrics) that define their success \u2013 they are likely to optimise so that their metric scores are as high as possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For instance, if I worked in an organisation that only measures and rewards me for my promptness in replying to emails, I am likely to optimise the way I work so that responding to emails becomes my top priority.&nbsp;&nbsp;The downside is that it is likely that I am going to be distracted in meetings, the thoughtfulness of my emails will most likely suffer and the time I spend in&nbsp;<a href=\"https:\/\/www.calnewport.com\/books\/deep-work\/\">deep work<\/a>&nbsp;will be restricted to those times when my colleagues of clients aren\u2019t sending email.&nbsp;&nbsp;Focusing our attention on a particular set of metrics is inevitably going to cause side effects.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A&nbsp;<strong>software<\/strong>&nbsp;engineering team is likely to lower their focus on the performance, quality and elegance of their code if they are being measured purely on the number of lines written.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Duolingo\u2019s<\/strong>&nbsp;weekly finish line is Sunday, which is also when time runs short, so I frequently rack up quick, easy points on Duolingo by repeating the beginner lessons I have already mastered \u2013 and in doing so, I will learn nothing new.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>An&nbsp;<strong>insurance<\/strong>&nbsp;business focusing on bringing in new business may end up doing so at the expense of loyal customers, who become disgruntled at the superior prices offered to new customers.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Airlines<\/strong>&nbsp;overbook flights to ensure seat utilisation is as near to 100% as possible; but in the pursuit of flights departing at full capacity, the airline may be forced to turn passengers with paid-for tickets away \u2013 and be faced with having to pay them compensation .<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Pair the yin metric with the yang metric<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/en.wikipedia.org\/wiki\/Andrew_Grove\">Andy Gove<\/a>&nbsp;suggested that when identifying a measure, a counter-measure should be paired with it.&nbsp;&nbsp;The counter-measure represents the unwanted side effect that introducing the measure could inadvertently foster.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>In software<\/strong>, the number of lines of code written should be paired with a quality metric and a performance metric<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>The Duolingo app<\/strong>&nbsp;should measure (and score me) based on new material I have learned over a given week as well as scoring me by the number of lessons taken&nbsp;<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Insurance companies<\/strong>&nbsp;should pair the metric of new customers with the retention of existing ones<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Airlines<\/strong>&nbsp;should not just measure the number of seats occupied, but also the number of passengers turned away due to the flights being overbooked<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Metrics in business and in life are like the displays in a cockpit \u2013 the improvement in one positive measure (rate of ascent) needs to be assessed in tandem with a counter-measure (airspeed) \u2013 if this isn\u2019t done,&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Stall_(fluid_dynamics)\">stalling<\/a> becomes a risk in aviation and in life in general.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Picking the right measures needs to be balanced and holistic in order to drive meaningful and sustainable positive outcomes.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you are striving for high
