Integrity is not free

What would you do if you feel that you have a fantastic opportunity, but following it would mean a betrayal of your values, and not following it would hurt your career? Questions like this repeat themselves in multiple stories since the dawn of ages. In them, the protagonist resists the urge and stays true to themselves, which leads to a happy end.

In reality, humans often act differently – this is why this trope is so often used. A significant number of couples cheat, entrepreneurs lie to their customers, leaders break their promises, and employees play dirty games.

Playing dirty is easy, and it feels damn good to trick the world („I deserve this” and other forms of self-deception to justify this is another topic), but such a decision comes with a guaranteed cost. The cost is your integrity.

While it isn’t valued by many, integrity is a crucial factor which differentiates true leaders. Staying true to yourself gives an emotional strength, clarity in decision-making, and makes other people trust you. We are social creatures. This is why people hate hypocrisy in others, as it means that this person can’t be trusted. You will not follow such person, as it is much riskier than you will be betrayed.

In most cases, your unethically achieved benefits will fade, or to keep your new status they will require additional shady decisions. Sunk cost fallacy can lead such person to an awful place in life. Of course, it might not happen, and it can turn up great. However, the damage which you do to yourself will stay with you and your memories forever.

If you are a person between such decision remember to check with yourself if it is worth it. Ensure that you will be able to live happily with seeing your face in the mirror, after selling out your values.

Pragmatic approach to start estimating in Story Points

Every wannabe agile organisation tries a different approach to estimating using Story Points, which is the standard way to measure work in Scrum. It is hard to start, and after few sprints, teams tend to go back to estimate in hours, even as estimating in Story Points gives more value for the team in the long run. Additionally, this „Story Points” are confusing for external or internal stakeholders, as non-agile people usually estimate effort through hours.

So the first step for confused developers, managers and customers should be linking Story Points and hours in some way, so this measurement is valuable for Scrum team and comfortable for all sides. To achieve that I tend to explain that Story Points are a series of ranges of the probabilities of delivering task in a given amount of time (see the table). It seems to work, so I decided to write it down. You can use it for teams that start working in Scrum, but it might be beneficial for every organisation which earns money by selling hours of developers work.

Humans & estimating

Humans sucks at estimations using abstract values, example: how much grams does this apple weight?

We are much better in comparisons between objects or events, example: is this apple is bigger or smaller than orange?

More obvious the differences the easier is us to decide which option is closer to the „truth”, example: are oranges looks more like mandarines or an apple?

This is why values like Story Points, with big differences between each levels are better tool for estimating than hours.

Exponential complexity

The less you know, the (much) bigger is unknown of possible fuckups.

Complexity of task, and time needed to finish it, tend to it grows exponentially not linearly.

We need to perceive SP and effort like a category on their own.

Values of estimations

This is why Fibonacci-like sequence are so popular as, they aren’t linear which helps our brains to treat it diffrently.

The smaller scope of the task, less SP, the smaller effort variation between other tasks estimated in the same value will be.

I found SP values of 1, 2, 3, 5, 8, 13, 21 – as the most useful for every day work in weekly or bi-weekly Scrum sprints.

Real life anchors

No issue which take less than 15 minutes to do should be need to be written.

Even simplest tasks worth writing, tend to take around one hour. This is my lowest anchor, and I give this type of tasks 1 SP.

The biggest issue which should be in the sprint scope should be possible to finish in one week sprint. This means it should take around 40h. So for this type of tasks I set 13 SP.

For bi-week sprint the time we have is 80h, so I set this to be 21 SP type of task

Tips & tricks for the future

It will never be a perfect way to predict the future.

Avoid 13 & 21. Try splitting them, as the smaller issue is the lower uncertainty you will have.

With time this time ranges will evolve, and this is healthy! Feel free to adjust them after your team knows themselves better.

Developers should be challenged and accounted for their estimations. Let them learn on their mistakes – this is the most crucial part for creating self-improving teams.

Be careful into creating more detailed estimation ranges, as they make the whole process longer, and more stressful for developers while providing just illusion of better control for management.

As a manager, deciding where between „Linear” and „Exponential” hours on average tasks will be is your way to take into account project risks.

If you are clueless, assume that team will be around „Exponential” value, as planning fallacy makes us underestimate approximately 60% of total time needed for finishing complex task.

The way the human brain works

An ignorant mind is precisely not a spotless, empty vessel, but one that’s filled with the clutter of irrelevant or misleading life experiences, theories, facts, intuitions, strategies, algorithms, heuristics, metaphors, and hunches that regrettably have the look and feel of useful and accurate knowledge. This clutter is an unfortunate by-product of one of our greatest strengths as a species. We are unbridled pattern recognizers and profligate theorizers. Often, our theories are good enough to get us through the day, or at least to an age when we can procreate. But our genius for creative storytelling, combined with our inability to detect our own ignorance, can sometimes lead to situations that are embarrassing, unfortunate, or downright dangerous – especially in a technologically advanced, complex democratic society that occasionally invests mistaken popular beliefs with immense destructive power (See: crisis, financial; war, Iraq).
