One of the added absorbing aspects of scrum is the adeptness to accredit credibility to stories. The botheration is, award abundant advantageous admonition about this abstraction is absolutely challenging. First, what are adventure points? Next, how do you finer accredit credibility aback they assume rather arbitrary? I appetite to try to admonition you accomplish faculty of this. In the end, what we appear up with ability not be an official analogue and explanation, but it’ll absolutely admonition you bigger accept how to use this affection in your team’s scrum system.

In simplest terms, a adventure point is a amount absorbed to an accomplishment for commutual a task. It’s like advantageous accomplishment with a grade, abandoned instead of A-F, it’s maybe 1-5. You completed a arduous task, you get a 5. Complete a simple task, you get a 1.
But what do these credibility mean? I see two means to attending at adventure points. The aboriginal way is affectionate of the official take, which makes it accessible to appraisal excess in agreement of accomplishment (instead of hours). Abounding teams acquisition this beneath daunting. On top of which, it’s appreciably easier to accredit a akin of adversity to a assignment than it is to accredit the cardinal of hours a assignment will take. And this is at the affection of scrum. Why? Because change happens.
You ability anticipate you apperceive absolutely how continued it will booty to accomplishment Assignment A, but things change and hurdles are consistently befuddled in your way. You ability accept been assigned 20 hours to complete assignment A, but in reality, it ability booty 30 or 40. On the added hand, you are bigger able to apperceive how difficult Assignment A will be to complete.
In the end, a aggregation can attending at several tasks they’ve been assigned and see that the absolute accomplishment circuitous will be, say, 40. If there are abandoned eight tasks involved, they can be assured that claiming awaits them and they’d bigger accept their A-game at the ready.
It’s confusing. But remember, this isn’t aloof about complexity, but about effort. For example, the README file. These aren’t decidedly circuitous but can absorb a lot of autograph and collaboration. That ability booty ample effort. So, alike admitting the README isn’t complex, it’s time-consuming, so it ability be assigned 5 adventure points.
But let’s accede addition acumen to use adventure credibility … a acumen you won’t acquisition them accounting about often.
Competition.
Let’s face it, developers are aloof as aggressive as added advisers (maybe added so). Developers like to blow about their accomplishments (and accurately so; developing is be a absolute arduous profession).
Although adventure credibility were never advised as a admeasurement of success, they can absolutely be acclimated as such. At the end of a sprint, how abounding adventure credibility has anniversary aggregation collected? You see area I’m activity with this.
The aggregation with the best adventure credibility could absolutely be rewarded. After all, a bit of antagonism is a abundant incentive. Alike if there aren’t absolute rewards, the aloof rights abandoned are account implementing adventure points.
Of course, this isn’t the accustomed (or accepted) use of adventure points, but let’s face it … it’s valid.
This is area it gets a bit cloudy. Truth be told, it’s all appealing arbitrary. How abounding credibility is a assignment worth? Do you know? Is there an official arrangement of measurement? There is not.
Say you accept Assignment A which is almost easy, such as breeding an antecedent commit. On a calibration of 1-5 (1 actuality easiest, and 5 actuality best difficult), that assignment is apparently a 1. Every developer should be able to do an antecedent accomplish in their sleep. And what about that README we talked about earlier? It could be as simple as artful and pasting from a boilerplate (story point 1), or it could crave a acceptable accord of aboriginal content, some analysis and accord (story point 3).
Of course, there’s no acumen adventure credibility accept to be bound to 1-5. Depending on how abundant assignment you appetite to put into it, you could accept adventure credibility from 1 to 50. Here’s what I advance you do. First, actualize baselines for anniversary adventure point. Let’s go aback to the README file. Let’s stick with the simplistic 1-5 scale. Say all of your READMEs are appealing simple, acute not abundant added than licensing information, acquaintance information, and a description of the project. That’s a 1.

Next is autograph code. Maybe one programming assignment abandoned requires a developer to bung in a few functions from a library. That’s a 2 because it’s appealing cut and dry. But what if you accept a assignment that’s all aboriginal code, but not so circuitous that it’ll actively claiming a developer. You accept yourself a 3.
What about a allotment of cipher that’s a aggregate of aboriginal and some pre-built cipher from libraries and frameworks? Give that a 4. Finally, you accept a level-5 adventure point assigned to the best arduous tasks that ability crave autograph new functions.
Then, of course, there’s architecture (maybe 3), testing (possibly 5, because testing can booty ample effort) and deploying (probably a 2 or 3).
Granted, I’m aloof about allotment numbers to these tasks, but you get the idea.
Another accustomed adjustment of allotment adventure credibility is application a Fibonacci sequence. So, instead of numbers incrementing by one, they acceleration according to the Fibonacci arrangement (the sum of the antecedent two numbers), as in 0, 1, 1, 2, 3, 5, 8, 13, 21, etc. With such a sequence, you could added calmly accredit adventure credibility to tasks. For example:
What’s important about the allotment of adventure credibility is that you be consistent. If these credibility assume random, they won’t absolutely be fair. To that end, advance a baseline so you not abandoned abstain approximate numbers, but it can become abundant easier to accredit adventure points.
And there you accept it … my booty on scrum adventure points. Your business apparently has a absolutely altered booty on how this affection works, but it’s consistently acceptable to accede added ideas. Regardless of how you use and accredit adventure points, aloof accomplish abiding you are consistent.
