The 10x striver: A short story, about you.
Chapter 1 - Planning
You're a programmer, you're in the middle of sprint planning with your team. A new feature has been requested by a customer and you've been given the go-ahead. The feature seems pretty simple: add a nice popup to tell the user they're being a silly bugger putting a string in the age picker. You think of the app, you know there are places popups have been used, you've not seen the code, but you know its there.
You take a momentary glance at the other developers who are watching expectantly, waiting for the question. "So, how long do you think this will take you?". This is your moment, this is your time to shine, nothing can stop you, you're a 10x. You let out a loud sigh to ensure you have everyone's undivided attention. "Half a day".
Chapter 2 - Half a day
Half a day, half a day, half a day. This is now your mantra.
It has been a week since you uttered those words. Every morning you have had to drag yourself to your morning stand up and repeat, "I'm still working on...". You make up excuses about the code in the area being hard to understand, unreadable or an insufficient amount of tests. You wish you could rewind time and give a more reasonable estimation.
It is not YOUR fault
So many of us have been there, we've completely underestimated a task we thought was trivial and it took far longer than we could ever have expected. This is not your fault, this is something humans are inherently bad at.
It is fortune-telling.
This is commonly known as the planning fallacy which is a phenomenon where predictions on how much time a particular task will take to complete are exceedingly optimistic, often disregarding the knowledge of prior, similar tasks.
The planning fallacy only occurs when planning for our own tasks, interestingly, us humans take a much more pessimistic approach when estimating for other people.
And also, the more knowledge you have around a certain area the smaller that optimism bias gets. So that explains why the senior developer who has been working on the app since the beginning was shaking his head at you when you said half a day.
We want to impress
Everyone wants to be decent at what they do, everyone wants to be an asset to the team. You want to be the developer who can get sh*t done.
And in our want to impress we only increase the amount we underestimate tasks (As shown by the brilliant story aboveπ€£). Unfortunately, as programmers, a lot of our sprint-planning meetings are done in groups so that need to impress is often multiplied.
Pressure from above
Often it is not just the need to impress which can skew our estimations, it could also come from your team leader, or your project manager, or the CEO of the bloody company.
We all love Elon Musk, but blimey does he make some crazy deadlines. I can only imagine the pressure the engineers must feel working for him!
It's not all bad (Parkinson's Law)
Parkinson's law is the notion that work expands so as to fill the time available for its completion. So basically, you know that time when you had to finish a school assignment in 2 days and you managed to get your shit together and get it done? That's Parkinson's Law.
You underestimating the time it's going to take you to implement a feature may make you work harder at hitting the deadline, but that's only if you place a high degree of importance on getting it done. If you aren't all that bothered if your work takes longer than estimated then Parkinsons Law probably won't have much of an effect.
This is likely why Elon Musk makes crazy deadlines for his engineers, putting them in a perpetual state of Parkinsons Law forcing them to work their asses off.
So how do I get better at estimating?
In Software Estimation by Steve McConnell he recommends:
- Breaking the problem into sub-problems or sub-tasks
- Estimate using ranges rather than giving an explicit date (This depends on how your company estimates)
- Find similar completed tasks, so how long it took you to implement a feature in the same area. Essentially use your prior knowledge.
- Understand your margins - if you're estimating something completely new you might need to take a 100% or even 400% factor.
- Communicate with the appropriate people about your estimation as you refine it.
Finally
I wrote this blog because as I said, humans are inherently bad at estimating, but I myself am probably even worse than the average human. Even just this week I've underestimated a ticket I thought would take me a couple hours, probably prompting me to write this blog.
The moral of the story:
if you're shit at estimating, don't worry about it, we all are.
I'd love to hear your thoughts and or stories of times you've underestimated a task or even your own tips for making estimations. Equally, I'd like to hear from the 10x developers who estimate bang on every time π.

We also estimate the happy-path, solving if everything goes smooth. When was the last time you said "this should take 5 minutes" and there you are 2 hours later, installing drivers and reading arcane config syntax..
Yeah thatβs so true, Iβll be honest, it happens far too often in my case π
Let's break it down a bit. The process looks like this:
The first sign of barrier should make us stop and think. When we branch out to 3 Chrome tabs, following how to configure various deps. Or get a result from a call that is not expected according to the docs.
I'm not saying we should throw up the white flag, but we have to ask ourself: This seems rather 4 hours instead the 10 minutes I hoped. Is it worth the investment, or should I stop now?
You are right, totally right with your article. I'm currently in a position where I have to estimate a lot of projects/solutions and estimating the time is something that makes me crazy. Overall because I could be the person in charge of that project and it's completely possible that I forgot some tasks or constraints.
In my company, we only estimate the effort for coding/configuring phase and then complete the rest of the phases (analysis, design, testing, ...) as a percentage of it. For example, I estimate implementing an API could be 5 days of coding, the testing phase will be 80% of it so we will spend 4 days. The whole task will be the sum of all these phases getting a final time of 9 days for this case.
In addition to this, we set a lot of assumptions to avoid forgetting anything. Think of a web application you estimated creating a simple user interface but that doesn't mean anything to your customer. You need to add some assumptions for limiting the scope like: no CSS rules will be developed. This is something the customer will understand or, at the end of the day, you will have as a shield to defend your position.
Thank you for this, I love hearing how people take different approaches to estimate tasks. Your approach is very interesting, we do a relatively similar thing at work although we have Quality Assurance engineers who estimate the effort for testing and that gets bundled on top of the overall estimate.
Thanks for this. QA team is a good thing to test the whole product but there are a lot of tests in a project lifecycle. You have to include some effort for unit testing, integration tests, smoke test, user acceptance tests, etc. So, there should be something in the estimation to cover testing saying what kind of test are included in the estimation so you can adjust the percentage of the effort of the team.
Do your estimations include the time QA team will spend in the project? This is something you should consider to include inside or outside your estimation and you should co-work with your QA mate.
We take this approach too, but also add another batch of time for iterations. How many times does the mock-up not do justice to the task or a fringe case wasn't caught in the original API design? Those things we take into account for as well when we estimate.
I learned that estimations are a value we said based on experience, calculus or any other technique we used. So, if a customer requires an API implementation for their business logic, we will estimate the implementation of a number of services and their complexity, let's say 5 services with medium complexity, and not the final solution - a description of what each of these 5 services will do like a black and white box. In the assumptions section (or any other place), we will define what means "medium complexity" so fringe cases will be considered out of the scope of the current project and we should include a note telling need an assessment to give a proper estimation for that issue, problem, requirement or system.
We, as estimators (that exists?), need to limit what we are estimating and considering. We cannot give the final solution in the estimation so we are not able to include fringe cases if we don't study them.
I liked
Making Things Happen(akaThe Art of Project Management), which despite the title, is a totally BS-free book about overseeing a project. Has great advice about estimation. You can pop it open anywhere your current interests are.In my case, it's because I'm a perfectionist most of the time, and refuse to do ad-hoc solutions. That being said, I tend to always under-estimate the time needed to finish the project.
On the other hand, when I'm laser focused and free of distractions, I seem to be able to summon a huge amount of coding mantra, and produce more quality code that I ever expected to be possible. To paraphrase the last sentence; I sometimes still manage to surprise myself, even after 20 years of coding.
I love that feeling, somedays you feel like you could just take any ticket and code it up in a few minutes, embracing that inner 10x.
Me too!!!
Same here! Trance, deep house, lowkey tech... ππ΅
When it comes to frontend nowadays I feel like I am really good at estimate tasks. We estimate a task and it's risk separately. For example this might be a half a day task but it has a big risk (two days). So it's fine if that task spans for 2.5 days. Also modern frameworks like angular made predictions even easier due to their structured nature
Yeah, I agree with this, to be honest, a lot of my dodgy estimations are because of the unknown of the backend, but sometimes the frontend does catch me out!
Alternative:
...
The project is actually delivered in 4 months.
Spot on!
Moral of the story.
Great SELLER!!!
Back when I was a wee CS student a professor I respect a great deal told us to estimate the time and then just double it. At the time I think a lot of us only half-listened to all these "old guys". Now that I'm approaching old guy status I accept most of what they said. π€£
That said, there's a reason why many companies/projects don't have precise, external roadmaps as to what's coming when. It's easier for things to slip than predict a hard date. Better to delay than "ship" something not ready.
I'm convinced it's more witchcraft than science, really.
Haha the older you get the more you realise that these old buggers actually made some sense π
At a previous job, we used to estimate time and log time on our sprint tasks. I am very guilty of underestimating tasks from optimism, pressure, and trying to impress. Eventually I got better by just adding a padding of time from my actual estimates, but if I went over that then I would feel super poopy.
These days where I am uses points and so far it's been far less stressful being constraint to an approximate amount of work than being constraint to a time to be done.
Not that points is the answer but it's been better for me!
I've used a point system also but we end up converting the points into days anyway. Like 1 point would be half a day, 2 points is a day, 3 points is 2 days, etc. I don't know whether that's just company-specific, but I like the idea of using points without the conversion to time!
A lot of it I'd imagine is company-specific. We don't do straight time conversions because points have to account for initial work, work post PR to address comments, and QA.
It's been an adjustment but it's been pretty good so far.
Are you trying to describe me??
I need to improve on this as well. I once estimated a 5 month project could be completed in 1, maybe 2 months tops. Yeah, that didn't work out very well.
Since then I have tried to be more pessimistic when estimating.
I have not got much better at it, but I haven't got worse as least ππ
π that's brilliant, I've never had to estimate an entire project but I can only imagine that's 10x worse, so, so many unknowns!
This week I was given the task of solving a bug on the application front-end. It looked simple enough so I said when I asked that you should be solving by tomorrow (Monday). Well, I still have no idea how I'm going to solve it. It is basically some bug around Samsung smartphones' keyboard predictive text that makes the user input act like crazy. I tried a lot of things already, but it seems Samsung was very crafty as to how to turn developer's life like hell. u.u
Not always. I've known a number of cases where bosses, clients, or even co-workers set unrealistic deadlines for others. (You even mentioned a few such cases.)
By the way, I've written about this phenomenon as well, and broken it down into several root causes and how to fix them.

Yeah of course, as I mentioned with Elon Musk setting unrealistic deadlines!
What I meant is that if someone from a 3rd party standpoint were to make an honest estimation of time for a particular person to do a task it would likely be more pessimistic.
