Fixed Budget. Continuous Delivery.
Senior Full-Stack Node.js React.js Developer, 6 years SaaS experience. No estimates. Weekly delivery. Predictable budget.
Why this approach? Because 66% of IT projects fail,
with 32% failing due to unrealistic estimates
(
My solution: Fixed monthly budget. No estimates. Continuous delivery.
The Bottom Line
You get predictable costs, continuous value delivery, and the ability to adapt daily to what actually matters for your business.Why 66% of Development Projects Fail
Let's be honest. You know it's all theater:
Planning Poker
Developers "estimating" features they've never coded, with mystical Fibonacci points. 3-hour meeting to decide if it's a 5 or an 8. Result? It was actually a 21.
The Gantt Chart
That beautiful colorful schedule saying you'll have your app in 6 months. 9 months later, you're at 60% and the budget has doubled.
The "Sprints"
2 weeks to do X, Y and Z. Except on day 3, you discover the priority is W. But no, we continue with X because "it's in the sprint". It's like taking 100 steps with your eyes closed only to discover you're facing a wall - 99 steps too late.
Estimation "Ceremonies": Closer to Spiritualism than Science
Think about it for a second. We call them estimation "ceremonies". Not "analyses" or "calculations". CEREMONIES. As if we're invoking spirits to predict the future.
And what do we actually do?
- We ask developers to guess with "mystical points"
- We use the Fibonacci sequence (why not tarot cards?)
- We play "poker" like in a casino
Developing software means creating something that has never existed. So how can you estimate the time needed to invent the non-existent?
"Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own."
- Matthew 6:34
In software development, we should focus on today's priority. Not plan weeks ahead before even solving today's problems.
"Suppose one of you wants to build a tower. Won't you first sit down and estimate the cost to see if you have enough money to complete it?"
- Luke 14:28
That's exactly what I propose: a fixed monthly budget. You KNOW how much it costs. You control the duration. But the content adapts to reality.

How I Guarantee Your Budget (Without Fantasy Estimates)
- Frédéric Leguédois, USI 2025(external conference)"Planning is just a heap of information that's useless today and will be wrong tomorrow."
Instead of wasting weeks estimating the unestimable, what do we do?
Imagine a fruit basket vendor. You pay €50 per week for your basket. You don't know exactly which fruits you'll get - it depends on the season, the market, what's best. But you know that:
- The basket will be full and overflowing
- The fruits will be quality
- The vendor will adapt to your tastes
- If you're not happy, you stop the subscription
That's exactly how we should sell software development.
"Be patient, then, brothers and sisters, until the Lord's coming. See how the farmer waits for the land to yield its valuable crop..."
- James 5:7
A farmer doesn't know exactly when their harvest will come, but they work every day. Similarly, we don't know how long complete development will take, but we deliver value every week.
Fixed budget like your weekly basket
Focus on Real Priorities
Every day: We review priorities based on what we've learned. No 2-week sprints. Just common sense and responsiveness.
100% Predictable Budget
€12,000/month. You control the duration, not me. No bad surprises, no budget overruns.
Continuous Visible Results
As soon as a feature is ready, it goes to production. Sometimes several times a day. Permanent adaptation.
"Instead of bronze I will bring you gold, and iron in place of wood, and bronze in place of stones; instead of stones, iron."
- Isaiah 60:17
We don't wait for the perfect "gold" version. We first deliver the working "wood", then progressively improve.

I decided to stop the theater:
- ❌ No more estimation "ceremonies" worthy of spiritualism
- ❌ No more schedules that will be wrong in 2 weeks
- ❌ No more "Flash-stimate" which is still quick divination
- ❌ No more illusion that we can predict development's future
My philosophy aligned with experts:
"The prudent give thought to their steps."
- Proverbs 14:15
In software development, that's exactly it: being attentive to each step we take. Not waiting until we've taken 100 steps to discover we're facing a wall - that's 99 steps too late.
"Go to the ant, you sluggard; consider its ways and be wise! It has no commander, no overseer or ruler..."
- Proverbs 6:6-7
No need for managers or complex schedules when we keep things simple and know what we have to do.
Daily Adaptation
We keep a long-term vision (where we want to go), but we adapt daily (how we get there).
Continuous Feedback
Daily feedback means watching where we step at every moment.
Deliver > Plan
Focus on value delivery, not on predictions.
Direct Communication
No imposed format, just what's necessary to move forward.
"The purposes of a person's heart are deep waters, but one who has insight draws them out."
- Proverbs 20:5
Real communication requires listening and presence, not forms.

What Experts Say
"Estimates are waste. Not only are they not necessary, but they introduce dysfunction into the team."
- Allen Holub, #NoEstimates(external article)
"I may have invented story points, and if I did, I'm sorry now."
- Ron Jeffries, story points creator(external article)
"We stopped using and promoting Planning Poker in 2003."
- James Grenning, Planning Poker inventor(external post)
Beware of False Solutions
Even Vasco Duarte's method with his "#NoEstimates" is still based on "Flash-stimate" (estimating if a story takes between 0.5 and 2 days). Sure, you discover earlier that the schedule won't be respected. But then what? You redo the schedule. Which will be postponed. Then postponed again.
The fundamental problem remains: we plan work in advance without knowing if it will be the priority on D-day. It's just postponing the problem, not solving it.
Approach Based on Proven Practices
My approach relies on:
— Deliver value continuously
— 12 simple principles, not complex framework:
"Our highest priority is to satisfy the customer through early and continuous delivery of valuable software"
"Welcome changing requirements, even late in development"
"Deliver working software frequently, from a couple of weeks to a couple of months"
— Timeless principles that apply perfectly to modern development
"The plans of the diligent lead to profit as surely as haste leads to poverty."
- Proverbs 21:5
Being diligent without being hasty: having a clear vision (roadmap, OKRs) but adapting daily.

Frequently Asked Questions about Developer Subscription
"But how to plan without estimates?"
Excellent question! We don't plan the impossible. We define a budget (€12,000/month) and maximize value within that framework. It's like our fruit basket: fixed budget, content that adapts to what's best at the moment.
"What if I have a critical deadline?"
Perfect! Without estimates, we focus 100% on what MUST be ready for that date. No "nice to have" features. Pure business value. That's exactly where the approach shines.
"Isn't it just day-to-day development?"
It's value-oriented development with daily feedback. Like the prudent person who gives thought to their steps, we check every day that we're going in the right direction. We don't wait 3 months to discover we messed up.
"What about average-based forecasting methods?"
Even "modern" approaches remain problematic. Take Vasco Duarte and his "#NoEstimates" - it's really "Flash-stimate" (0.5 to 2 days per story). OK, you discover earlier that the schedule is slipping. And then? You redo the schedule. Which will be postponed. Again and again.
The real problem: why plan work without knowing if it will be the priority on D-day? As the Agile Manifesto(external site) says: we value responding to change over following a plan.
"Why do companies cling to estimates?"
Frédéric Leguédois explains it well: it's their "organizational security blanket". This illusion of visibility and predictability that reassures. It's cultural. Companies want to believe they can control everything, predict everything.
If developers must "commit" to 2 weeks so the company can plan, it's useless. No good company will force its developers to deliver the impossible. So we'll redo the schedule. So why do it in the first place? Isn't it waste and betrayal to customers who need us to build, not plan?
