A short project fails fast and you see it. A long one fails slowly. People leave and take what they know with them, Apple and Google change their rules every year, shortcuts from the first release get expensive, and the plan you wrote in month one stops matching the market by month six. None of this shows up in the first demo.
“Building a functioning system at the beginning helps you avoid most challenges in the future,” Maksim Atiutskii, Business Development Officer at Rocketech, said when this article first ran. That still holds. Below are seven challenges a founder or product owner meets on a project that runs a year or more, and what to set up for each before you sign.
| Challenge | When it shows up | What to set up |
|---|---|---|
| 1. Knowledge leaves with people | The first time someone leaves | Written decisions, shared ownership, a handover rule |
| 2. Platforms change their rules | Every year, on dates you don’t choose | A yearly maintenance plan |
| 3. A stack nobody can hire for | When you need to grow the team | A widely used, well-supported stack |
| 4. Early shortcuts get expensive | Month 3 to 12 | A code review before you scale |
| 5. The plan drifts from the market | After the first users arrive | Small releases and a quarterly re-plan |
| 6. The process erodes | When deadlines get tight | Fixed review points that don’t get skipped |
| 7. Spend loses its link to results | Month 6 onward | Budget tracked against delivered work |
On a long project, someone will leave. A developer changes jobs, gets sick or moves to another team. What they knew about why the code works the way it does often leaves with them.
Surveys show how common the problem is. In the Stack Overflow Developer Survey 2026, 60.9% of 12,374 respondents said important context lives in people’s heads, and 56.5% said the information they find is outdated.
What helps:
On Traza, a booking app for tattoo artists, we added a second developer early to protect the launch date. When one developer dropped out mid-project, we covered the cost and gave the work to the other developer. The client’s budget and timeline stayed the same.
An app you launch this year will need work every year just to keep shipping updates. The stores raise their minimums on fixed dates:
Server code ages too. Node.js says a long-term support release typically gets critical bug fixes for a total of 30 months, and that production apps should only use releases still in long-term support. Node.js 20, released in April 2023, is now end-of-life.
Put these updates in the plan every year, with their own time, instead of discovering them when an upload fails.
The stack you pick on day one decides who you can hire in year three. An unusual framework can be a fine technical choice and still leave you with a short list of people who can work on it. Pick a widely used stack with active support, unless the product needs something rarer, and write down why you chose it.
A first version built fast by whoever was available often works well enough to launch. The bill arrives later, when every new feature takes longer than the last because the base wasn’t built to grow.
Look at the code before you scale the team, not after. When Livetag, a live shopping platform, came back to us after another contractor, there was an existing codebase and strict deadlines. We built the team around the stack already in the code and spent the first iteration refactoring on all platforms. New features came in the second. If you inherit code, a code audit costs a fixed $3,500 and takes 5 working days.
A plan written for a year assumes you know what users will want in month ten. You don’t. The fix is to ship small and re-plan often: release a narrow version, learn from what people do with it, and plan the next quarter from that.
Babystep, a platform that connects parents with learning experts, started as an MVP. After the first release we collected feedback and built new iterations of the web platform. About six months in, it was clear the audience wanted a mobile app, and because the same team had run the project from the start, a lot of code was reused. Our developers later joined Babystep’s in-house team for the long term.
Under deadline pressure, teams skip the review, the retrospective or the backlog refinement first, because nothing breaks right away. A few months later nobody knows what was decided or why.
Fixed review points help: a demo every sprint where the product owner accepts or rejects the work, a short retrospective, and one person who sets priorities. Our guide on why proper management matters for startups lists the minimum setup.
In month two you know what you’re paying for. In month ten, the monthly invoice looks the same while the work behind it is harder to see. Track budget against delivered work: what shipped this month, what it cost, and how a change in requirements moved the dates. When this article first ran, our team described using burn-down charts built from story points and tracked time to show clients, as it happened, how a requirements change affects deadlines.
Plan and estimate one release at a time, then check each plan against what shipped.
To get a first range before you commit to a long build, run your idea through our project estimate. It is a planning range, not a fixed quote.
Losing knowledge when people leave, yearly platform rule changes, early shortcuts that slow every later feature, and a plan that drifts away from what users need. Each one is cheaper to plan for than to fix later.
Write down decisions and their reasons, make documentation part of the definition of done, and never let one person be the only one who knows a critical area.
Every year. Since 28 April 2026, Apple requires uploads built with Xcode 26. From 31 August 2026, Google Play requires new apps and updates to target Android 16 (API level 36).
When the backlog will keep changing for months and someone on your side sets priorities, yes. For a small first version with fixed scope, a fixed-price build fits better.
On a long project the biggest risks are losing people and losing knowledge. Before you sign for a year or more, ask how a team documents its work and replaces a developer without stopping delivery. Explore dedicated development team and the Livetag case study.
