Product backlog
Also known as: backlog, product roadmap items, backlog prioritisation
Definition
A product backlog is a priority-ordered list of everything that could be built into a product: it is not a dated plan, it is continuously revised, and one person, the product owner, is accountable for the order of it.
The operative word is ordered. A backlog where half the items are marked high priority has no priorities at all: the order has to be linear, from what gets built next down to what waits. Items differ in how far they are worked out: the top of the list is described in detail, estimated and ready to start, while the bottom may exist as a single line. The regular refinement session exists precisely to bring the top of the list to a state the team can pick up without further questions.
Prioritisation should not rest on the conviction of whoever argues loudest, so explicit frameworks help. MoSCoW splits items into must, should, could and not this time, which is simple and works well for a fixed scope. RICE scores reach, impact, confidence and effort and produces comparable numbers, which helps when several departments are arguing. Any framework beats intuition for one reason: it makes the basis of the decision visible, so three months later you can revisit it without reconstructing the context from memory.
Three backlog pathologies show up more than the rest. The dumping ground: a thousand items accumulated over years that nobody searches any more, because filing a new one is easier. No owner: priority is set by whoever wrote in the chat last, and the team switches direction weekly. And a backlog with no technical items, where refactoring, dependency updates and debt repayment never enter the list and therefore never happen, until the system starts falling apart and demands attention anyway, in emergency mode.

- Technical debtTechnical debt is the accumulated gap between how a system is built and how it should have been built: every shortcut taken to hit a deadline turns into a permanent surcharge on the cost and duration of everything built afterwards.
- MVPAn MVP is the first release of a product that carries exactly one user journey end to end, shipped in four to eight weeks so the demand hypothesis gets tested against real users and real payments rather than survey answers.
- Technical specificationA technical specification is the document that fixes what exactly will be built and on what grounds the work counts as accepted: goals, roles, scenarios, screen-level requirements, integrations, non-functional requirements and an explicit out-of-scope section.
- Fixed price vs time and materialsFixed price and time and materials are two contract models: the first fixes scope, deadline and price with the risk premium sitting on the contractor, while the second pays for hours actually worked at an agreed rate and leaves scope control with the client.
- DiscoveryDiscovery is a one to three week pre-project phase that frames the problem, studies users and competitors, describes scenarios and constraints, and produces a prototype, a specification and an estimate with a justified range instead of a number pulled from the air.

- IT consulting and product auditThe most expensive mistakes in software happen before the first line of code: a misread problem, a stack chosen out of a contractor’s habit, and a specification that does not exist. Consulting exists to settle all of that before the development meter starts running: what to build, out of what, at what cost and in which order. The result is a document, not an opinion on a call.
- Web app and Telegram Mini App developmentFor when a site is no longer enough and you need a product: an account area, a dashboard, an internal tool or a Mini App inside Telegram. We design the architecture, write the backend and frontend, and take it to release.
- Website support and improvementNot every project needs a rewrite. It is often cheaper to fix the speed, clear the technical SEO errors, add the missing sections and integrations, and end up with a working site without paying for a new build.
