PRD vs BRD vs SRS: Which Requirements Document Do You Need?
A BRD (business requirements document) explains why a project exists and what the business needs from it. A PRD (product requirements document) describes what the product does for its users. An SRS (software requirements specification) states, precisely enough to build and test against, how the system must behave. Most small projects need the content of all three but not three separate files.
Open Questions and Assumptions Log: Keep Unknowns Visible
An open-questions log lists what you do not know yet, with a named owner and a due date for each item. An assumptions list records what the plan treats as true without proof, and which part of the estimate depends on it. Keep both from the first discovery call, review them every week, and close or carry forward every item before sign-off. Most scope arguments later in a project start with an unknown that nobody wrote down.
How to Estimate a Software Project: Give a Range
To estimate a software project, split the work into milestones, give each one a low, a likely and a high figure in person-weeks, write down the assumptions those figures rest on, and add a contingency with a stated rule for using it. The client gets a range they can budget against and a list of what would move it. This article walks through each step with an example table you can copy. Why one number misleads A single figure such as "26 weeks" sounds precise, but it hides how much is still unknown.
Software Project Roadmap Template: Milestones and Estimates
A software project roadmap at the end of discovery is a table of milestones, each with a start date, a target date, an effort range, the milestone it depends on and the requirements it delivers, plus a short list of the assumptions behind it. It answers "what gets built in what order, and roughly how long will it take". Below is the table to copy, how to find the critical path, and a filled-in example with a month-scale timeline.
Client Documents in AI Tools: A Checklist for Agencies
You can put client documents into an AI tool, but only after you know where the text goes, how long it is kept, whether it trains a model, who else processes it, and what your contract with the client allows. Those five answers differ a lot between a personal chat account and a business product built on a commercial API. The checklist below works for any vendor, and the last section shows how Discovery Phase AI answers it. This is a practical checklist, not legal advice.
Stakeholder Analysis for Software Projects: A Template
A stakeholder analysis for a software project is a short table of the people who can shape, block, use or pay for the product, with what each of them needs and how much say they have. You build it in the first days of discovery, use it to plan interviews and sign-off, and keep it up to date until handover. This article gives you the columns, a power and interest grid, and an invented example you can copy.
Discovery Phase AI vs ChatGPT: an honest comparison
ChatGPT is a good tool for drafting parts of a discovery phase: a problem statement, a first list of requirements, a summary of a call. Where it struggles is keeping a whole discovery together, with ten connected stages, changes over several weeks and one document at the end. A purpose-built tool such as Discovery Phase AI is worth it when that second job is what costs you time. If it is not, a chat assistant and a good template will do.
Discovery phase in software development: steps, deliverables, cost
A discovery phase is the short stage at the start of a software project, before design and development, in which the client and the delivery team agree what problem they are solving, for whom, what the product must do and whether it can be built within the budget. It usually takes two to eight weeks. It ends with a written set of deliverables (goals, requirements, architecture, wireframes, a roadmap with ranged estimates and a risk list) and a decision: build, build something smaller, or stop.
How much does a software discovery phase cost? A person-weeks model
A software discovery phase usually costs somewhere between a few thousand dollars and several tens of thousands, and large regulated projects go well beyond that. The honest answer is a calculation, not a number: people on the team x weeks x blended weekly rate. This post shows what agencies publish, why the figures disagree, and how to build a range you can defend, whether you are buying a discovery or pricing one.
