“The first fortnight is a convention, not a published standard. Five moves the Government Digital Service, the Design Council's Double Diamond and Ideo's phases all imply: access, evidence, framing, a decision map and a go or no-go.
The first fortnight removes ambiguity
The first two weeks of a project decide whether the next two months are about the work or about arguments.
The Government Digital Service states the principle without hedging: understand the problem before committing to build, and let what you learn decide whether to build at all.
Two weeks is a convention, not a standard
This article makes a claim in its title that the sources do not support: no primary publication fixes a duration for discovery. The Government Digital Service prescribes no number of days. It prescribes an order — understand the problem before you commit to building — and states that you should not start building your service in discovery.
Read the fortnight as a working convention, then. It is short enough to force decisions and long enough to gather evidence, and what actually matters is the sequence of moves, not the calendar. A studio that runs the same moves over three weeks is doing the work. One that presents ideas in week one and calls it discovery is doing something else, and you will pay for it in month three.
Five moves that belong in the fortnight
-
01
Access
The studio gets into the rooms, the systems and the records: support tickets, sales calls, the questions the front desk answers all day. The client grants; the studio asks in a list.
-
02
Evidence
Interviews, a service walkthrough and an audit of the surfaces that already carry the name. The rule from the service manual holds: understand the problem before committing to build.
-
03
Framing
The Design Council’s Define phase produces the brief that frames the fundamental design challenge. It is written after immersion, which is why it belongs at the end of the fortnight and not in the kickoff invitation.
-
04
Decision map
A named approver, a substitute, and response times nobody has to guess. The Design Council asks for a clear brief for sign off by all stakeholders; the names behind that sentence are the map.
-
05
Go or no-go
What was learned decides whether the project continues, which is the purpose the service manual gives the phase. A written yes and a written no are both outcomes.
Evidence in the first fortnight, and theatre
What shows up when the fortnight is real
- A dated problem statement with the sources behind it
- Access to real users and the complaint log
- A decision owner, a substitute and agreed response times
- A definition of done the client has signed
- A first delivery proposed after the evidence, not before it
What shows up when it is theatre
- A strategy deck inside week one
- A mood board assembled before anyone met a user
- Visual routes presented while the problem is still assumed
- A workshop with notes on the wall and nothing in writing
- A calendar whose first visible output is the creative presentation
The Double Diamond, read for the order
The Design Council describes the Double Diamond as a simple way to describe the steps taken in any design and innovation project, and it is precise about the job of the first diamond: understanding, rather than simply assuming, what the problem is. That sentence is the whole reason this article puts framing at the end of the fortnight.
Ideo’s Design Kit sequences the same discipline in three phases: Inspiration, where you learn from the people you design for; Ideation, where you make sense of what you found and prototype; Implementation, where the work reaches the market. Two frameworks, different vocabulary, one order. Neither of them sets the strategy in the kickoff workshop, and any studio that does should be asked which model it is following.
What the client owes in the same fortnight
Access, with a date on it
Introductions to the desk staff, the complaint log, the analytics account and one customer call the studio can sit in on. Access given in week three is access given too late, because the framing document will already be written. Treat it as a deliverable with a due date, not a favour granted when someone has time.
One approver, plus a substitute
A studio cannot map a decision it is not allowed to see. Name the person who signs, the person who signs in their absence, and how long a review may sit unanswered. Pentagram’s own copy claims that the owners of the business act as the primary contact for every client — company copy worth testing — while on your side the equivalent promise is a name written down before the first review, not an organisational chart.
What success is measured on
Agree the measure in week two, or the project will be judged in month six against whatever is convenient that week. A measure does not have to be financial: time to answer a customer, the number of conflicting versions of a document in circulation, or the share of enquiries that reach the right team. Write it down with the person who will collect the data.
A definition of done, signed
The Design Council’s Define phase asks for a clear brief for sign off by all stakeholders because an unsigned brief is a rumour. Set out what ships, in which languages, on which surfaces, and what the studio hands over at the end — masters, rules and the working files. The structure of that document is covered in how to write a creative brief an agency can use.
The moment that justifies the fortnight
The purpose of discovery is not a document; it is a decision. The service manual ties the phase to a go or no-go on building at all, which means the fortnight should close with a written answer in either direction. That is a cheap sentence to write and an expensive one to skip.
A no-go is not a failed project, it is the cheapest possible outcome: the problem was understood before anyone committed three months to it. A studio that will not present that option has a commercial reason, and the buyer should know what it is.
Three claims about discovery that do not hold
Discovery has a fixed duration
No primary publication fixes two weeks or six weeks for discovery. The service manual prescribes no duration at all; it prescribes that the problem is understood before building starts. Anyone quoting a standard number is describing a scheduling habit, and habits are negotiable.
Strategy is set in the kickoff workshop
Both reference frameworks put framing after immersion: the Design Council’s first diamond is Discover, before Define, and Ideo’s Inspiration phase precedes Ideation. A strategy agreed in the first meeting is a hypothesis in a confident voice, and it usually survives because nobody tested it.
Elite studios publish a standard discovery product
Mostly they do not. Collins lists service programs such as brand refresh and repositioning, without a documented discovery process on its about page, and it is not alone. Ask what your engagement will produce instead of assuming a common template, and judge the answer against the structure in how to choose a design agency.
The rule in the service manual’s own words
Before you commit to building a service, you need to understand the problem that needs to be solved.
Craft, and buildings, and the cost of being late
In a partner-led studio the owner is in the room
Structure decides who attends week two. In a partner-led studio the person who sells the work is also the person who makes it: Pentagram claims that the owners of the business are the creators of the work and serve as the primary contact for every client, which is company copy rather than an audited fact. Test it by looking at who is actually in the room.
Where that structure does not exist, ask for its equivalent in writing: the named person who will run the fortnight, the days they are attached to your project, and the person who attends the go or no-go conversation. Discovery is the cheapest place to find out whether the seniority you paid for has been allocated or only promised.
What to do with this on Monday
- Write the five moves into the engagement before week one.Access, evidence, framing, a decision map and a go or no-go are the deliverable of the fortnight.
- Put a written decision at the end of it.What the manual says you learn in discovery should decide whether you move on at all.
- Name one approver and one substitute in week one.An unsigned brief is a rumour, and an unmapped decision is a delay waiting for month two.
- Ask for framing only after immersion.The Design Council’s first diamond comes before Define; Ideo’s Inspiration comes before Ideation.
- Check who actually attends week two.Pentagram’s owner-as-primary-contact line is company copy, so verify it in the calendar rather than the deck.
- Refuse any quoted standard duration for discovery.No primary publication fixes one; the order of the moves is the standard.
