When an agency relationship is not delivering, the default analysis focuses on the agency. The team is not senior enough. The strategic thinking is shallow. The creative work is safe. The account management is reactive. These complaints are sometimes valid. More often, they are a description of what happens to even good agencies when the client side of the relationship is not working. Agencies perform to the quality of the brief they receive, the decision-making speed they encounter, the feedback they are given, and the clarity they have about what success looks like. Poor performance on any of these dimensions produces poor agency output, regardless of the agency's underlying capability.
Good agency management is a client-side discipline. It is learnable, and the absence of it is the most consistent cause of agency relationships that cost more than they deliver. Most marketing teams have never been taught it, most agencies are too commercially cautious to demand it, and the result is an industry full of relationships where neither party is getting what they need.
What agencies need to perform well
Agencies need four things from clients to produce their best work: a specific brief with a clear success criterion, a decision-making process that is fast enough to allow creative momentum, feedback that is directional rather than prescriptive, and a relationship in which they feel genuinely invited to push back on briefs that they believe are pointing in the wrong direction. Most client organisations provide none of these things consistently, and wonder why the work is consistently below the capability demonstrated in the pitch.
Brief quality is a client responsibility
The quality of the brief is entirely the client's responsibility, and it is the single most controllable variable in the quality of the output. Agencies will often help clients improve briefs — a good account team will ask questions, push back on vague objectives, and request missing information. But the fundamental job of defining what the communication needs to achieve, who it needs to reach, and what success looks like belongs to the client. Agencies that write briefs on behalf of passive clients almost always produce work that the client later describes as "missing the mark" — because the agency wrote a brief that the client should have written, and the inevitable gap between what the client wanted and what the brief said produced work that satisfied the brief but not the client.
An agency performs to the quality of the client. Give them a vague brief, slow decisions, and prescriptive feedback — and you will get mediocre work from even the best team in the market.
The feedback loop that makes or breaks agency output
The most damaging pattern in agency-client relationships is prescriptive feedback: clients who respond to creative work by describing what they want changed rather than why the work is or is not meeting its objective. "Make the headline shorter" is prescriptive feedback. "The headline is not landing the benefit we need to communicate — it is describing the feature but not the outcome for the customer" is directional feedback. The second version gives the creative team something they can solve. The first version gives them a task that may or may not produce a better headline, because the client does not know whether the problem is the length or the content.
Training the team to give feedback against the brief rather than against personal preference is one of the highest-leverage improvements any client organisation can make to its agency relationships. It is also one of the most culturally difficult changes to sustain, because feedback against personal preference is a deeply ingrained habit that is comfortable for the giver and demoralising for the recipient.
The governance structure that agencies actually need
Every agency relationship needs a clear governance structure: who on the client side is the single decision-maker for creative sign-off, what is the agreed turnaround time for feedback at each stage, and how are disagreements about creative direction escalated? Without this structure, agency work gets reviewed by multiple stakeholders who have not been coordinated, feedback is contradictory, and the agency spends more time managing internal client politics than producing good work. Establishing the structure at the start of the engagement — and holding it when internal stakeholders want to bypass it — is the client-side work that determines whether the agency is able to do its job.
When to review the relationship versus the work
The discipline of distinguishing between a relationship problem and a work problem saves significant time and money. If the brief quality is good, the feedback is directional, the governance is clear, and the agency is still not producing work that meets the objective — that is a relationship problem. It may be that the agency does not have the capability the client needs, or that the team assigned to the account is not the team that pitched, or that the relationship has run its course and a different agency would serve the brief better.
But most "relationship problems" are actually work problems caused by client-side failures that are easier to blame on the agency than to fix internally. Before you change the agency, audit the client: is the briefing process producing briefs the agency could win with? Is the feedback process giving the team what they need to improve the work? Is the decision-making fast enough to allow the creative process to work as it should? Answer those questions honestly before you decide the problem is the agency.
