What goes wrong in quarterly planning, and how to avoid it

Most organisations do quarterly planning. Most quarterly plans are out of date by week four. The problem is rarely that the team is not trying hard enough. It is that the planning process produces outputs that are too abstract to act on, and too rigid to survive the things that come up mid-quarter.

The most common failure: priorities without owners ¶

A planning session that ends with a list of priorities and no named owners has not actually produced a plan. It has produced a list of intentions. The difference becomes clear around week three, when the first priority starts to slip and no one is sure whose job it is to notice.

Every priority that comes out of a planning session needs a single named owner, a definition of what done looks like, and a date. Not a team, not a department. One person.

Planning for the quarter you want versus the quarter you have ¶

Quarterly plans tend to be built on the assumption that the quarter will be quiet. In practice, most quarters are not quiet. There are unexpected requests, people who are off sick, and decisions that take longer than expected. A plan that uses one hundred percent of available capacity is a plan that will fail.

A more useful approach is to plan for seventy percent of capacity and treat the remaining thirty percent as a buffer. That sounds conservative. In practice, it is what allows the plan to survive contact with reality.

What an outside perspective adds to the planning process ¶

The value of having someone outside the room during planning is not that they know more than the people inside it. It is that they are not carrying the same assumptions. Every team has things it does not question because they have always been done that way. An outside perspective is useful precisely because it does not share those assumptions.

This is what the embedded quarter engagement is designed to do. Fiona joins the planning cycle, asks the questions that feel obvious from outside, and helps the team leave with a plan that is specific enough to act on.

The review that most teams skip ¶

At the end of each quarter, it is worth spending an hour looking at what was on the plan at the start and what actually happened. Not to assign blame, but to understand the gap. Was the plan too ambitious? Were the priorities wrong? Did something come up that should have been anticipated?

That review, done honestly, is what makes the next quarter's planning better. Without it, the same patterns tend to repeat.

If quarterly planning is a recurring frustration, it is worth looking at whether the process itself needs to change before the next cycle starts.
