A new practice usually starts well. The team agrees on a way of working, the first few weeks go smoothly, and everyone feels progress. Then attention moves, a busy period arrives, and the practice quietly fades. Leaders then conclude that the team resisted, when often nothing in the system asked the team to keep going.
Sustaining a change is work of its own. A simple plan for days 30, 60, and 90 after a new practice begins keeps it alive until it becomes routine.
Why changes fade
- No one is asking. Without a regular question about the practice, other demands take its place.
- The leader moves on. Teams read a leader's attention as a signal. When it shifts, so does the team's.
- Early friction is not addressed. Small annoyances accumulate and push people back to old habits.
- The practice depends on a person. When that person is absent or busy, it stops.
- New people never learn it. As the team changes, the practice loses its shared understanding.
Before day 30: define what must hold
Pick the two or three practices that matter most, such as a weekly commitments review, a decision log, or a handoff agreement. Write them in a sentence each, with an owner for each practice. Decide how you will tell if each is happening, for example, whether the review took place, and whether the log was updated.
Day 30: check use and remove friction
At the end of the first month, ask three questions:
- Is the practice happening as agreed?
- What is getting in the way?
- What small change would make it easier?
Gather answers from several team members, not only the owner. Fix what you can quickly. If a template is clumsy or a meeting time is wrong, change it now. Early friction repaired shows that leaders are listening and that the practice is meant to serve the team.
Also recognize specific good use. Name the person who flagged an early risk or recorded a decision so that others see what the practice looks like in action.
Day 60: test it under pressure
By the second month, the novelty has worn off and real pressure has returned. Look at how the practice held during the busiest week. Did the team protect it, or was it skipped? If it was skipped, discuss why, and decide whether to adjust the practice or defend it more firmly.
This is also the time for honest correction. If someone is bypassing the agreed approach, raise it privately and directly, using the same standard you apply to everyone. Without consistent response, others will conclude that the practice is optional.
Review the indicators you chose. Are the practices linked to any movement in the business outcome you care about? Be careful about conclusions, since other factors may be at work, and treat the data as a prompt for discussion.
Day 90: embed it
At three months, decide which practices are routine and which still need support. For the routine ones, reduce active leader involvement while keeping a light check, such as a monthly look at the data. For others, extend the support for another cycle or revise the design.
Make the practice independent of any single person. Document it in a short, plain description, assign a backup owner, and include it in onboarding for new team members. Ask someone other than the original owner to run the next session, which tests whether the practice has taken root.
Keep the cadence going
After day 90, keep a rhythm of review, perhaps quarterly: Are the practices still serving the priorities? Has the business changed in ways that call for adjustment? Which new behaviors should be added, and which retired? A practice kept alive by occasional review stays relevant.
What leaders should watch in themselves
The leader's attention is the strongest signal the team receives. Keep the practice on your own calendar, use its outputs in your decisions, and refer to it in conversation. If you stop using the commitments log, the team will too.
JEM's Culture-to-Execution Sprint ends with progress measurements and a 30/60/90-day sustainment plan, reflecting the view that building a practice and sustaining it are separate tasks. For a leader working on how to model these habits personally, one-on-one leadership coaching offers a private place to plan.
