How EAs Build and Manage a Rolling 90-Day Plan

An EA (executive assistant) can use a 90-day plan to keep an executive’s top priorities on track all year long, well beyond the first three months on a new job.

A rolling 90-day plan works differently from a one-time onboarding plan. Every month, the EA checks off finished work, updates what is still in progress, and adds new priorities to keep the plan 90 days ahead at all times.

This article shows exactly how that works. It covers what goes into a rolling plan, how an EA builds one with the executive, and how to keep it accurate month after month.

TL;DR: How Can an EA Create and Manage a Rolling 90-Day Plan for an Executive?

An EA runs the plan on a fixed monthly cycle, built around goals the executive sets:

• The executive names 3 to 5 goals for the quarter in a short meeting with the EA.
• Each goal is split into smaller steps due on day 30, day 60, and day 90.
• The EA checks the plan weekly and updates it monthly.
• Finished steps get closed out, unfinished ones get a new date, and a fresh month is added to the end.
• Each step gets time blocked on the calendar, so the work actually happens.
• The executive approves the goals, and the EA keeps the plan up to date.

What Is a Rolling 90-Day Plan for an Executive?

A rolling 90-day plan is a short list of an executive’s most important priorities for the next 90 days. The EA updates it every month instead of replacing it at the end of each quarter.

The word “rolling” describes what happens during that monthly update. The EA marks finished work as complete, adjusts anything still in progress, then adds one fresh month of priorities to the end of the list. The executive always has a full 90 days of planned work in front of them.

The EA is the natural owner of this plan. Day-to-day executive assistant tasks and responsibilities like calendar management and follow-ups show which priorities are moving and which have stalled.

Contacts in other departments fill in the rest before each monthly review. u/PumpkinExpert455 described building those relationships in a thread on succeeding as a new EA:

“A lot of the first year is mastering a good communication stream, workflow, and building trust – not just with the CEO but with everyone in the org. The more you talk with/meet people and engage with them, the more trust you earn on an organizational level, which helps build your/the CEO’s ‘brand’. The ‘BEST’ EAs, in my opinion, are proactive, not reactive.“

A rolling 90-day plan puts that groundwork to use every month.

How a Rolling Plan Differs From a 30-60-90 Onboarding Plan

Both documents use the same three numbers, though the similarity ends there.

A 30-60-90 onboarding plan belongs to a new EA. It sets out what they will learn in month one, what they will take over in month two, and what they will run on their own by month three. Once the EA is up to speed, the plan has done its job and gets filed away.

A rolling 90-day plan is about the executive rather than the EA. It tracks the goals the executive is working toward in the current quarter. The EA keeps adding to it every month. Nobody ever finishes it.

The table below sets out where the two differ:

ProAssisting co-founder Ethan Bull wrote about the 3-month onboarding plan on LinkedIn:

“Every time someone asks about a ’30-60-90-day EA onboarding plan,’ I can’t help but laugh a little. Here’s why: EA onboarding isn’t some mechanical process that begins in month one and ends in month three. It begins in the first 30 minutes of the first meeting and is like a dimmer switch… gradually increasing in brightness. A good partnership with an EA should start paying dividends almost immediately.” 

Ethan’s point is that useful support does not wait for a three-month window to close. A rolling plan works the same way. 

How an EA Builds a Rolling 90-Day Plan

An EA builds the plan at the start of each quarter, following the same three steps every time:

Mapping the Executive’s Quarterly Priorities

The first step happens in a conversation. The EA sits down with the executive for 30 to 45 minutes at the start of the quarter. The executive shares their priorities with their EA for the next 90 days.

For example, a CEO names three goals for the quarter:

• Close the funding round.
• Hire a VP of Sales.
• Ship the new product feature.

Those three goals become the plan. The EA keeps the list to 5 goals at most, because a longer list pulls the executive’s attention away from the work that matters.

u/GrungeCheap56119 warned incoming EAs against trying to work them out alone, in a discussion about building a plan as an incoming EA:

“Work on observing. Have 1:1s with your manager and ask open-ended questions to get them to set goals and expectations. Don’t try and pretend to read minds. A lot of people go this route; it doesn’t work. Ask. Observe everything.“

Skipping the conversation creates problems later in the quarter. u/doloresphase started a role without having it and found out months in about work nobody had mentioned:

“One thing I would recommend is sitting down with your boss and discussing what initiatives need to be hit by the end of the year and how you can help execute them… I didn’t realize until 3 months in that no one was planning the holiday party… and it got thrown onto me because the marketing girl was terminated before I joined. I also didn’t realize I had to prepare decks for different quarterly meetings they have. These are things that you probably won’t be explicitly told to do until it’s too late.“

Recurring commitments belong on the list too. Board meetings, investor updates, and quarterly reporting all take up real time on the executive’s calendar.

Breaking Priorities Into 30-60-90 Horizons

Next (once the priorities are set), the EA breaks each goal into smaller steps spread across the quarter.

Here is how that looks for the above example on the CEO’s funding round:

• Day 30: The pitch deck and financial model are finished.
• Day 60: First-round meetings with investors are done.
• Day 90: The term sheet is signed.

The EA writes down the following things about each step:

• Priority: The goal in the executive’s own words, such as “close the funding round.”
• Milestone: The step due at day 30, 60, or 90. Examples include “pitch deck finished,” “10 investor meetings booked,” and “term sheet signed.”
• Owner: The name of the one person who has to deliver that step. Writing “the finance team” instead of a name leaves nobody accountable when the date arrives.
• Target date: The exact calendar date the step is due, such as March 14. Listing a whole month leaves room to procrastinate.
• Dependency: Anything that has to finish first before this step can start. For example, the pitch deck cannot be completed until the CFO signs off on the financial model.
• EA actions: What the assistant does to move the step forward, such as booking investor calls or preparing briefing notes.

Setting the Review and Roll-Forward Cadence

The EA reviews the plan on three schedules once it is built:

• Weekly check, 15 to 30 minutes: The EA looks at the coming week alongside what is due later in the quarter. If day 60 is 3 weeks away and no investor meetings are booked yet, the EA raises it now.
• Monthly update, 30 to 60 minutes: The EA closes out finished steps, updates dates for steps still in progress, and adds a fresh month of work to the end of the plan.
• Quarterly reset, 60 to 90 minutes: The executive picks new goals for the next 90 days. The EA then rebuilds the plan around them.

The monthly update keeps the plan moving forward. Without it, the plan turns back into a document nobody touches.

Every step gets one of two outcomes at that meeting. The EA either marks it done or moves it forward with a new date.

EAs already do this with daily task lists. u/jonesy18yoa explained how to run through the previous day’s list with an executive who never says what he finished, in a thread on tracking an executive’s to-do list:

“As you get ready to assemble tomorrow’s list, read off today’s. His choices are cross off or carry over. Then you do the list for tomorrow.“

The monthly review works the same way, one month at a time instead of one day.

Writing the results down each time keeps the record accurate. u/312midwestgirl says in the same thread:

“For 4 years, I sent my exec/CEO a daily EOD (end of day recap). It consisted of tasks that I completed, pending items (both short- and long-term so we didn’t lose sight of things), and ‘looking forward to tomorrow’ at the end, aka her schedule the next day. I would keep it in a running Word document that I would email EOD before I left the office. I can’t even tell you how many emails back and forth it saved us both.“

Running a plan this way asks a lot from a regular assistant. Someone booking meetings and clearing an inbox does different work than someone tracking a funding round across 90 days.

ProAssisting is a premium executive assistant service built around that second kind of support. Every ProAssistant has at least 5 years of experience as an executive assistant or project manager at globally recognized brands, like Walmart and many more. Quarterly planning is familiar ground for them.

Executives who want to walk through their own quarter can book a 30-minute call with ProAssisting to get started.

Example of an Executive Rolling 90-Day Plan

A working example makes the structure easier to picture than any description.

The example plan below belongs to a CMO starting the second quarter of the year, working with an EA who keeps it updated.

At the day 30 review, the EA closes out everything in the first column. Say the sitemap is approved, but the page copy is still with legal. The copy moves into the day 31 to 60 column with a new date attached.

The EA then adds a fresh column of day 90 milestones on the right. For this CMO, that might mean reporting website traffic against the old site, planning the summer campaign, and setting 30-day goals for the new content marketer.

The plan now runs to the end of July instead of the end of June. Repeating that step every month keeps a full 90 days of work in view.

How to Set Up a 90-Day Planning Rhythm with the EA

Setting up the rhythm takes one meeting plus a few decisions about where the plan lives and who updates it.

Here is how to set it up:

1. Set the goals before the quarter begins: The executive and EA should meet in the last week of the current quarter. That way the plan is ready on day one, rather than the first two weeks passing with nothing agreed. 
2. Share the source documents with the EA: Board decks, the annual plan, and department updates all contain goals related to the plan. An EA who only sees the calendar will miss most of them.
3. Keep the plan in one shared file: A Google Doc, a Notion page, or a project board all work. What matters is that both people open the same file, so the weekly check never starts with a debate about which version is current.
4. Block calendar time for each milestone: When a milestone goes on the plan, the working hours it needs should go straight into the calendar. For example, if the pitch deck takes 6 hours to write, book 6 hours for it that month. 
5. Fix the weekly review to the same slot: Fifteen minutes every Monday morning works better than an hour that keeps moving. A fixed slot means the review actually happens each week.
6. Let the EA handle the updates: Marking milestones done, chasing colleagues for a status, and preparing the monthly review all sit with the EA. Keeping that work off the executive’s plate is the whole point.

Step 4 matters most, because unplanned meetings take up so much of the week. Microsoft’s Work Trend Index found that 57% of meetings are ad hoc calls with no invite behind them.

Half of all meetings also fall between 9 and 11 am or 1 and 3 pm, which is when most people do their sharpest thinking.

Blocking focus time is already common practice among EAs. In a thread on managing an executive’s calendar, u/DisneyBounder explained how to pair it with weekly planning:

“My solution, personally, would be to block out an hour or so in the morning and an hour or so towards the end of the day for no meetings… Then maybe set up a catch-up between you both for calendaring where you can both sit down and plan the following week and put in any extra focus time they need on an ad-hoc basis.“

How an EA runs a time-blocked calendar explains how to set those blocks up.

Frequently Asked Questions (FAQs)

Below are a few questions that come up regularly around rolling 90-day plans:

Why 90 Days Instead of a Full Year?

Ninety days is long enough to finish meaningful work and short enough that the plan still reflects reality. 

Annual plans lock in priorities that have often changed by spring. A quarterly cycle forces that decision 4 times a year, so the plan keeps pace with the business.

Who Approves the Priorities in a Rolling 90-Day Plan?

The executive approves them. The EA suggests what should go on the list, updates the plan, and tracks progress, but the final call sits with the executive.

The executive’s main priorities can be very different from what an EA thinks they are.

Can a Part-Time or Fractional EA Manage a Rolling 90-Day Plan?

A fractional executive assistant can manage a rolling plan without difficulty, since the workload pattern suits part-time support well.

The work comes in bursts. There is one longer session each quarter, a monthly update, and a quick check each week. The rest is chasing people for a status, which fits around other work.

How Is a Rolling 90-Day Plan Different From an OKR or Quarterly Goal?

An OKR sets a target and measures the result against it. A rolling 90-day plan covers the schedule instead, deciding what gets done in which month and how much calendar time it needs.

For example, if the OKR is to grow trial signups by 40%, the rolling plan puts “landing page live” in month one and books the CEO’s time to review the copy.

Conclusion

A rolling 90-day plan keeps an executive working on the right things all year. They pick 3 to 5 goals each quarter. The EA breaks each one into steps due at day 30, day 60, and day 90, then updates the plan at the end of every month.

Handling that sort of precision needs an assistant who can hold the whole quarter in view. They also have to know when a slipping deadline is worth raising. Finding someone at that level is the hard part.

ProAssisting solves that. ProAssistants have supported executives and board members at Walmart, Sony, Airbnb, Fidelity, Oracle, and JP Morgan Chase. Experience of that caliber normally costs a lot to bring in-house.

ProAssisting delivers it for 50 to 80% less than a full-time hire with its fractional model.

One conversation is enough to see which parts of your workload a ProAssistant could take over. Executives can share their current workload and get matched with a ProAssistant by booking a call right now.
