The 30/60/90 Day Plan Every Interim CMO Should Follow

As an interim CMO, the clock is always ticking. You're brought in to make a significant impact in a limited timeframe. The pressure is immense, and the expectations are high. In my 15+ years of experience, working with leading companies like ING, P&G, and WeTransfer, I've refined a 30/60/90 day plan that allows me to hit the ground running and deliver measurable results. This isn't just a theoretical framework; it's a battle-tested methodology that I've applied in various enterprise environments. It's a more intensive approach than what a fractional CMO might undertake, designed for rapid transformation.

The first 90 days are critical for any marketing leader, but for an interim CMO, they are everything. This concept is famously outlined in Michael D. Watkins' book, The First 90 Days, a must-read for any new leader [1]. This period sets the foundation for your entire engagement. It's where you build credibility, gain the trust of the executive team, and create the momentum needed to drive change. A well-structured plan is your roadmap to success, ensuring you focus on the right priorities at the right time.

Days 1-30: The Rapid Diagnostic Phase

The first month is all about deep immersion and rapid learning. My primary goal is to understand the business, the market, and the team as quickly as possible. This isn't a passive listening tour; it's an active investigation. I'm looking for the 'why' behind the 'what'.

My first step is always to conduct a series of in-depth stakeholder interviews. I sit down with the CEO, the CFO, the head of sales, and other key executives to understand their perspectives on the business, the challenges they face, and their expectations for marketing. This is crucial for aligning my efforts with the broader company objectives. When I joined a major financial institution, for example, my initial conversations with the board revealed a critical disconnect between the marketing team's activities and the company's revenue goals. This insight shaped my entire approach for the following months.

Next, I turn my attention to the marketing team itself. I conduct one-on-one meetings with each team member to assess their skills, morale, and understanding of the marketing strategy. This helps me identify any skills gaps and understand the team's capacity for execution. I also perform a comprehensive audit of the existing marketing channels, campaigns, and budget. I dive deep into the data, looking for what's working, what's not, and where the biggest opportunities lie. A thorough review of the MarTech stack is also essential to understand the tools at our disposal. This includes assessing the potential for introducing agentic marketing and AI agents to automate and enhance our capabilities.

By the end of the first 30 days, I have a clear picture of the current state of marketing and have identified a handful of quick wins. These are high-impact, low-effort initiatives that can deliver immediate results and build momentum. This could be as simple as optimizing a key landing page or refining the targeting of a major ad campaign. These early successes are vital for building trust and demonstrating value. For instance, at a major e-commerce player, we identified that a simple tweak in the checkout process could reduce cart abandonment by 15%. This was a quick win that had an immediate impact on the bottom line and earned me the trust of the executive team.

Days 31-60: Building the Marketing Engine

With a solid understanding of the business and some quick wins under my belt, I shift my focus to building a robust marketing engine. This is where I start to implement more significant changes and lay the groundwork for long-term success. The goal of this phase is to move from a reactive to a proactive marketing approach.

I begin by developing a comprehensive strategic marketing plan. This plan is based on the insights gathered during the diagnostic phase and is aligned with the company's overall business objectives. It outlines the key priorities, initiatives, and success metrics for the next 6-12 months. A critical component of this plan is a detailed customer journey map. By understanding how customers interact with the brand at every touchpoint, we can identify the biggest drop-off points and opportunities for improvement.

At this stage, I also work with the team to define a clear set of Key Performance Indicators (KPIs) and build a marketing dashboard for tracking progress. This ensures that everyone is aligned on what success looks like and provides a transparent view of our performance, which is essential for effective board-level reporting. When I worked with a large CPG company, we discovered that the team was tracking dozens of metrics, none of which were tied to business outcomes. By focusing on a few key KPIs, we were able to bring clarity and focus to our efforts. This often involves a deep dive into performance marketing metrics and optimizing our multi-channel marketing efforts. A crucial part of this is establishing a clear model for marketing attribution (Wikidata), so we can accurately measure the ROI of our campaigns.

This phase is also about securing the necessary resources and buy-in for our strategic initiatives. I present the marketing plan to the executive team, making a clear business case for the proposed investments. The credibility I've built in the first 30 days is crucial for getting the support I need. This is also the time to start implementing foundational projects, such as improving the marketing automation platform or launching a new content marketing program. For example, I might initiate a design sprint to rapidly prototype and test new ideas for a product launch, or begin the process of hiring a marketing team to fill any critical skills gaps.

Days 61-90: Scaling and Transferring Knowledge

The final phase of my 90-day plan is all about execution, optimization, and ensuring a smooth transition. This is where the strategic plan comes to life, and we start to see the results of our efforts. The focus is on launching and managing our strategic initiatives, continuously optimizing our campaigns, and scaling what's working.

I work closely with the team to ensure that we are executing effectively and staying on track to meet our goals. We have regular check-ins to review progress, address any challenges, and make adjustments as needed. I also develop a comprehensive content and communications plan to ensure that we are telling a consistent and compelling story across all channels.

As an interim CMO, one of my most important responsibilities is to ensure that the marketing team is set up for success long after I'm gone. This means documenting all of our processes, strategies, and learnings. I create a comprehensive marketing playbook that can be used by the team to continue executing effectively. I also invest time in training and empowering the team, ensuring they have the skills and knowledge they need to succeed.

In my final weeks, I prepare a detailed report for the executive team, summarizing our accomplishments, key learnings, and recommendations for the future. This provides a clear overview of the impact I've made and a roadmap for the marketing team to follow. My goal is to leave the marketing function in a much stronger position than when I found it, with a clear strategy, a high-performing team, and a robust marketing engine. This includes a thorough handover to the permanent marketing leader, ensuring they have all the information and resources they need to continue driving the marketing function forward. I also make sure to have a proper agency management process in place if the company is working with external partners.
