The Fractional Executive Onboarding Playbook

1. Why This Playbook Exists

Fractional executives are one of the highest-value hires a growing company can make. They bring 15 to 25 years of experience, work part-time, and cost a fraction of a full-time C-suite salary. LinkedIn profiles mentioning "fractional" alongside a C-suite title grew from roughly 2,000 in 2022 to over 110,000 by late 2024, and the fractional workforce has roughly doubled in that same period.

But most companies treat onboarding a fractional executive the same way they'd onboard a consultant or a new full-time employee. Neither works. Consultants advise from the outside. Employees ramp over months. A fractional executive needs to lead from day one, with real authority, a clear scope, and outcomes they can actually be measured against.

When the setup is vague, the engagement fails. There's no large-scale study on fractional executive failure rates specifically, but the data on executive hiring failure in general is well established. Heidrick & Struggles analyzed 20,000 of their own placements and found that 40% of senior executives are pushed out, fail, or quit within 18 months. A Leadership IQ study tracking 5,247 hiring managers found a 46% failure rate, with only 19% achieving clear success. These studies are from roughly 2006 to 2009 and focus on full-time hires. But the causes they identified (cultural misfit, relationship problems, unclear expectations) don't go away because someone works part-time. If anything, the compressed timeline of a fractional engagement leaves less room to recover from a bad start. [See Sources, Chapter 14]

For full-time hires, that pattern gets expensive. The Center for American Progress found that replacing a senior executive costs up to 213% of their annual salary once you factor in search fees, severance, and organizational disruption. Fractional engagements don't carry that same financial risk. You have a 30-day termination clause, not a severance package. But the real cost of a failed fractional hire is the runway you burned while nothing got built. Two or three months of retainer fees plus the opportunity cost of problems that didn't get solved. For a startup burning $200K a month, that delay matters.

What makes it worse is how few companies take onboarding seriously. Gallup's research shows that only 12% of employees feel their company does a great job of onboarding. For executives specifically, a 2022 Harvard Business Review article found that fewer than 2% of companies address executive integration in any systematic way. Meanwhile, Boston Consulting Group surveyed 4,288 respondents across 102 countries and found that companies with strong people management practices, including onboarding and retention, saw 2.5 times the revenue growth and nearly double the profit margin of companies that didn't invest in those areas.

This playbook exists to close that gap.

What follows covers everything from defining the role and structuring the engagement through the first 90 days, KPI frameworks, red flags, and transition planning. Every recommendation is backed by named research, and every source is listed in Chapter 14 so you can check our work.

Whether you're hiring your first fractional CFO or thinking about building out a full fractional C-suite, keep this guide close.

2. The Fractional Executive Model, Explained

A fractional executive is a senior leader, typically with 15 or more years of experience, who works part-time for your company on a contract basis. They hold the same title and responsibilities as a full-time C-suite executive (CFO, COO, CMO, CRO, CTO), but they work 10 to 30 hours per week instead of 40 or more.

This isn't consulting. A consultant advises and leaves. A fractional executive leads your team, makes decisions, and owns outcomes. But it's also not full-time leadership at a discount. A fractional CFO working 15 hours a week can build your financial infrastructure, but they're not going to be in every meeting or available for every fire drill. The model works because experienced executives know how to prioritize. Just don't expect 40 hours of output from 15 hours of work.

Why the Model Is Growing

The fractional workforce has roughly doubled since 2022, growing from an estimated 60,000 to 120,000 professionals globally according to industry data from Fractionus and the Frak Conference. Cerius Executives, a placement firm, reported 68% year-over-year demand growth for fractional CMOs, CFOs, and CTOs from 2023 to 2024. Job postings mentioning fractional work have tripled since 2018.

A few things are driving this:

• Cost: A full-time CFO costs $250,000 to $500,000+ per year in total comp. A fractional CFO addresses the same core strategic priorities for $3,000 to $12,000 per month, depending on scope and hours.
• Talent: Nearly three out of four fractional professionals (72.8%, per a Vendux survey) have 15+ years of experience. These aren't junior people freelancing between jobs. They're career executives who've deliberately chosen a portfolio model.
• A gap in the market: HBR found that fewer than 2% of companies handle executive onboarding in any structured way. That creates an opening for experienced operators who can drop into a role and create order quickly.

The Cost Comparison

For a growth-stage company, here's what the numbers actually look like (based on data from the Bureau of Labor Statistics, Pilot, and Burkland Associates):

Burkland Associates estimated that a $10M ARR startup saves over $500,000 a year by going fractional instead of full-time on the CFO role. That's real runway. One caveat: the per-hour rate for a fractional executive is higher than the blended rate of a full-time hire. You're paying a premium for flexibility and experience density. The savings come from buying fewer total hours, not cheaper hours.

Fractional vs. Interim vs. Full-Time

These are three different engagement types. Choosing the wrong one leads to misaligned expectations.

3. Before You Hire: Defining What You Actually Need

Before you start interviewing candidates, you need to answer four questions. Get these wrong and even the best executive will struggle.

Question 1: What Problem Are You Solving?

Be specific. "We need help with finance" isn't a problem statement. "We're burning cash faster than projected and we don't have visibility into our unit economics" is a problem statement.

Common reasons companies hire fractional executives:

• Cash is running out faster than planned and nobody can explain why
• You're preparing to raise capital and the books aren't investor-ready
• Revenue has plateaued and the sales process is undefined
• Operations are chaotic and the founder is stuck in day-to-day firefighting
• Marketing spend is increasing but pipeline isn't growing proportionally
• A key leader just left and you need experienced coverage now, not in three months

Question 2: Which Role Do You Need?

This matrix helps you match the problem to the role:

Question 3: What Does Success Look Like in 90 Days?

Write this down before you interview a single candidate. If you can't articulate what a successful engagement looks like in 90 days, you're not ready to hire.

Good examples:

• "Our monthly close is under 7 days and we have a 12-month rolling forecast."
• "We have a documented sales process and our pipeline coverage ratio is above 3x."
• "Our operating cadence is running without me in every meeting."

Bad examples:

• "Help us with our strategy."
• "Figure out why things feel slow."
• "Get our finances in order."

Question 4: Are You Ready to Transfer Authority?

This is the question most companies skip, and it's the one that matters most.

Korn Ferry surveyed executives and found that the top reason new hires leave within 6 months is that the role turned out to be different from what they were told during hiring. For fractional executives, this almost always comes down to authority. If you give someone the title of CFO but they can't approve a vendor payment without going through you first, you haven't created a leadership role. You've created a bottleneck.

Before you hire, be honest with yourself. Are you willing to let someone else make decisions in this area? If the answer is "no, not really," you don't need a fractional executive. You need a consultant or advisor.

4. Structuring the Engagement

A clear engagement agreement protects both sides. Skip this and you'll spend the first month arguing about scope instead of doing the work.

Scope of Work

Spell out exactly what the executive will own, what they'll advise on, and what falls outside the engagement. A scope that says "all things finance" is a recipe for frustration. A scope that says "build a monthly close process, create a 12-month forecast, and prepare the company for Series A due diligence" is actionable.

Time Commitment

Match the hours to the scope:

Duration and Terms

Most fractional engagements start with a 3-month initial term, which gives both sides enough time to establish baselines and measure results. The specific terms are between you and the executive. Work with your attorney to structure something that protects both sides.

Your engagement agreement should cover the basics: scope of work, time commitment, duration, termination terms, decision-making authority, confidentiality, and worker classification. We're not going to tell you what those terms should be. That's between you, the executive, and your attorney.

One thing worth flagging: most fractional executives work as independent contractors (1099), but the classification has to reflect the actual working relationship, not just what the contract says. The IRS has specific guidance on this at irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee. Have an employment attorney review the arrangement before day one. This isn't optional. Misclassification carries real penalties.

Authority Transfer

This is where most engagements go sideways. If you hire a CFO with 20 years of experience and then require them to get approval before paying a vendor invoice, you haven't hired a CFO. You've hired an expensive bookkeeper.

That said, let's be honest about the other side. You're giving real authority to someone who holds no equity in your company, works for other clients, and can leave with 30 days' notice. That's a legitimate risk. The way to manage it isn't to withhold authority (that kills the engagement). It's to define the boundaries clearly, start with a smaller scope of authority in Month 1, expand it as trust builds, and keep enough visibility through weekly check-ins that you'd catch a problem early.

That said, you do need to be explicit about the boundaries. Not because the executive needs a permission slip, but because your team needs to know who can make what call. Have the conversation before day one, and put the answers in a short written document (even a one-page email works). Verbal agreements get forgotten or reinterpreted. Written ones don't. Cover these four things:

• What decisions the executive owns outright (most things in their domain)
• What decisions need a quick heads-up to the CEO (hires, large expenses, vendor changes)
• What the CEO still wants to approve personally (usually very few things)
• How the executive's role and authority will be explained to the team

The goal is clarity, not control. If your list of "CEO must approve" items is longer than your list of "executive owns," you're micromanaging. Revisit the scope or hire a consultant instead.

5. The Pre-Start Checklist

Everything on this list should be completed before the executive's first day. If they show up and spend the first week chasing logins and asking for org charts, you've already wasted 20% of their first month.

Gallup's research found that only 29% of new hires feel fully prepared to do their job after onboarding. For a fractional executive working 10 to 30 hours a week, every hour matters. Don't make them spend it chasing access requests.

Systems and Access

• ☐ Email account created and configured
• ☐ Slack, Teams, or primary communication tool access granted
• ☐ Calendar access (shared calendar with CEO and leadership team)
• ☐ Project management tool access (Notion, Asana, Linear, etc.)
• ☐ Role-specific tools (accounting software, CRM, analytics dashboards, etc.)
• ☐ Document repository access (Google Drive, SharePoint, Dropbox)

Documents to Prepare

• ☐ Current org chart with roles and reporting lines
• ☐ Most recent financial statements (P&L, balance sheet, cash flow)
• ☐ Current budget or forecast (even if rough)
• ☐ Pitch deck or investor materials (if raising)
• ☐ Key contracts and vendor agreements
• ☐ Product or service overview documentation
• ☐ Customer list or CRM export
• ☐ Team bios with roles and tenure

Internal Communication

Before the executive starts, send a message to your team that covers:

• Who this person is (role, not personal details)
• Why you brought them on (the specific problem they're solving)
• What authority they have (what they can decide, what still goes through you)
• How the team should interact with them (meeting cadence, communication channels)

6. Week 1: Rapid Immersion

The first week sets the tone for the entire engagement. But let's be honest about the math. If your fractional executive is working 15 hours a week, "Week 1" means 15 hours of actual time. That's not five full days. It's closer to two. Everything below should be scaled to the hours you're actually paying for.

A Texas Instruments study (reported by the SHRM Foundation) showed that structured onboarding got new hires to full productivity two months faster than their old approach. For a fractional engagement that might only last three to six months, that acceleration matters even more.

The Kickoff (90 Minutes)

Start with a focused kickoff session with the CEO. Keep it to 90 minutes. Cover:

1. The top 3 problems you're hiring them to solve
2. What success looks like in 30, 60, and 90 days
3. Who the key stakeholders are and what they expect
4. What's been tried before and why it didn't work
5. Any landmines, politics, or sensitivities to be aware of

Stakeholder Conversations (3 to 5 Hours)

The executive should meet one-on-one with every direct report and 2 to 3 key cross-functional leaders. Keep these to 30 minutes each. They're listening for patterns, not conducting audits.

For each conversation:

• What's working in that person's area
• What's broken or frustrating
• What they wish leadership would do differently

Data Review (3 to 5 Hours)

After the conversations, the executive reviews the relevant data. This happens in parallel with meetings, not as a separate phase. What they look at depends on the role:

• CFO: Financial statements, bank accounts, AR/AP aging, burn rate
• COO: Process maps, team utilization, project status
• CRO: Pipeline data, conversion rates, sales cycle length
• CMO: Marketing spend, CAC, channel performance
• CTO: Codebase, architecture docs, deployment pipeline, incident history

End of Week 1: A Written Point of View (2 to 3 Hours)

With the remaining hours, the executive should write up a brief take on what they've observed. Not a 20-page report. A page or two covering:

• What stands out, good and bad
• Quick wins they can deliver in the next 2 to 3 weeks
• Deeper issues that will take longer
• Any adjustments needed to the original scope

At 15 hours a week, that's roughly: 1.5 hours for the kickoff, 3 to 5 hours for stakeholder meetings, 3 to 5 hours reviewing data, and 2 to 3 hours writing it up. It fits. At 10 hours a week, the stakeholder meetings and write-up may spill into the second calendar week, and that's fine.

7. The 30-60-90 Day Framework

McKinsey's Scott Keller and Mary Meaney found that 92% of externally hired executives take more than 90 days to reach full productivity. 62% said it took them at least six months to have real impact. A fractional executive working 15 to 25 hours a week doesn't get that kind of runway.

That's why the 30-60-90 day framework matters. Michael Watkins popularized it in The First 90 Days (Harvard Business School, now in its second edition and over a million copies sold). The arc maps onto fractional engagements, but you have to adjust the scope to the hours. A fractional executive working 20 hours a week has roughly 80 hours in a month. That's two full-time weeks. Set your expectations accordingly. The milestones below assume a "Standard" engagement of 20 to 30 hours per week. Scale them down for lighter engagements, up for intensive ones.

Days 1 to 30: Understand the Current State

The first month is about understanding what you have, identifying the biggest gaps, and delivering one or two quick wins that build trust with the team.

Realistic milestones for a 20 to 30 hour/week engagement:

1. Complete assessment of current state (systems, people, processes)
2. Identify the top 3 to 5 priority areas
3. Deliver at least 2 quick wins (visible, measurable improvements)
4. Present a 90-day roadmap with specific deliverables and timelines
5. Establish reporting cadence and KPI dashboard

Days 31 to 60: Build the Systems

Month 2 is where the real work happens. The executive moves from understanding to building, putting in place systems and processes that didn't exist before.

Milestones by end of Month 2:

1. Core systems built or significantly improved
2. Team aligned around goals with clear ownership and accountability
3. New meeting cadences, workflows, and tracking in place
4. Early wins compounding into measurable business impact
5. Stakeholder confidence increasing (team knows what's happening and why)

Days 61 to 90: Prove It Works

By Month 3, the systems from the previous month should be running. Now the executive is fine-tuning, measuring results, and demonstrating that the investment is paying off.

Milestones by end of Month 3:

1. All primary objectives either achieved or on a clear trajectory
2. Operational cadence running without daily CEO involvement
3. KPI dashboard showing measurable improvement from baseline
4. Team capable of maintaining what's been built
5. Decision made on engagement renewal, expansion, or transition

The 90-Day Review

At the end of 90 days, conduct a formal review covering:

• What was accomplished vs. what was planned
• KPI movement from baseline
• ROI analysis (value delivered vs. cost of engagement)
• Team feedback (is this person making the org stronger?)
• Next phase recommendation: renew, expand, convert to full-time, or wind down

8. The Role-by-Role Onboarding Guide

The 30-60-90 arc applies to every fractional role, but what happens in each month depends on the function. The roadmaps below assume a Standard engagement (20 to 30 hours per week).

If your engagement is lighter (10 to 15 hours a week), don't just stretch these timelines. Cut the scope. A 10-hour COO can't build an operating cadence, redesign your project management system, and implement OKRs all in the same quarter. Pick the one thing that matters most and let them focus. A narrower scope done well beats a broad scope done halfway.

As a rough guide for a 10 to 15 hour/week engagement: a fractional CFO should focus on getting the monthly close clean and building a basic forecast, not on scenario planning or investor materials in the same quarter. A fractional COO should pick one broken process and fix it, not try to redesign the whole operating cadence. A fractional CRO should audit the pipeline and fix the sales methodology, not also rebuild comp plans and territory maps. A fractional CMO should nail positioning and one or two channels, not launch a full go-to-market strategy. A fractional CTO should focus on the biggest technical risk (security, scalability, or architecture) and fix the deployment pipeline, not try to overhaul everything at once. Talk to your executive in Week 1 about what's realistic given the hours, and agree on what's in and what's out.

Fractional CFO

Month 1: Financial system audit. Clean up the chart of accounts. Assess the accuracy of current reporting. Identify cash flow risks. Deliver a preliminary monthly close process.

Month 2: Build or upgrade accounting systems. Create a 12-month rolling forecast. Establish budget vs. actual reporting. Strengthen financial controls (vendor approvals, expense policies, segregation of duties).

Month 3: Scenario planning (what-if models for growth, fundraising, or downturn). Investor-ready financial package. Board deck with clean metrics. KPIs embedded in weekly leadership rhythm.

Key deliverables: Monthly close under 7 days, accurate 12-month forecast, cash runway visibility, investor-ready financials.

Fractional COO

Month 1: Observe current operations. Conduct internal interviews. Map existing processes. Identify the top 20 to 30 improvement areas and prioritize the top 5.

Month 2: Build new meeting cadences. Define decision rights and escalation paths. Create operational dashboards. Introduce accountability frameworks (OKRs or similar).

Month 3: Reliable operating cadence running company-wide. Cross-functional processes documented. Team executing without daily founder intervention. Scalable systems in place.

Key deliverables: Operating cadence, decision-rights matrix, process documentation, team accountability system.

Fractional CRO

Month 1: Audit the sales process end-to-end. Review pipeline health, conversion rates, and rep performance. Assess CRM data quality. Map the buyer journey.

Month 2: Define or refine the sales methodology. Build a pipeline coverage model. Set up basic sales forecasting. Start rep coaching cadence.

Month 3: Pipeline coverage ratio improving (target 3x). Forecast accuracy getting tighter. Rep performance tracked and coached weekly. Marketing-to-sales handoff defined.

Key deliverables: Documented sales process, pipeline model, forecast framework.

Fractional CMO

Month 1: Brand and marketing audit. Review positioning, messaging, and competitive landscape. Assess channel performance and marketing spend efficiency. Define ICP and buyer personas.

Month 2: Develop positioning and go-to-market strategy. Pick one or two channels and launch initial campaigns. Start tracking attribution (even if basic). Begin aligning with sales on lead definitions.

Month 3: Campaigns running and producing data. Positioning documented and shared. Marketing-sales handoff process in place. CAC baseline established (improvement comes later).

Key deliverables: Positioning document, go-to-market strategy, campaign performance baseline, ICP documentation.

Fractional CTO

Month 1: Get oriented in the codebase and infrastructure. Meet the engineering team. Identify the single biggest technical risk (security, scalability, or reliability) and the most urgent process gap. You won't audit everything in Month 1. Focus on understanding what's most likely to break.

Month 2: Establish engineering processes (code review, deployment pipeline, sprint cadence). Create a technical roadmap aligned to business priorities. Start addressing the highest-risk technical debt.

Month 3: Engineering velocity improving. Deployment frequency up, incident rate down. Technical roadmap being executed against. Team confident in the architecture direction.

Key deliverables: Technical architecture document, engineering process improvements, technical roadmap, risk assessment.

9. KPI Frameworks by Role

If you don't have a KPI dashboard by the end of Month 1, the engagement is already off track. The executive needs numbers to manage against, and you need numbers to hold them accountable.

That said, be honest about which metrics can actually move in 90 days of part-time work and which ones can't. Monthly close time, pipeline coverage ratio, and forecast accuracy are process metrics. A good fractional executive can improve those within a quarter. CAC, gross margin, and revenue growth are outcome metrics. Those take 6 to 12 months to shift, regardless of how good the executive is.

Don't give your executive a free pass on results. But don't hold them accountable for outcomes that require time they haven't had yet. If your fractional CRO has rebuilt the pipeline model and coverage is at 3x by Month 3, the revenue will follow. If they haven't built anything and they're telling you to wait, that's a different conversation.

10. Meeting Cadence and Communication

Get the communication wrong and you'll either micromanage or lose track of what's happening. Neither is good. The goal is a rhythm that keeps you informed without burning hours you're paying for on status meetings.

Be careful here. If your fractional executive is working 15 hours a week and you schedule 5 hours of recurring meetings, you've just spent a third of their capacity on talking instead of doing. The cadence below is a starting point. Adjust it to your engagement level. A 10-hour-a-week advisory engagement might only need a biweekly CEO sync and a monthly review. A 30-hour intensive engagement can support a fuller schedule.

The Non-Negotiables (Every Engagement)

That's it for a 10 to 15 hour engagement. A weekly 30-minute check-in and a monthly deep dive. Total meeting overhead: about 2 hours a month. Everything else is optional and should only be added if the hours support it.

Additional Cadence for 20+ Hour Engagements

Communication Norms

Set these expectations on day one:

• Response time: 24 hours for non-urgent items, 2 hours for urgent
• Primary channel: Slack or email (agree on one, don't split communication)
• Escalation path: What counts as an emergency and how to reach the executive
• Status updates: Weekly email summary of key activities, decisions, and next steps
• Shared workspace: All documents, notes, and deliverables in a single shared location

The Weekly Status Update

Every fractional executive should send a brief weekly update covering:

1. What was accomplished this week
2. Key decisions made (and rationale)
3. Blockers or risks that need CEO attention
4. Plan for next week
5. Any scope or timeline changes to flag

This should take 10 minutes to write and 2 minutes to read. If it takes longer, it's too detailed.

11. Red Flags and Course Correction

Some engagements don't work. That's reality. The difference between a recoverable rough patch and a wasted quarter is how quickly you spot the warning signs.

Red Flags During the First 30 Days

Red Flags During Months 2 to 3

• Pretty reports but no operational change (reporting theater)
• Building dependency on themselves rather than systems the team can run
• KPIs not moving in the right direction with no clear explanation
• Team morale declining instead of improving
• Scope creeping without discussion or approval
• Inability to acknowledge what isn't working

The Course Correction Conversation

When something feels off, don't wait. Have the conversation the same week. Start with what you're seeing (specific behaviors, not feelings) and the impact it's having. Then ask for their side. There's almost always context you're missing. Agree on what changes, by when ("by Friday" not "soon"), and set a follow-up to see if it worked.

If the issue persists after two direct conversations, it's time to end the engagement. Your termination clause exists for exactly this reason.

12. Transition Planning

Every fractional engagement has an endpoint. Whether the executive transitions to full-time, hands off to an internal hire, or completes the engagement, you need a plan.

Option 1: Convert to Full-Time

If the fractional executive is the right long-term fit, conversion is straightforward:

• Have the conversation early (Month 2 or 3), not at the last minute
• Give them 30 to 60 days' notice to adjust other client commitments
• Phase in increased hours before the official start date
• Address the classification change (independent contractor to W-2)
• Consider a 90-day probationary period with full benefits at the end

Most founders make the fractional-to-full-time transition somewhere between $10M and $25M in annual revenue, according to K38 Consulting's startup salary data. Below that, fractional typically makes more financial sense.

Option 2: Hire a Full-Time Replacement

If you're hiring someone else for the permanent role:

• Involve the fractional executive in the hiring process (they know what the role needs now)
• Plan a 30-day overlap between the fractional executive and the new hire
• The fractional executive should onboard the new hire using this same playbook
• All processes, frameworks, and institutional knowledge should be documented before exit

Option 3: Complete the Engagement

If the scope is done and you don't need an ongoing executive in this role:

• Begin the knowledge transfer 60 days before the planned exit
• Identify the internal person who will own each area (the "number 2")
• Run a "test week" where the executive steps back and the team operates independently
• Document everything: processes, frameworks, templates, contacts, historical context
• Schedule a final handoff meeting with all stakeholders

The Exit Readiness Checklist

Before the fractional executive departs, verify:

• ☐ All frameworks and processes are documented
• ☐ Authority has been transferred to the successor
• ☐ External relationships have been transitioned
• ☐ Templates and tools have been shared with the team
• ☐ The team can articulate the strategy independently
• ☐ KPI dashboards and reporting are self-sustaining

13. Checklists and Quick Reference

Use these checklists as quick reference guides throughout your engagement.

Pre-Hire Decision Checklist

• ☐ Problem statement clearly defined (specific, not vague)
• ☐ Correct role identified (CFO vs. COO vs. CRO vs. CMO vs. CTO)
• ☐ Engagement type selected (fractional vs. interim vs. full-time)
• ☐ 90-day success criteria written down
• ☐ Budget approved and engagement terms agreed
• ☐ Authority transfer boundaries defined

Week 1 Checklist

• ☐ 90-minute CEO kickoff completed
• ☐ All stakeholder 1-on-1 meetings scheduled and completed
• ☐ Data deep dive completed for relevant area
• ☐ Written initial assessment delivered to CEO
• ☐ Quick wins identified
• ☐ Communication cadence established

Monthly Health Check

• ☐ KPIs trending in the right direction
• ☐ Deliverables being completed on schedule
• ☐ Team engagement positive (no morale issues)
• ☐ Authority being exercised appropriately
• ☐ Communication cadence being maintained
• ☐ No red flags present
• ☐ Scope still aligned with original objectives

Engagement ROI Calculator

At the end of each quarter, calculate the engagement ROI using this formula:

Measurable improvements might include:

• Revenue directly attributed to new systems (CRO/CMO)
• Cost savings from improved processes (COO)
• Cash preserved through better financial management (CFO)
• Time saved by CEO no longer doing this function
• Problems prevented (risks the executive identified and addressed before they became costly)
