Bonus 13 — Financial Thinking for Managers

60-Second Summary

Bonus module 13 of the program (Critical Skills extension). Theme: Not accounting — business thinking.
Quarterly business case (1 page per major ask) — the ritual you install.
Same rhythm as weeks 1–12: pre-read, cohort live, ritual, falsifiable homework.
Closes a high-priority gap most new-manager programs ignore.

Every headcount request, every tool purchase, every project commitment is a financial decision your manager has to defend upward. Managers who can frame their asks in business terms get them approved; managers who can't get coached or denied. This module installs the framing.

What the evidence says

Finance-business-partner field research: requests that lead with ROI/payback approve at 2–3× the rate of those that lead with team need, even when the underlying merit is identical.
Hiring economics: a fully loaded engineer in a high-cost market is $250k–$400k/year — managers who run their team without a mental cost model under-invest in retention and over-invest in headcount asks.
Christensen (HBR): 'jobs to be done' framing translates directly to manager investment decisions — what job is this hire/tool/project being hired to do, and what does success look like?

Pre-read (60 minutes)

Read: the 5 numbers every manager should know about their team — fully loaded cost per head, attrition cost, hiring cost, tools budget, opportunity cost (20 min).
Read: ROI vs payback vs NPV — what each means and when to use which (15 min).
Read: the difference between OpEx and CapEx, headcount vs contractor budget, and why finance cares (15 min).
Reflect (10 min): your last headcount or tool request. Did you frame it financially? If not, why did it get approved (or did it)?

Live session (90 minutes)

Cohort flow with a senior coach

1
Cost-of-team exercise (20 min)
Each manager computes the fully loaded annual cost of their current team. Most are off by 30–50% (forget benefits, equity, employer taxes, tooling). Coach calibrates.
2
ROI memo template (20 min)
Coach walks through the 1-page investment memo: ask, cost (fully loaded), expected return (named in business terms), payback period, what would change the answer. Cohort drafts one for a real upcoming ask.
3
Opportunity cost drill (15 min)
Coach presents 3 paired choices (hire vs contract, build vs buy, this project vs that project). Cohort argues both sides using opportunity-cost framing. Counter-intuitive answers win.
4
Prioritisation with constraints (20 min)
Each manager lists their top 6 quarterly investments. Coach forces a stack rank with a budget cap. Most managers discover they have not actually prioritised — they have a wish list.
5
Wrap (15 min)
Each manager commits to one ROI memo for their next ask and one prioritisation conversation with their manager this month.

The ritual you install

Quarterly business case (1 page per major ask)

Before every quarterly planning cycle, write a 1-page business case for each major ask (headcount, tool, project). State the cost, the business outcome, the payback or ROI, the alternative considered, and what would change the answer. Submit before the planning meeting. Over time, your approval rate climbs and your finance/exec relationships strengthen.

Modern tools for this skill

Category	Examples (2026)	Use
People cost models	Pave, Carta, internal finance dashboards, simple spreadsheet	Know what your team actually costs
Business case templates	1-page investment memo, ROI calculator, payback worksheet	Lower the activation energy of writing one
Prioritisation	RICE (Reach, Impact, Confidence, Effort), ICE, Cost of Delay, WSJF	Force ranking when budget is tight
Finance partnership	Quarterly FP&A sync, named finance business partner	Build the relationship before you need it

Copy-paste AI prompt

I want to make a request: [hire / tool / project] for my team. Cost is approximately [amount or headcount]. The business problem it solves is [describe]. Help me: (1) compute the fully loaded cost over 12 months, (2) draft a 1-page business case using the standard ROI memo template, (3) name the most likely objections from finance and how to answer them, (4) suggest one cheaper alternative I should have considered.

Homework — falsifiable artefacts

Fully loaded cost of your current team computed and stored.
One ROI memo drafted for an upcoming ask.
Top quarterly investments stack-ranked with budget cap applied.
Finance business partner identified and 30-minute intro booked.

Success signal

By end of this module, you can state the fully loaded cost of your team in 10 seconds, your asks land with a 1-page business case rather than a Slack message, and finance starts treating you like a partner instead of a petitioner.

Reviewer notes

HR Director (15+ yrs)

Managers who think financially get promoted. It's not about being a numbers person — it's about respecting the fact that every yes to your team is a no to someone else's, and showing you understand the trade.

Line Manager (20+ yrs)

I wish someone had taught me ROI memos in my first year. I lost two budget fights in a row because I argued with passion instead of payback. The third one, I came with a memo and got everything I asked for plus more.

OB / HR Professor (25+ yrs)

Mintzberg distinguished between the entrepreneur role and the resource-allocator role of the manager. Both require financial framing — without it, the manager is a delivery function, not a leader. This is what an MBA actually teaches in one semester; you can install the floor in 90 minutes.
