What does a Chief Strategy Officer do?

A Chief Strategy Officer (CSO) owns the end-to-end strategy lifecycle: shaping the corporate strategy with the CEO and board, cascading it into objectives, KPIs and initiatives, running the Strategy Management Office, and holding the enterprise accountable to measurable execution.

Who does the CSO report to?

In most enterprises the CSO reports directly to the CEO and has a dotted line to the board's strategy committee. In GCC governments the equivalent role reports to the Minister, Governor or Managing Director and coordinates with the national vision realization office.

What is a Strategy Management Office (SMO) charter?

An SMO charter is the founding document that defines the SMO's mandate, scope, decision rights, governance cadence, KPIs and interfaces with the EPMO, finance and business units. It is signed off by the CEO and board and reviewed annually.

Chief Strategy Officer: Responsibilities & SMO Charter

The Chief Strategy Officer is the enterprise's strategy-to-execution conscience. This guide covers the CSO's core responsibilities, reporting lines, KPIs, first-100-days plan, and a ready-to-adapt Strategy Management Office charter template.

What a Chief Strategy Officer actually owns

Below the title, the CSO owns three interlocking mandates: shaping strategy, running the operating rhythm that executes it, and holding leadership accountable to the numbers that prove it. Titles vary — Head of Strategy, VP Strategy, Group Strategy Director — but the mandate is the same.

Core responsibilities

Corporate strategy formulation. Facilitate the strategy cycle with the CEO and board — environmental scans, Porter's Five Forces, GE-McKinsey, scenario planning, and long-range financial modelling.
Cascade & alignment. Translate the corporate strategy into a strategy cascade with owned objectives, KPIs and initiatives at group, business-unit and function level.
Portfolio prioritization. Own the strategic portfolio — which bets are funded, paused or killed each quarter.
Performance rhythm. Run the monthly and quarterly business reviews with a single source of truth, not slide decks rebuilt every cycle.
Governance. Chair or convene the strategy committee, steer stage-gate approvals, and enforce change control on strategic commitments.
M&A and partnerships. Lead corporate development, inorganic growth theses, integration strategy and benefits realization.
Strategic risk. Maintain the enterprise strategic risk register and ensure top risks tie back to specific objectives.
Board-ready insight. Own the strategy narrative that reaches the board — variance, forecasts, decisions required.

Reporting lines & organisational placement

Solid line: Chief Executive Officer (or, in GCC governments, the Minister / Governor / Managing Director).
Dotted line: Board strategy committee or, at country level, the national vision realization office.
Direct reports: Head of SMO, Head of EPMO (or coordinated peer), Head of Corporate Development, Head of Strategic Analytics.

KPIs the CSO is measured on

Strategic objective attainment rate (% on track)
Initiative benefit realization vs. business case
Portfolio funding aligned to top-tier objectives (%)
Cycle time from decision to funded initiative
Board / executive confidence in strategy execution (survey)
Strategic risk coverage: top risks with owned mitigations

The first 100 days

Days 1–30 — Diagnose. Interview the CEO, board chair, business-unit heads and finance. Audit the current strategy, cascade, portfolio and governance forums. Stand up a single source of truth.
Days 31–60 — Align. Publish a draft SMO charter, confirm objectives, appoint owners, agree the review cadence, rebaseline KPIs.
Days 61–100 — Execute. Run the first quarterly business review under the new operating model, publish decisions, reallocate funding to the top-priority initiatives.

Strategy Management Office (SMO) charter — template

Adapt the sections below into a single 1–2 page document, sign it off with the CEO and board, and refresh annually.

Purpose. Why the SMO exists — turn strategy into measurable, auditable execution.
Scope. Corporate strategy, cascade, performance management, strategic portfolio, benefits, strategic risk, governance, M&A support.
Decision rights. What the SMO decides, recommends, consults on, and is informed of (RACI at document level).
Governance cadence. Monthly performance review, quarterly business review, annual strategy refresh, ad-hoc change control.
Interfaces. With EPMO, finance, HR, risk, business units and — where relevant — the national vision office.
KPIs of the SMO itself. Objective attainment, benefits realization, portfolio alignment, decision cycle time.
Team & tooling. Roles, skills mix, and the strategy execution platform of record.

CSO vs Head of EPMO vs COO

CSO owns the what and the why — the strategy and the outcomes.
Head of EPMO owns the how at portfolio and programme level — delivery mechanics.
COO owns the day-to-day — running the business at operational cadence.

These roles collide badly without a shared operating model and a single source of truth. That is the SMO's job to enforce.
