Strategy consulting and implementation
Strategy consulting in Nigeria for boards and executive teams: corporate strategy, strategic plans, strategy retreats and the implementation discipline that turns a plan into results.
Strategy consulting for boards and executive teams in Nigeria
Most organisations in Nigeria do not lack a strategy document. They lack a strategy that survives contact with the operating environment: a currency that moves, costs that rise faster than prices, and a market that rewards speed over planning. Carthena Advisory works with boards and executive teams to make the few choices that matter, fund them properly and build the discipline to carry them through.
Our work answers three questions. Where should the organisation compete? How will it win there? What must it build, stop or buy to do so?
Corporate strategy
Corporate strategy decides where a group should invest, hold or exit. We assess each business on the value it creates, the capital it consumes and its position against competitors, then set out the portfolio choices, from growth investments and new markets to divestments. Where the choice is to enter a new market, the work continues into market entry and go-to-market strategy.
Strategic plans
A strategic plan earns its place only if it changes how resources are allocated. Ours start from a fact base on the market, the competition and the organisation's own economics, then narrow to a small number of priorities with owners, budgets and milestones. The plan typically covers 3 to 5 years, with targets for the first year set in the detail a management team can run against.
Strategy retreats and sessions
Many strategic plans are shaped in a few days away from the office. We design and facilitate strategy retreats for boards and senior management teams, prepare the fact base in advance, run the sessions so that disagreements are resolved on evidence, and turn the conclusions into a written plan within days rather than months.
Strategy implementation
Execution is where strategy succeeds or fails. We set up the governance that keeps a strategy moving: a small transformation office, a dashboard of the measures that matter, a monthly review rhythm and a clear process for escalating decisions. We build these inside the client's own teams, so the discipline remains after we leave.
Strategy in a volatile economy
A strategy built for Nigeria has to hold when the exchange rate, interest rates and input costs move sharply within a single year. We build each plan around a small number of scenarios, identify the signals that show which one is unfolding, and set in advance the decisions leadership will take if they appear. The organisation then adjusts on evidence rather than rewriting the plan every time conditions change.
Signs a strategy needs revisiting
- Revenue is growing, but margins and cash are not.
- The leadership team describes the priorities differently.
- Capital goes to whichever project is argued most loudly.
- The plan was written before the last devaluation or rate cycle and has not been tested since.
- New competitors are winning customers the business considered its own.
Strategy for public institutions
Public institutions face the same strategic questions under different constraints: a mandate set by law, budgets set by appropriation and stakeholders who measure success differently. We help ministries, agencies and government-owned enterprises turn their mandates into strategies they can deliver, alongside our institutional strengthening work.
How an engagement runs
- Diagnose. Market, competitive and financial analysis, with interviews across the leadership team.
- Choose. Options developed and tested with the board, usually through a facilitated strategy session.
- Plan. Priorities, owners, budgets, milestones and measures.
- Implement. Governance, dashboards and review support for the first year.
Why Carthena
Carthena Advisory has completed more than 70 projects in 12 sectors. Our strategy work is built on our Strategic Synergy Integration approach, which tests whether an organisation's beliefs, its structures and its people's capabilities support the strategy it has chosen, because most strategies fail where those three disagree. We pair it with economic intelligence on Nigerian and African markets, so every plan rests on a realistic view of the environment it must survive.

Nigeria does not have a planning problem. It has a strategy problem.
Nigeria keeps writing national agendas and abandoning them. The fix is not another plan but an economic identity, three choices, and the discipline to hold them.

How to Run High-Impact Strategy Sessions Using a Powerful SWOT Framework
A SWOT analysis is only as valuable as the quality of the conversation it generates. In the wrong hands it produces a list. In the right hands it produces a decision. The difference lies in the facilitation - and in knowing what to do with the output.

Why Nigerian Boards Need Commercial Resilience Diagnostics
Most Nigerian boards can tell you their revenue. Few can tell you how much of it will survive the next market disruption. Commercial resilience diagnostics are no longer optional - they are the missing instrument in board-level governance.

How much does strategy consulting cost in Nigeria?
Carthena prices each engagement as a fixed fee, agreed after a scoping conversation. The fee depends on the scope of the strategy, the number of businesses or units involved, the depth of market research and whether implementation support is included. A facilitated strategy retreat can be priced on its own.
How long does it take to develop a strategic plan?
A full strategic plan typically takes eight to twelve weeks from diagnosis to an approved plan. A strategy retreat, including preparation of the fact base and the written output, typically takes three to four weeks.
Do you facilitate strategy retreats?
Yes. Carthena designs and facilitates strategy retreats for boards and senior management teams. We prepare the fact base in advance, run the sessions and deliver a written plan with priorities, owners and timelines shortly after.
What is the difference between a strategy and a strategic plan?
A strategy is the set of choices about where to compete and how to win. A strategic plan turns those choices into priorities, budgets, owners and milestones over a fixed period. An organisation can have a plan without a strategy, which is why we settle the choices first.
Do you stay involved after the strategy is approved?
If the client wants us to. Many engagements include implementation support for the first year: setting up the transformation office, the dashboard and the review rhythm, and supporting the first quarterly reviews.
