Sharp thinking starts with using clear frameworks to structure your thinking.
Whether you’re solving a client’s problems, crafting a growth strategy, sharpening your investment thesis, or deciding where to focus your time, the right mental model can help you focus on what matters, and cut through the noise.
The late Charlie Munger once said, “You’ve got to have models in your head. And you’ve got to array your experience on this latticework of models”.
This page curates the most useful mental models in consulting and business. Each one provides insights that you can use to make better decisions, craft more thoughtful strategies, or accelerate progress towards your goals.
Decision Making & Goal Setting
The Coin Flip is a deceptively simple decision-making technique that helps uncover your true preferences. By assigning an option to heads or tails and flipping a coin, you prompt an instinctive emotional response—relief or disappointment—when the coin lands. That reaction reveals what you really want, even if your logic has been clouded by overthinking and analysis paralysis. For example, a consultant deciding between two job offers—one with prestige, the other with better work-life balance—might feel an unexpected pang of regret when the coin favours the “prestigious” path. That feeling is useful data.
Cost Benefit Analysis is a foundational decision-making tool that weighs the expected costs of an action against its anticipated benefits. If the benefits outweigh the costs, the action is considered worthwhile. For instance, a council evaluating whether to build a light rail extension might calculate the upfront cost, ongoing maintenance, and disruption, and weigh that against long-term gains in reduced traffic congestion, increased property values, and carbon savings. The tool helps decision-makers stay grounded in economic rationality, especially when projects involve trade-offs or public funds.
The Priority Matrix (also known as the Impact–Effort Matrix) is a decision tool that helps teams focus resources by categorising tasks into four quadrants: Quick Wins (high impact, low effort), Major Projects (high impact, high effort), Fill-ins (low impact, low effort), and Time Wasters (low impact, high effort). A product team planning their next sprint might use the matrix to decide between building a complex analytics dashboard or fixing a simple but annoying UI bug. If the bug fix is a Quick Win, it gets fast-tracked. The matrix drives strategic focus, cutting noise and surfacing what really matters.
SMART Goals turn vague ambitions into concrete plans by requiring your goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. This structure forces clarity and accountability, making goals easier to track and accomplish. For instance, rather than saying “I want to improve client retention” a SMART version might be: “Increase client retention from 75% to 85% over the next 6 months by implementing a monthly check-in system”.
The Value GROW Model is a coaching and goal-setting framework built around five stages: Values (what matters most), Goals (what you want to achieve), Reality (where you stand now), Options (possible paths forward), and Way Forward (your action plan). It’s often used by mentors, leaders, or consultants working through performance issues or personal development. For instance, a project manager struggling with team dynamics might clarify that their Value is collaboration, their Goal is stronger team cohesion, and their Reality is frequent miscommunication. The GROW structure turns abstract frustration into practical progress.
Finance & Investing
The 5 C’s of Credit—Character, Capacity, Capital, Collateral, and Conditions—are the bedrock of credit analysis, used by lenders to assess a borrower’s reliability and overall credit risk. Each “C” offers a different lens: Character refers to trustworthiness; Capacity to the ability to repay; Capital to personal investment; Collateral to assets pledged; and Conditions to external factors like the strength of the economy. A bank evaluating a small business loan might look at the owner’s credit history (Character), revenue projections (Capacity), equity contribution (Capital), existing assets like land and equipment (Collateral), and industry outlook (Conditions) before making the loan.
Net Present Value (NPV)
NPV is a foundational tool in finance for evaluating the profitability of an investment by discounting future cash flows to their present value and subtracting the initial investment. A positive NPV means the project is expected to create value. It’s essential in corporate finance, from evaluating capital projects to mergers and acquisitions. For example, a mining company might estimate the lifetime cash flows of a new site, discount them at an appropriate rate, and compare the result to the upfront exploration cost. NPV helps them decide whether to dig, or walk away.
Management & Operations
The McKinsey 7 S Framework helps organisations align their internal elements by examining seven interconnected factors: Strategy, Structure, Systems, Shared Values, Skills, Style, and Staff. It’s a powerful diagnostic tool for guiding change management or post-merger integration. For example, a growing tech company expanding into international markets might discover that while their Strategy and Structure are sound, their internal Systems and cross-cultural Staff training are lagging—misalignment that could undermine execution. The 7 S model ensures leaders don’t just shift boxes on an org chart, but harmonise the whole system.
PPP Model (People, Process, Place)
The PPP Model is a human-centred framework often used to improve service experiences, particularly in healthcare and education. It focuses on the interactions between People (staff and users), Process (how services are delivered), and Place (the physical or virtual environment). For instance, a hospital aiming to reduce patient stress might use the PPP lens to train reception staff for better empathy (People), streamline check-in procedures (Process), and redesign waiting areas to be quieter and more calming (Place). It’s a reminder that great service is never just procedural—it’s personal and environmental, too.
The 9 M’s Resource Audit is a strategic framework that scans a firm’s internal capabilities by assessing nine key resource categories: Materials, Machinery, Make-up (brand/image), Management, Management Information, Markets, Men (human capital), Methods, and Money. It’s often used during strategic reviews, business turnarounds, or due diligence processes. For instance, a retail chain facing declining margins might audit its Methods (operational processes), Markets (customer segments), and Management Information systems to uncover inefficiencies or missed opportunities. Think of it as an X-ray for business infrastructure.
The Profitability Framework breaks down profit into its two core drivers: revenue and costs. It’s a go-to tool for consultants diagnosing underperformance, allowing them to zero in on whether declining profits stem from falling prices, lower volumes, rising fixed costs, or bloated variable costs. For example, a restaurant chain suffering shrinking margins might discover that while foot traffic is stable, rising food delivery commissions have quietly eaten into variable costs. The framework simplifies complex operations into a manageable equation—Revenue minus Cost—so you can target the right lever.
Value Chain Analysis maps all the activities a firm performs to deliver a product or service, from inbound logistics to after-sales service, and identifies where value is added—or lost. It’s especially useful in operational strategy and competitive analysis. For instance, a consumer electronics company might find that while their assembly process is highly efficient, delays in inbound logistics are causing costly bottlenecks. By dissecting each link in the chain, firms can streamline operations, strengthen competitive advantage, or decide what to outsource.
Problem Solving
Hypothesis-Based Problem Solving (HBPS)
HBPS is a structured approach used by consultants and analysts to tackle complex problems by breaking them down into falsifiable hypotheses. Rather than boiling the ocean, it guides you to focus only on the issues that matter most. For example, if a retailer is experiencing falling sales, HBPS would prompt the team to prioritise analysis by testing plausible hypotheses: Are prices too high? Is customer foot traffic down? Are online reviews affecting trust? This method is efficient, logical, and highly effective in environments of uncertainty.
MECE—Mutually Exclusive, Collectively Exhaustive—is a logic-based organising principle that ensures you don’t miss anything or double-count when breaking down a problem. It’s a cornerstone of consulting case structure. Suppose you’re segmenting a customer base: a MECE grouping might separate by age group (18–25, 26–35, etc.), which is mutually exclusive, and cover the entire population, making it collectively exhaustive. Using MECE ensures clarity, precision, and no overlaps—ideal for building issue trees, structuring recommendations, or preparing polished slides.
Marketing
The 4 P’s—Product, Price, Place, and Promotion—form the classic marketing mix, offering a holistic view of how to position and sell a product. For instance, a startup launching a new plant-based protein drink might use the 4 P’s to assess: Product (taste, health benefits), Price (premium vs mass-market), Place (supermarkets, gyms, online), and Promotion (Instagram ads, fitness influencers, in-store sampling). The 4 P’s ensure that marketing strategy touches every point where a brand meets its market.
A Customer Journey Map visualises every step a customer takes when interacting with your brand, from first discovery to purchase and beyond. It highlights moments of delight and friction, allowing businesses to improve experience at critical touchpoints. For example, a SaaS firm might map out how users discover their tool, sign up for a trial, engage with onboarding emails, and ultimately convert, or churn. Journey maps help align teams around the customer experience and are often the first step in service design or UX revamps.
The Product Life Cycle Model tracks a product’s journey through four stages: Introduction, Growth, Maturity, and Decline. Each phase requires different strategies. In the Introduction phase, firms invest heavily in marketing and education. In the Growth phase, the focus shifts to scaling and differentiation. Maturity requires a focus on efficiency and brand loyalty, while Decline might call for a product refresh or withdrawal from the market. For instance, a smartphone brand might see its flagship model transition from rapid sales growth to maturity within 18 months, prompting promotional bundling and R&D to develop the next version. Managers and consultants can use the model to sharpen timing and resource allocation.
A Product Roadmap is a strategic document that outlines the vision, direction, and major milestones for a product over time. It aligns teams across engineering, design, and marketing by showing what features are coming, when, and why. For example, a B2B SaaS platform might use its roadmap to communicate quarterly objectives: Q1 might include improved analytics; Q2, a mobile version. Internally, it sets expectations and focus; externally, it signals credibility and progress to clients or investors. A good roadmap balances ambition with realism and ties every initiative to customer value.
Startups
The Map of Life is a narrative strategy framework designed to help professionals and founders tell a compelling story about their product, project, or career. It centres on four key elements: Why (your purpose), For Whom (your target audience), Who (your unique capability or positioning), and What (the product or offering). For example, a social enterprise founder might explain: “We believe students need real-world exposure (Why), we serve disadvantaged high schoolers (For Whom), we’re ex-teachers with tech experience (Who), and we’ve built a mentorship platform that connects them to university students (What).” The framework helps to build clarity and coherence into messaging, internally and externally.
Strategy
The Ansoff Matrix helps businesses think through growth strategy by mapping four pathways: Market Penetration (selling more to existing customers), Market Development (reaching new customer segments), Product Development (creating new products), and Diversification (launching new products in new markets). For instance, a chocolate brand might pursue Market Development by entering the Japanese market, or Product Development by launching a vegan range. The matrix brings clarity to the question: Where should we grow next?
The BCG Matrix helps portfolio managers allocate resources by classifying business units into four quadrants based on market growth and market share: Stars (high growth, high share), Cash Cows (low growth, high share), Question Marks (high growth, low share), and Dogs (low growth, low share). A conglomerate like Procter & Gamble might use the matrix to identify which brands to invest in, milk, divest, or reinvent. The matrix can give a clear snapshot for managing a diversified portfolio with discipline.
The GE-McKinsey 9-Box Matrix extends the BCG approach by evaluating business units across two axes: Industry Attractiveness and Competitive Strength, each with three levels (High, Medium, Low), creating nine possible strategic positions. For example, a multinational might map its various subsidiaries and find that its logistics unit scores high in both areas, suggesting it’s a prime candidate for investment and expansion, while a media division with low scores might be shutdown or sold. It’s particularly helpful for companies with complex, multi-industry portfolios looking for structured strategic planning.
The Market Study Framework is used to assess a new or existing market through four key layers: Economy, Industry, Company, and Project. It helps consultants and investors understand external forces and internal readiness before recommending a go/no-go decision. For example, a private equity firm considering an investment in renewable energy might analyse macroeconomic trends (Economy), market competition (Industry), the target firm’s operations (Company), and the deal structure (Project). The framework ensures a thorough top-down investigation.
The Outsourcing Matrix helps firms decide which activities to keep in-house versus outsource, based on Strategic Importance and Operational Performance. For example, a car manufacturer may find that its IT infrastructure isn’t strategically core and its performance is poor—making it a strong candidate for outsourcing. Conversely, it might retain control of engine design because it’s central to brand identity and technical excellence. This matrix supports smart resource allocation and risk management in complex operations.
PEST Analysis examines the Political, Economic, Social, and Technological forces shaping an industry or market. It’s typically used in strategy development, market entry assessments, or risk scans. For example, a renewable energy startup expanding into Southeast Asia might consider government subsidies (Political), currency volatility (Economic), consumer environmental attitudes (Social), and battery storage innovation (Technological). PEST doesn’t provide answers, but it ensures no external factor is overlooked when building strategy or pitching to investors.
Porter’s Five Forces is a powerful industry analysis framework that evaluates competitive intensity based on five factors: Supplier Power, Buyer Power, Competitive Rivalry, Threat of Substitutes, and Threat of New Entrants. For instance, a new online grocer might assess that there is intense rivalry (many competitors), high buyer power (consumers can switch easily), and moderate supplier power (a small number of delivery services). If all five forces are strong, profit margins are likely to be thin. Porter’s model helps firms understand where power lies in the industry, and whether to enter, invest, defend, or exit.
Porter’s Generic Strategies describe three primary ways firms can gain competitive advantage: Cost Leadership (being the low-cost provider), Differentiation (offering something unique), and Focus (targeting a niche with one of the first two approaches). For example, Aldi uses Cost Leadership by streamlining operations, Apple employs Differentiation through appealing design and a tightly controlled ecosystem, and a boutique legal firm might use Focus to serve only tech startups. The framework reminds firms to choose a clear path or risk being “stuck in the middle.”
Porter’s Six Steps of Strategic Positioning
Porter’s Six Steps of Strategic Positioning outline how to build a sustainable strategy by focusing on activity alignment and unique value delivery. The steps include identifying the right customer, defining the value proposition, and arranging activities to reinforce one another. For example, IKEA’s self-service warehouse, flat-pack design, and limited customer service all reinforce its low-cost home furnishing strategy. The power of this framework is not in choosing what to do, but in designing a system that coherently delivers it.
SWOT Analysis is a foundational strategy tool that helps firms identify Strengths, Weaknesses, Opportunities, and Threats. It’s used in everything from strategic planning to investor pitches. A local café, for instance, might list its community loyalty as a Strength, reliance on foot traffic as a Weakness, delivery services as an Opportunity, and a new franchise competitor as a Threat. SWOT is deceptively simple, but forces holistic reflection across internal capabilities and external conditions.
The Three C’s—Customer, Company, and Competition—are the cornerstone of market analysis. It asks: What do our customers need? What can we offer? How does that compare to rivals? For example, a car brand planning an EV launch might explore rising environmental awareness (Customer), its own battery tech and design strengths (Company), and Tesla’s first-mover advantage (Competition). The Three C’s frame strategic positioning as the intersection of market need, capability, and differentiation.
The Value Net Framework extends Porter’s Five Forces by adding a crucial sixth actor: Complementors—firms whose offerings increase the value of your own. For example, consider the relationship between iPhones and app developers. More apps make iPhones more valuable, and vice versa. The framework repositions strategy from pure competition to co-opetition, recognising that value is often created with others, not just in spite of them. It’s a nuanced tool for navigating modern, interconnected markets.
