Strategic Marketing and Commercial Decision-Making
Core concepts
Strategic marketing concerns choices about where to compete and how to win. Understand Ansoff's matrix (market penetration, product development, market development, diversification) and be able to place a scenario accurately. Porter's generic strategies - cost leadership, differentiation, focus - plus the risk of being "stuck in the middle" are core. Portfolio tools such as the BCG matrix (stars, cash cows, question marks, dogs) and the product life cycle inform resource allocation; know their limitations, notably that the BCG axes are subjective and the life cycle is descriptive rather than predictive. Competitive analysis includes Porter's five forces and the idea of sustainable competitive advantage built on resources that are valuable, rare, hard to imitate and non-substitutable. Commercially, candidates should connect marketing decisions to margin, share, customer lifetime value and payback, and understand brand architecture and extension decisions.
Traps
Questions frequently mislabel Ansoff options, especially calling a new product for existing customers market development. The BCG matrix is often tested via a mislabelled cash cow. Watch for answers that recommend diversification without discussing risk, and for generic strategies where an answer claims both low cost and broad differentiation without evidence.
Worked example
A firm with strong existing distribution launches its current product into an adjacent country. This is market development, not diversification, because both product and capability are unchanged. Rule of thumb: for Ansoff, ask two questions - is the product new, and is the market new? Only "yes" to both is diversification.
