Tesco's Weaknesses
To determine Tesco's Weaknesses you can use a variety of techniques including:
Of these, SWOT analysis is the most appropriate to start with—the "W" in SWOT stands for weaknesses.
One of Tesco's weaknesses has been its failure to dominate the city centre marketplace. Although it has some prominent city centres stores, e.g. the Carlisle store in the North of England, it has failed to make them universal. For instance, Milton Keynes has no city-centre Tesco store.
In the case of Milton Keynes, Sainsbury has a monopoly amongst the large supermarkets in the city centre. Tesco's failure to provide competition shows a significant weakness in its marketing approach. Given Tesco's overall market dominance, the other supermarkets can draw some relief from such signs of weakness.
