We swim in the "water" of our culture without recognising it as an important determining factor. And sociological analysis is all about analysing the background culture. Technological factors are usually easier to spot, because new technologies involve change, and change is always noticed. For instance, online shopping has had a major impact on Tesco's recent success. The change created by technological advances often lead to legal problems, which is why legal analysis is always an important part of a PESTLE analysis.
Tesco's operations obviously have a significant environmental impact, from fossil fuel use to packaging issues. Reducing the demand on the planet is a challenge for any big company. A PESTLE Analysis for Tesco must look at all the six factors we have mentioned. Here they are again, with examples of each:
political: an increase in unemployment due to a downward turn in the world economy.
economic: impact on sales of the credit crunch. sociological: an increase in immigration from Eastern Europe resulting in a demand for new goods.
technological: how can Tesco take full advantage of the world wide web
legal: how can Tesco avoid legal opposition to expanding into new high streets
environmental: climate change is affecting supply and transport, how can Tesco adapt
In summary, any PESTLE Analysis for Tesco must consider all external factors.
