Explain swot analysis uses in strategies analysis?

Answer 1

Very simple:

SWOT = Strength, Weakness, Opportunity, Threat

FIRST:

List your Strength

List your Weakness

List the Opportunity you see in the market

List the Threat you see in the market

SECOND:

Answer the following question, in any fashion.

(1) Is your STRENGTH good enough to overcome the THREAT you see and/or capitalize the OPPORTUNITY you see>

(2) Is your WEAKNESS bad enough to have you die from the THREAT or miss an OPPORTUNITY?

(3) To tackle the new OPPORTUNITY, what other STRENGTH/WEAKNESS had to be added or eliminated

(4) To mitigate the risk of the new THREAT, what STRENGTH/WEAKNESS had to be added or eliminated

Never forget the second step. Most people tends to only do the first, whereas it is actually the second one that's matter in a SWOT analysis.
