Format should look like below:
Goals & Objectives (Aim)
Identify your Strengths & Weaknesses
Identify your Opportunities & Threats
Discuss your strategy (Focus on pushing your strengths against your competitors or reducing risk of weaknesses against competitors.)
For example: if competitors have better brands than you, perhaps you will need to have a viral marketing campaign.
The key to making this a successful piece of writing is to have clear strengths, weaknesses, opportunities, and threats and address these by changing aspects of your business model canvas to best achieve your aim.(Do Not just list out SWOT and Canvas in a linear fashion).
