Rapid Review Of Instant MBA 1-5 here.
Instant MBA 6 (here). Forget time, focus on decisions. And these are typically investment ones; ones in which you are working ON your business. Improving skills, reflecting on strategy and building future business pipelines.
Instant MBA 7: Differentiation. Get big, get niche or get out. Your business must be different otherwise it will resort to the only 'difference' it has: lower and lower prices which is clearly a slippery slope to disaster. Organise a classic SWOT (strengths/weaknesses/opportunities and threats) analysis. Discover, re-discover and create difference.
