You can find a variety of companies online to help you with your market research. For example: Sundale Research's (sundaleresearch.com) primary goal is to provide new and mature businesses with objective, accurate industry data and market analysis on a wide range of topics. Their market research is intended to save you time and money while keeping up with industry trends. But your idea may be so new that you may also need to talk to potential customers, host some focus groups, talk to an ad agency, or maybe even make a prototype and float it past some people. Be prepared to spend the time. Remember, it's not about the Plan but the Planning.
What are the critical steps needed to achieve a successful business plan? This may come as a surprise to my fellow business consultants, but producing a successful business plan is not as difficult as people often think, so long as they follow a logical sequence. Here is my considered view as to the critical steps. 1. Understand what you are planning and why; 2. Define the activities of your organisation; 3. Outline the current position of the business; 4. Review and discuss the external market conditions, undertake and understand a competitive analysis, and define your market positioning; 5. Define your core objectives; 6. Prepare and articulate the strategy to attain and meet the objectives; 7. Identify and review risks and opportunities; 8. Prepare a strategy to deal with risks and exploit opportunities; 9. Refine the strategies into operational plans; 10. Prepare financial forecasts including revenues, costs, cash_flow, capital expenditure and assumptions adopted; 11. Finalise the plan; 12. Get it approved; 13. Use it; 14. Review it regularly and update as appropriate.
