In the following chapters, you will learn about the core, fundamental tools your business should have from various anchors such as the business idea, marketing, and financial domains. You need to develop your robustness in these areas as you take your entrepreneurial journey.In my case, I have learned these academically and then applied them in the real-world setting. I also discuss them with my clients during sessions of coaching, mentoring, advising to take their business to the next level.During client sessions, I begin with defining each area while my clients do their research. I used most of the techniques in this guide to value the progress of their businesses. Thereafter, it became easier for me to provide them with the best strategy or business advice for going into the next level in forms of increasing efficiency, overcoming weaknesses, and spotting new market opportunities.
