Full of actionable advice, Keys to Success is a step-by-step MBA for business women and men who need results now. From encouraging flexible working, having a happy index and a great bonus scheme to the importance of checking the cash on hand every day and planning for disaster scenarios; from why you should never make decisions at meetings to the value of a mentor - even when you're at the top - these are essential markers on your roadmap to business success, whatever business you're in.
