Businesses, public and private, large and small, global and local, are always seeking and struggling with researching and discovering new and improved methods of improving and accelerating revenue  performance.
Ask nearly any business person; entrepreneur, manager, chief executive or frontline manager, what they most want in their business and in today's business climate and the answer you will hear most often will be that they want more customers/clients who provide them with higher, more frequent and more profitable business. And that's exactly what most of them spend the majority of their marketing time, money and effort on ... acquiring new higher value customers and clients.
The first step in virtually every company analysis project is to carefully examine what the company does to generate revenue.  Secondly, it is a good idea to develop a perspective based on historical trends. As a starting point, it is useful to compile a table of quarterly revenue over several recent years in a spreadsheet application.
The more detail the better - if a company has more than one business segment, it is helpful to break out each revenue component in the table. Once the data is in the table, you can measure year-over-year and sequential (quarter to quarter) percentage growth in revenue for each time period.
