Bromwich & Bhimani wrote a interesting short book in 2010 called “Management Accounting – retrospect and prospect” (see cimapublishing.com). In the book, they give a number of examples from modern business that makes us think about management accounting techniques. For example, what exactly does a company like Facebook or LinkedIn actually do? Do they offer products, services or what? Changing technologies, business markets and new ways of making/delivering products often causes changes to management accounting. For example recently I read that amazon.com now sells more e-books than paper books. Taking this e-book example, it is easy to visualise a shift in product costs. Arguably, an e-book has almost no variable costs. Instead the vast majority of costs are probably fixed – costs of running a data centre for example. This new way of doing business changes the information management accountants need and how that same information is collated and analysed. I have no idea what publishers or distributors like amazon.com do in their management accounting functions, but it is not too hard to think about how basic techniques like breakeven (CVP) analysis would change due to the changing cost structure.
