Management accountants and technology change

Changes in technology is regularly a top issue for management accountants when asked. Of course in recent years, the pace of technology change has been so rapid compared to previous. How can management accountants deal with such change? An article from the CGMA provides some useful tips.

What is big data?

This post gives you a brief introduction to “big data”, a term used in many circles and in many businesses. The following posts will then give some examples from real business to help you understand the effects this might have on accounting and accountants.


Although the term big data has become mainstream in recent years, it has been used for a decade or more by scientists to simply describe very large amounts of data. Diebold (2003)  defines big data as follows:


Big data refers to the explosion of quantity (and sometimes, quality) of available and potentially relevant data, largely the result of recent and unprecedented advances in data recording and storage technology.


It is hard to believe that this definition although only a decade or so old, bears little resemblance to what can be achieved today in terms of data collection. Devices such as smartphones and tablets in a cloud-computing environment allow users to use cloud-based services (such as software or social networks) and, in turn, data can be collected through these devices and stored elsewhere in the cloud. The result is vast potentially vast amount of data, which can be analysed for many purposes, including business decisions. Facebook has about a billion users, there are about 500 million tweets per day sent on Twitter and Google handles about 3 billion search queries per day. These vast uses of each of the mentioned websites/network generates hitherto unknown amounts of data, some of which may be useful, some of which may not. In an article for Forbes, Feinleib notes three issues with big data, which give a good insight into what it is, and the problems facing business:


1) big-data is ill-defined.. We are not sure what exactly big data is,  but a Jevons Paradox seems to exist in the world of big data. As technology evolved to allow the storage and analysis of large volumes of data, more data is being stored and analysed by organisations.


2) big data is intimidating. He asks “how do we make big data approachable” from perspectives such as having tools to analyse data, to getting the right insights and information from the data.


3) big data is immediate. Huge volumes of data are generated, but the analytical value of this data can decay rapidly. For example, in the near future companies like Google and Groupon may display adverts on mobile devices for businesses in the immediate proximity of a consumer – the time to analyse and act on this data could be a matter of minutes, or even seconds.

Technology and new business-models – taxi despatching

English: London black cab (Hackney carriage) C...

I always like to read about new ways of doing business, or new technology can change existing businesses.  You may have seen how various new technologies have helped the taxi-sector. For example, in London you can send a text from a smart phone requesting a taxi and your position can be pin-pointed by the GPS within the phone. Now let’s take this a step further and add an app to the smart phone and then the way the whole taxi industry operates could change? How you might ask.  This post from the Babbage blog on Economist.com explains why. In several European countries, taxi users can now use apps to request a taxi. The apps ping the nearest cab, and once a customer accepts a particular offer they can track the taxi progress. All the taxi needs is the same app effectively.   This changes the way business is done in the sector as the taxi dispatcher is effectively cut out of the picture. I don’t know about other cities, but I can tell you that a taxi dispatcher would charge its drivers in the order of €200 per week or more in Dublin. For this, the driver (who suffers all risks of owning and paying for the cab) gets fares directed to them usually through some system installed in their cab. Now, if I were a self-employed taxi-driver you could cut out that cost by using an app, I’d be giving it some serious consideration. Of course, as the post notes, taxi dispatchers are not seating idle and a race is on between taxi dispatchers and app developers!
