The learning curve – real life application
I have previously written about the learning curve and its use in management accounting practice. The learning curve effect refers to a possible tendency for tasks to be performed quicker as employees learn them and become more efficient. Thus, over time, costs may decrease. The term experience curve is also used to describe this effect – have a look at the previous post for detail on how to calculate the learning curve effect.
In October 2012, CIMA reported some research on two cases of actual use of the learning curve. The full details can be found here , but I will summarise them briefly here. Pricing was a key issue for one case, so they used the learning curve in their cost and pricing calculations to ensure they were giving customers the most competitive price. In the second case, the learning curve effect was used in investment evaluation to obtain the best future cash flow projections.

A book on which I am a co-author will be available from January 15th next. It’s a contemporary book, with an emphasis on the changing nature of management accounting. Of course we cover the basic and traditional material too. You can find out more at this link.
A new (old) way of financing – trade finance

When I was in secondary school, I took a subject called Business Organisations (or biz org as we called it). It was a bit of law, general business and finance all rolled into one. At that time a lot of it did not make sense, but when I started to work I encountered many of the things I had learned about – shareholders, annual general meeting, debt financing and so on.
I recently read an article in CIMA’s Financial Management (Sept 2012, pp. 32-34) on a topic which I have never encountered in my working life in Ireland/UK – trade finance. I do remember learning about it biz org though – not bad after 25 years almost. So what is trade finance? It is simply using the materials/supplies as a security for finance. It works as follows.
- a company needs to buy materials to complete a sales order, but does not have the free cash to pay.
- a trade finance company (or bank) agrees to buy the goods, and issues a letter of credit to guarantee the payment to the supplier.
- The customers order (often from a large well-known business) is security for the trade finance provider.
According to the article, trade finance is becoming more popular as many firms are finding it difficult to obtain or maintain a bank overdraft. You can read the full article here
A brief (but incomplete) overview of current attempts to account for sustainability : guest post 2 by Dr Stephen Jollands

Guest post #2 by Dr Stephen Jollands
In the previous post I defined sustainability as humanity not over-consuming the resources available to them and thereby irreversibly depleting the levels of natural capital while at the same time ensuring an equitable and fair distribution, both within the current generation as well as across all future generations, of the resources available. The aim of this post is to review some of the tools that claim to account for sustainability and question how well they stack up against this definition.
The obvious place to start is with the very tool we utilised to help explain sustainability, the ecological footprint. This calculates the biologically productive surface area required to sustain the thing of interest; whether that is the Earth, a specific country, an organisation, or even a specific project. Thus this tool is a very effective indicator of resource throughput. Despite being a very effective tool and adhering to a strong conception of sustainability it also has inherent weaknesses. Primarily amongst these is that it gives no indication over the health of the specific part of the ecosphere that the resources are being drawn from or the waste assimilated to. Therefore, it would appear that its effectiveness would be improved if set within a system of supporting sustainability focused management controls. We shall now turn to examining a few of these potential candidates.
The most obvious to examine next is the various types of external reporting that organisations do under the label of sustainability. There have been many differing frameworks developed in this respect including The Prince’s Accounting for Sustainability Project, the GRI and Integrated Reporting. These provide useful tools for businesses to organise their communications with their shareholders in regards to their social and environmental impacts. But this is also the source of critique for them as well. That is we have to question how far beyond public relations these reports go. The proponents of the various framework argue that the use of their frameworks provide stakeholders with an in depth analysis of the social and environmental impacts of an organisation. However, we need to question whether any rationale executive would allow the more controversial elements of their operations to be released in a public environment. When we reflect on the various accounting standards inability to provide clarity over economic affairs, as is evidenced by continual scandals, it is hardly surprising that these frameworks will probably fare no better. Further, none of these frameworks requires the organisation to report on the scale or scope of resources drawn from the ecosphere or waste assimilated back into it (i.e. an ecological footprint), which, as was explained last week, is at the heart of the issue of sustainability. This is not surprising as the accounting entity convention sets precise limits as to what is accounted for. For this very reason many commentators have expressed the view that the focus of the going concern concept should be elements of the ecosphere; such as rivers and forests; rather than the economic entity. If this was the case then economic organisations would be required to account for how they have helped maintained these ecosphere going concerns and in doing so been allowed to generate a profit.
The final example, although there is so many others we could review, which I will cover will be attempts to provide a cost to the social and environmental impacts of an organisation. The reason for selecting this as the final example is that Puma generated a large amount of publicity recently through publishing their first Environmental Profit and Loss account. Puma reports that their environmental impact for the key areas of greenhouse gas emissions, water use, land use, air pollution and waste, generated through their operations and supply chain is valued at €145 million in 2010. In the same year Puma reported that their Net Earnings were €202.2 million. This raises the question as to whether, given their Net Earnings were greater than their environmental impacts, they are therefore a truly sustainable organisation? The possibility of one of the world’s most notable examples of a consumerism driven, profit increasing through growth in sales organisations being sustainable seems to fly in the face of the evidence provided by the ecological footprint of our current over consumption of natural capital. This contradiction could be better explored had Puma provided more in depth details surrounding their calculations. However, given the involvement of consultants in this calculation, these details are unlikely to be ever released. The final question to ask is what concrete actions will this calculation result in?
In closing this quick overview, I would also question why Puma chose to put itself in a position for stakeholders to believe that it was the first organisation to provide an environmental profit and loss account when so many other notable and more transparent examples and experiments have occurred before? Or indeed we could question why Puma did not utilise one of these other tools given they are existing technologies and these tools have a close relationship with strong conceptions of sustainability? One notable example is full cost accounting (FCA). FCA as a concept integrates all potential costs and benefits, including those that relate to social and environmental, that organisations would normally consider as externalities, into the economic calculations they perform. The aim, therefore, is to ensure that a full set of broad considerations are taken into account during the decision making process. Of course here the emphasis is on decision making rather than releasing information publically and hence when this tool is used it generally does not make levels of publicity anywhere near those generated by Puma. Related to this is the sustainability assessment model (SAM), which is a tool developed in order to assist with the implementation of FCA. It is interesting that a colleague of mine focused his PhD research on assisting two local government bodies in implementing the use of SAM. While one of these were genuinely amazed at the extent of their impact and proceeded to take action accordingly, the other asked my colleague to leave when the SAM failed to deliver the “right” answer. That is when it provided visibility over the high levels of un-sustainability this plainly was unsettling to the managers involved. It is often understood by researchers in the area of accounting for sustainability that if the results do not make you feel incredibly uncomfortable you’re plainly not doing it right. Thus it is with interest that I introduce the last tool, the sustainable cost calculation (SCC). SCC is a way to measures how much it would cost an organisation to ensure that its operations left Earth at least no worse off at the end of the accounting period. The idea here is precisely to utilise the language of accounting to provide visibility over the true impacts of an organisation on natural capital and thereby the gapping chasm between our current operations and those that would be sustainable. It is interesting that the experiments with this tool have, beyond showing the un-sustainability of the organisations involved, highlighted how difficult it is to perform these calculations given the complexities and our relative dearth of knowledge as to how our ecosphere works.
The point I am trying to highlight in this post is that it is hard to be anything but cynical of many of the current attempts to account for sustainability as they do not link to the underlying issues and appear to be nothing more than attempts to generate publicity for the organisations involved.
These issues, covered in these two posts, around accounting and sustainability is the focus of my research and teaching efforts:

I would therefore encourage anyone interested in furthering their knowledge in the area of sustainability and business to consider undertaking the innovative One Planet MBA, which I teach the accounting module in:
Understanding sustainability through an accounting lens – guest post 1 by Dr Stephen Jollands
Guest post #1 by Dr Stephen Jollands
It is very interesting that Martin’s story of the wasted portions of condiments on an airline flight is a very simple setting to think through the complexities of the issues we face around sustainability. But before we examine Martin’s example further we first need to think about what exactly sustainability is and more importantly what it is not. The first question to ask is what is it that we are trying to sustain? While this may appear as quite a straight forward question the answer is not as most expect. Sustainability is about sustaining humanity. Put simply we need the ecosphere in which we live but it does not need us. This leads to an interesting understanding of a nested system view of the world. That is the economy resides in our societies and our societies in turn reside within the ecosphere. Thus no ecosphere then no society and in turn no society then no economy.
With having worked out what it is that we are trying to sustain we still need to investigate a few more things before we can put forward a concrete definition. In order to do so I need to introduce the ecological footprint, which is an accounting tool that measures the biologically productive area required to sustain a given population. This has been calculated for the entire world with the formula being the total biologically productive surface area divided by the population of the world. The result of this calculation gives us what is referred to as each individual persons Earth share. That is it provides us an indication of the average amount of biologically productive surface that we each have available to us to provide all that we need and want as well as absorb all the waste we generate. Based on 1996 data we know that the Earth share per person was roughly the size of one football field and this is not even taking into account the space required for other species we share our planet with.
To draw an appropriate conclusion from the above calculation of the average Earth share we need to draw an analogy between the ecosphere and a business. With a business we invest capital from which we expect to earn some form of interest. It is this interest that we expect to use to pay for the things we need and want to live from. However, in some situations we understand that the interest we earn may not be enough to support what we want and therefore we may decide to withdraw some of the capital. This is fine as long as we understand that we are doing this (and hence the need for good accounting) and that we understand that if we keep removing capital then the business will eventually go bankrupt. So it is with the ecosphere. Interestingly environmentalism first started to gain traction with space exploration back in the 1960s when it became very clear from the photos taken from space that we live on a finite planet. Hence we can view the ecosphere as having a finite amount of natural capital from which we derive natural interest (usually through interactions with the energy produced by the sun). So in terms of our Earth share this requires deriving everything we need from the football field without depleting the existing resources on that football field. However, the ecological footprint calculation based on 1996 data showed that our resource throughput (measuring resources being taken from the ecosphere as well as waste that the ecosphere is required to re-assimilate) was 20% over the levels of natural interest. This has increased to 50% over the levels of natural interest based on 2008 data. Put simply it would take one and a half years to generate the resources we consume within a year and thus we are currently, and potentially irreversibly, depleting the levels of natural capital, the very thing we require to keep sustaining us.
We can therefore define sustainability as humanity not over-consuming the resources available to them and thereby irreversibly depleting the levels of natural capital while at the same time ensuring an equitable and fair distribution, both within the current generation as well as across all future generations, of the resources available. Hence returning to Martin’s analogy it is not only the amount of things we waste that we must be aware of but also the levels of resources we utilise. Hence, what would the ecological footprint of Martin’s flight look like or in other words what was the amount of biologically productive surface area required to sustain this flight?
In the next post (as Martin has been kind enough to allow me to post two) I will briefly overview experiments around accounting for sustainability. As part of this we will investigate how well the measure up against accounting for a world of finite resources. We will even see that successful examples like the ecological footprint have inherent weaknesses that require us to question whether business that are serious about engaging with these issues may actually require a series of sustainability focused controls to guide their efforts.
Finally in closing, the large part of what I have written above is based on one easy to read book that I would suggest is the perfect place to start for anyone wishing to learn more about these issues:
