  • Exploiting the weak points

    Exploiting the weak points

    The Great ATM Heist, where a crime gang subverted the credit card system, could well be the digital equivalent of the Great Train Robbery of the 1960s.

    While the logistics of the operation are impressive with hundreds of accomplices across twenty countries, the real moral from the story comes from how the gang targeted outsourced credit card processing companies to adjust cash limits.

    Again we see the risks of throwing your problems over the fence, a system is only as reliable or secure as the weakest link and, regardless of how tight commercial contracts are, outsourced services can’t be treated as someone else’s concern.

    No doubt banks around the world will be having a close look at their systems and how they can trust other organisations’ outsourced operations.

  • Smelling digital garbage

    Smelling digital garbage

    Excel spreadsheets lie at the core of business computing, but what happens when they go wrong?

    James Kwak writing in the Baseline Scenario blog describes how Excel spreadsheets have an important role in the banking industry and their key role in one of the industry’s most embarrassing recent scandals.

    In the early days of the personal computer spreadsheets; it was company accountants and bookkeeping clerks who bought the early PCs into offices to help them do their jobs in the late 1980s .

    From the accounts department, desktop computers spread through the businesses world and the PC industry took off.

    Over time, Microsoft Excel displaced competitors like Excel 1-2-3 and the earliest spreadsheet of all, VisiCalc, and became the industry standard.

    With the widespread adoption of Excel and millions of people creating spreadsheets to help do their jobs came a new set of unique business risks.

    The weakness with Excel isn’t with the program itself, it’s that the formulas in many spreadsheets aren’t properly tested and often incorrect data is put into the wrong fields.

    In his story Kwak cites the JP Morgan spreadsheets that miscalculated the firms Value-At-Risk (VAR) calculations for synthetic derivatives. The result was the London Whale debacle where traders were allowed to take positions – some would call them bets – exposing the bank to huge potential losses.

    It turns out that faulty spreadsheets had a key role as traders cut and paste data between various spreadsheets and the formulas that made the calculations had basic errors.

    That a bank would have such slapdash procedures is surprising but not shocking, almost every organisation has a similar setup and it gets worse as a project becomes more complex and bigger numbers become involved. The construction industry is particularly bad for this.

    Often, a spreadsheet will show out a bunch of numbers which simply aren’t correct. Someone made a mistake entering some data or one of the formulas has an error.

    The business risk lies in not picking up those errors, JP Morgan fell for this and probably every business has, thankfully to less disastrous results.

    My own personal experience was with a major construction project in Thailand. One sheet of calculations had been missed and the entire budget for lights – not a trivial amount in a 35 storey five star hotel – hadn’t been included in the contractor’s price.

    This confirmed in my mind that most competitive construction tenders are won by the contractor who made the most costly errors in calculating their price. Little has convinced me otherwise since.

    In the computer industry there’s a saying that “garbage in equals garbage out” which is true. However if the computer program itself is flawed, then good data becomes garbage.

    Excel’s real flaw is that it can make impressive looking garbage that appears credible if it isn’t checked and treated with suspicion. The responsibility lies with us to notice the smell when the computer spits out bad figures.

  • NFC and the car key revolution

    NFC and the car key revolution

    Many businesses have made easy money by ‘clipping the ticket’ of the customer, new technologies like Near Field Communications and cloud computing threaten the easy profits of many organisations.

    During yesterday’s 2UE Tech Talk Radio spot where Seamus Byrne and I stood in for Trevor Long, host John Cadogan raised the prospect of replacing car keys and even dashboards with smartphones equipped with Near Field Communications (NFC) systems.

    Since NFC technologies appeared we’ve concentrated on the banking and payments aspects of these features but there’s far more to this technology than just smartphones replacing credit cards.

    With the right software an NFC equipped smartphone, tablet computer, or even a wristwatch could replace any electronic controller – this is already happening with Wi-Fi or Bluetooth enabled home sound systems, TV remote controllers and games consoles.

    An important effect of this is that it cuts out expensive custom replacements like bespoke control units or electronic car keys.

    Car keys are a good example of how what was previously a high cost profitable item becomes commodified and those business that had a nice revenue stream find new technology cuts them out.

    As keys become replaced with NFC enabled devices then then the scam of with new sets of keys costing up to a thousand dollars with fat profits for everybody involved becomes redundant.

    This is something we’re seeing across industries as incumbent businesses find their profitable activities disrupted by smart players using new technology.

    Just as manufacturing and publishing have been dealing with these disruptions for the past two decades, it’s coming to all industries and it’s going to take smart operators to deal with the changes.

  • What would you do if the computer screen went dark?

    What would you do if the computer screen went dark?

    What would you do if the computer went dark? originally appeared in Smart Company on November 29, 2012.

    One of the truisms of business is the more ways customers can pay; the more likely you are to make the sale.

    This is particularly true when something goes wrong – the customer hasn’t any cash, the till is jammed or the EFTPOS system is down.

    Exactly this happened to thousands of businesses across south-west Victoria last week when a fire burned down the Warrnambool telephone exchange.

    Unfortunately for the people and businesses of the surrounding region, much of the telephone, internet and Telstra’s mobile network runs through the burned out telephone exchange, sending the district back into the pre-telephone days.

    This presented real problems as customers couldn’t use EFTPOS or get cash out of ATMs, while businesses struggled to get payrolls done or place orders with suppliers who couldn’t comprehend that it wasn’t possible to place orders over the net or by fax.

    A hundred kilometres north of Warrnambool in the Grampians town of Dunkeld, a cafe worker told the ABC, “suppliers say ‘send a fax’ and you’re like ‘we can’t’ and they’re like ‘oh, we don’t want to handwrite it’.”

    Those suppliers are a good example of not having the systems or staff in place to deal with ‘out of the box’ situations.

    Unexpected events like the phone network being down for a week, major floods, devastating bushfires or zombie invasions will test businesses and it’s why having a real Business Continuity Plan (BCP) is important for business.

    A workable BCP is one that identifies all the critical failure points for the business such as not having the internet for a week, a flooded office or, as happened to one of my clients, their entire building collapsing into the construction site next door.

    The various state business agencies have guides on what to consider in a Business Continuity Plan including a good one from the South Australian government.

    Regardless of how comprehensive a plan your business has, the most important part is going to be your people. If your organisation is staffed or managed by people who like to say “computer says no,” then they are going to be particularly useless when the computer is stone dead.

    As the Warrnambool outage shows, unexpected business disruptions can come from anywhere, so flexible thinking and initiative is what matters in a crisis. It’s something worth thinking about with your staff and systems.

  • Newly normal in the English Midlands

    Newly normal in the English Midlands

    On their metal, a story from BBC Radio’s In Business program looked at how the English Midlands is dealing with the toughest economic conditions the beleaguered region has suffered for decades.

    Once the centre of the industrial revolution, The Midlands have had a tough time of the last fifty years as the region caught the brunt of Britain’s de-industrialisation and the loss of thousands of engineering jobs.

    Today, the surviving engineering companies are struggling to find new markets as orders from Europe dry up and many Midlands workers find they are confronting the ‘New Normal’.

    The ‘New Normal’ for British industry is described by Mark Smith, Regional Chairman, Price Waterhouse Coopers Birmingham who points out that UK industries have to sell to the fast growing economies.

    Interestingly this is similar, but very different in practice, to the Australian belief – where the Asian Century report sees Australia continuing being a price-taking quarry for Asia rather than selling much of real value – the Brits see some virtue in adding value to what they sell to Asia’s growing economies.

    The British experience though shows the realities of the ‘New Normal’ for Western economies – the cafe owner featured in story now offers no dish over £3 and the idea of overpriced five quid tapas are long gone. The customers can’t afford it.

    Part of this is because of the casualisation of the workforce as people find salaried jobs are no longer available and become freelancers or self-employed. One could argue this is the prime reason why unemployment hasn’t soared in the UK and US since the global financial crisis.

    That ‘new normal’ features the precariat – the modern army of informal white and blue collar workers who have more in common with their grandparents who worked for day wages at the docks and factories in the 1930s than their parents who had safe, stable jobs through the 1950s and 60s.

    For the precariat, the idea of sick leave, paid holidays or a stable career started to vanish after the 1970s oil shock and accelerated in the 1990s. The new normal is the old normal for them, there just happens to be more of them after the 2008 crash.

    With a workforce increasingly working for casual wages without security of income, the 1980s consumerist business model built around ever increasing consumption starts to look damaged.

    The same too applies to the banking industry which grew fat on providing the credit that unpinned the late 20th Century consumer binge.

    When the 2008 financial crisis signalled the end of the 20th Century credit binge, the banks were caught out. Which is why governments had to step in to help the financial system rebuild its reserves.

    The effects of that reserve building also affected businesses as bank credit dried up. Early in the BBC program Stuart Fell, the Chairman of Birmingham’s Metal Assemblies Ltd described how his bank decided to cut his line of credit from £800,000 to £300,000 which forced the management to find half a million pounds in a hurry.

    That experience has been repeated across the world as banks have used their government support and easy money policies to recapitalise their damaged accounts rather than lend money to entrepreneurial customers to build businesses.

    Businesses are now looking at other sources to find capital from organisations like the Black Country Reinvestment Society which is profiled in the story that raises money from local investors to provide small businesses with working capital.

    Communities helping themselves and each other is the real ‘New Normal’ – waiting for the banks to lend money or hoping that surplus obsessed governments will save businesses or provide adequate safety will only end in disappointment as the real austerity of our era starts to be felt.

    The New Normal is declining income for most people in the Western world and we need to think of how we can help our neighbours as most of us can be sure we’re going to need their help.

    Just as the English Midlands lead the world into the industrial revolution, it may be that the region is giving us a view of what much of the Western world will be like for the next fifty years.
