How DevOps oils the Value Chain

DevOps ? a clipped compound of development and operations – is a way of working whereby software developers are in a team with project beneficiaries. A client centred approach extends the project plan to include the life cycle of the product or service, for which the software is developed.

We can then no longer speak of a software project for say Joe?s Accounting App. The software has no intrinsic value of its own. It follows that the software engineers are building an accounting app product. This is a small, crucially important distinction, because they are no longer in a silo with different business interests.

To take the analogy further, the developers are no longer contractors possibly trying to stretch out the process. They are members of Joe?s accounting company, and they are just as keen to get to market fast as Joe is to start earning income. DevOps uses this synergy to achieve the overarching business goal.

A Brief Introduction to OpsDev

You can skip this section if you already read this article. If not then you need to know that DevOps is a culture, not a working method. The three ?members? are the software developers, the beneficiaries, and a quality control mechanism. The developers break their task into smaller chunks instead of releasing the code to quality control as a single batch. As a result, the review process happens contiguously along these simplified lines.

This is a marked improvement over the previously cumbersome method below.

Write the Code ? Test the Code ? Use the Code
? Evaluate, Schedule for Next Review ?

Working quickly and releasing smaller amounts of code means the OpsDev team learns quickly from mistakes, and should come to product release ahead of any competitor using the older, more linear method. The shared method of working releases huge resources in terms of user experience and in-line QC practices. Instead of being in a silo working on its own, development finds it has a richer brief and more support from being ?on the same side of the organisation?.

The Key Role that Application Program Interfaces Play

Application Program Interfaces, or API?s for short, are building blocks for software applications. Using proprietary software-bridges speeds this process up. A good example would be the PayPal applications that we find on so many websites today. API?s are not just for commercial sites, and they can reduce costs and improve efficiency considerably.

The following diagram courtesy of TIBCO illustrates how second-party applications integrate with PayPal architecture via an API fa?ade.

The DevOps Revolution Continues ?

We close with some important insights from an interview with Jim Stoneham. He was general manager of the Yahoo Communities business unit, at the time Flickr became a part. ?Flickr was a codebase,? Jim recalls, ?that evolved to operate at high scale over 7 years – and continuing to scale while adding and refining features was no small challenge. During this transition, it was a huge advantage that there was such an integrated dev and ops team?

The ?maturity model? as engineers refer to DevOps status currently, enables developers to learn faster, and deploy upgrades ahead of their competitors. This means the client reaches and exceeds break-even sooner. DevOps lubricates the value chain so companies add value to a product faster. One reason it worked so well with Flickr, was the immense trust between Dev and Ops, and that is a lesson we should learn.

?We transformed from a team of employees to a team of owners. When you move at that speed, and are looking at the numbers and the results daily, your investment level radically changes. This just can’t happen in teams that release quarterly, and it’s difficult even with monthly cycles.? (Jim Stoneham)

How to Reduce Costs when Complying with SOX 404

Section 404 contains the most onerous and most costly requirements you’ll ever encounter in the Sarbanes-Oxley Act (SOX). In this article, we?ll take a closer look at the salient points of this contentious piece of legislation as it relates to IT. We?ll also explain why companies are encountering difficulties in complying with it.

Then as soon as we’ve tackled the main issues of this section and identify the pitfalls of compliance, we can then proceed with a discussion of what successful CIOs have done to eliminate those difficulties and consequently bring down their organisation’s IT compliance costs. From this post, you can glean insights that can help you plan a cost-effective way of achieving IT compliance with SOX.

SOX 404 in a nutshell

Section 404 of the Sarbanes-Oxley Act, entitled Management Assessment of Internal Controls, requires public companies covered by the Act to submit an annual report featuring an assessment of their company?s internal controls.

This ?internal control report? should state management’s responsibility in establishing/maintaining an adequate structure and a set of procedures for internal control over your company?s financial reporting processes. It should also contain an assessment of the effectiveness of those controls as of the end of your most recent fiscal year.

Because SOX also requires the public accounting firm that conducts your audit reports to attest to and report on your assessments, you can’t just make baseless claims regarding the effectiveness of your internal controls. As a matter of fact, you are mandated by both SEC and PCAOB to follow widely accepted control frameworks like COSO and COBIT. This framework will serve as a uniform guide for the internal controls you set up, the assessments you arrive at, and the attestation your external auditor reports on.

Why compliance of Section 404 is costly

Regardless which of the widely acceptable control frameworks you end up using, you will always be asked to document and test your controls. These activities can consume a considerable amount of man-hours and bring about additional expenses. Even the mere act of studying the control framework and figuring out how to align your current practices with it can be very tricky and can consume precious time; time that can be used for more productive endeavours.

Of course, there are exceptions. An organisation with highly centralised operations can experience relative ease and low costs while implementing SOX 404. But if your organisation follows a largely decentralised operation model, e.g. if you still make extensive use of spreadsheets in all your offices, then you’ll surely encounter many obstacles.

According to one survey conducted by FEI (Financial Executives International), an organisation that carried out a series of SOX-compliance-related surveys since the first year of SOX adoption, respondents with centralised operations enjoyed lower costs of compliance compared to those with decentralised operations. For example, in 2007, those with decentralised operations spent 30.1 % more for compliance than those with centralised operations.

The main reason for this disparity lies in the disorganised and complicated nature of spreadsheet systems.

Read why spreadsheets post a burden when complying with SOX and other regulations.

Unfortunately, a large number of companies still rely heavily on spreadsheets. Even those with expensive BI (Business Intelligence) systems still use spreadsheets as an ad-hoc tool for data processing and reporting.

Because compliance with Section 404 involves a significant amount of fixed costs, smaller companies tend to feel the impact more. This has been highlighted in the ?Final Report of the Advisory Committee on Smaller Public Companies? published on April 23, 2006. In that report, which can be downloaded from the official website of the US Securities and Exchange Commission, it was shown that:

  • Companies with over $5 Billion revenues spent only about 0.06% of revenues on Section 404 implementation
  • Companies with revenues between $1B – $4.9B spent about 0.16%
  • Companies with revenues between $500M – $999M spent about 0.27%
  • Companies with revenues between $100M – $499M spent about 0.53%
  • Companies with revenues less than $100M spent a whopping 2.55% on Section 404

Therefore, not only can you discern a relationship between the size of a company and the amount that the company ends up spending for SOX 404 relative to its revenues, but you can also clearly see that the unfavourable impact of Section 404 spending is considerably more pronounced in the smallest companies. Hence, the smaller the company is, the more crucial it is for that company to find ways that can bring down the costs of Section 404 implementation.

How to alleviate costs of section 404

If you recall the FEI survey mentioned earlier, it was shown that organisations with decentralised operations usually ended up spending more for SOX 404 implementation than those that had a more centralized model. Then in the ?Final Report of the Advisory Committee on Smaller Public Companies?, it was also shown that public companies with the smallest revenues suffered a similar fate.

Can we draw a line connecting those two? Does it simply mean that large spending on SOX affects two sets of companies, i.e., those that have decentralised operations and those that are small? Or can there be an even deeper implication? Might it not be possible that these two sets are actually one and the same?

From our experience, small companies are less inclined to spend on server based solutions compared to the big ones. As a result, it is within this group of small companies where you can find a proliferation of spreadsheet systems. In other words, small companies are more likely to follow a decentralised model. Spreadsheets were not designed to implement strict control features, so if you want to apply a control framework on a spreadsheet-based system, it won’t be easy.

For example, how are you going to conduct testing on every single spreadsheet cell that plays a role in financial reporting when the spreadsheets involved in the financial reporting process are distributed across different workstations in different offices in an organisation with a countrywide operation?

It’s really not a trivial problem.

Based on the FEI survey however, the big companies have already found a solution – employing a server-based system.

Typical server based systems, which of course espouse a centralised model, already come with built-in controls. If you need to modify or add more controls, then you can do so with relative ease because practically everything you need to do can be carried out in just one place.

For instance, if you need to implement high availability or perform backups, you can easily apply redundancy in a cost-effective way – e.g. through virtualisation – if you already have a server-based system. Aside from cost-savings in SOX 404 implementation, server-based systems also offer a host of other benefits. Click that link to learn more.

What Kanban can do for Call Centre Response Times

When a Toyota industrial engineer named Taiichi Ohno was investigating ways to optimise production material stocks in 1953, it struck him that supermarkets already had the key. Their customers purchased food and groceries on a just-in-time basis, because they trusted continuity of supply. This enabled stores to predict demand, and ensure their suppliers kept the shelves full.

The Kanban system that Taiichi Ohno implemented included a labelling system. His Kanban tickets recorded details of the factory order, the delivery destination, and the process intended for the materials. Since then, Ohno?s system has helped in many other applications, especially where customer demand may be unpredictable.

Optimising Workflow in Call Centres
Optimising workflow in call centres involves aiming to have an agent pick up an incoming call within a few rings and deal with it effectively. Were this to be the case we would truly have a just-in-time business, in which operators arrived and left their stations according to customer demand. For this to be possible, we would need to standardise performance across the call centre team. Moving optimistically in that direction we would should do these three things:

  • Make our call centre operation nimble
  • Reduce the average time to handle calls
  • Decide an average time to answer callers

When we have done that, we are in a position to apply these norms to fluctuating call frequencies, and introduce ?kanbanned? call centre operators.

Making Call Centre Operations Nimble
The best place to start is to ask the operators and support staff what they think. Back in the 1960?s Robert Townsend of Avis Cars famously said, ?ask the people ? they know where the wheels are squeaking? and that is as true as ever.

  1. Begin by asking technical support about downtime frequencies, duration, and causes. Given the cost of labour and frustrated callers, we should have the fastest and most reliable telecoms and computer equipment we can find.
  1. Then invest in training and retraining operators, and making sure the pop-up screens are valuable, valid, and useful. They cannot do their job without this information, and it must be at least as tech-savvy as their average callers are.
  1. Finally, spruce up the call centre with more than a lick of paint to awaken a sense of enthusiasm and pride. Find time for occasional team builds and fun during breaks. Tele-operators have a difficult job. Make theirs fun!

Reducing Average Time to Handle Calls
Average length of contact is probably our most important metric. We should beware of shortening this at the cost of quality of interaction. To calculate it, use this formula:

Total Work Time + Total Hold Time + Total Post Call Time

Divided By

Total Calls Handled in that Period

Share recordings of great calls that highlight how your best operators work. Encourage role-play during training sessions so people learn by doing. Publish your average call-handling time statistics. Encourage individual operators to track how they are doing against these numbers. Make sure your customer information is up to date. While they must confirm core data, limit this so your operators can get down to their job sooner.

Decide a Target Time to Answer Calls
You should know what is possible in a matter of a few weeks. Do not attempt to go too tight on this one. It is better to build in say 10% slack that you can always trim in future. Once you have decided this, you can implement your Kanban system.

Introducing Kanban in Your Call Centre Operation
Monitor your rate of incoming calls through your contact centre, and adjust your operator-demand metric on an ongoing basis. Use this to calculate your over / under demand factor. Every operator should know the value on this Kanban ticket. It will tell them whether to speed up a little, or slow down a bit so they deliver the effort the call rate demands. It will also advise the supervisor when to call up reserves.

Solutions to Password Overload

If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.

So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.

Why keeping passwords in memory is no longer possible

A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.

For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.

Remembering that one alone can be pretty daunting.

To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.

The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.

Password management solutions

Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.

Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.

But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.

Web-based password manager

A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.

If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.

With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.

Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
