The infrastructure challenges for IT managers - by IT manager





By Bryan Glick



Sometimes in the IT department, nobody can hear you scream. If your day feels a little like that, then take some reassurance that you are not alone.
Yesterday I chaired a roundtable debate organized by 360°IT - the IT infrastructure event. Around the table were IT managers from various mid-sized organisations, including financial services firms, public sector bodies and charities - a real cross section of the heartland of UK IT.
The aim of the meeting was to discuss the top infrastructure challenges faced by this important sector of the IT community and for delegates to share their experiences and hopefully learn from each others' knowledge.
Perhaps the most notable outcome of the discussion was the agreement that, despite such varying environments and backgrounds around the table, the challenges they all face are remarkably similar. Everyone went away saying that, if nothing else, it was good to know they were not alone.
The debate was conducted under the Chatham House rule, so I can't identify any of the contributors, but here's a summary of their top five challenges and some of the comment they made - are these familiar issues to you? Let us know what you think by commenting at the end of this blog post.
The top five, in no particular order, were:
·         How to connect IT with the strategic priorities of the organisation
·         Communicating and marketing IT more effectively
·         Compliance, governance, metrics and risk management
·         Supplier relations
·         Technology is not the problem
How to connect IT with the strategic priorities of the organisation
One of the biggest frustrations the IT managers feel is the difficulty of aligning IT with the key priorities of their organisation - which must be one of the oldest chestnuts in technology management.
Most of the delegates had experience of a lack of joined-up thinking, and the difficulty of getting a holistic, top-down approach from the boardroom to drive IT strategy, rather than the "piecemeal" approach identified by one contributor.
One delegate highlighted the problems caused by a major outsourcing deal. To paraphrase his comments: "We outsourced because the board wanted to save money and focus on our core business. But outsourcing has removed the IT manager's ability to adequately support the business. The outsourcing deal is driven by SLAs [service-level agreements], but they don't take into consideration all the little things that IT used to do to help out before the people were outsourced. In the end, most of the cost savings have had to be spent on funding new initiatives that were not covered by the outsourcing contract, so the net result is no savings."
Another issue came from demands to minimise capital expenditure (capex) and fund IT through operating expenses (opex) instead. "We even had to put our staff party on opex," said one delegate.
Another said: "A number of major corporate projects mean there is little capex budget left for anyone. But management are loath to spend out of revenue, so IT is just expected to adapt."
And too often, budget for new initiatives goes to "whoever shouts the loudest" because of a lack of strategic direction for IT to be able to make a business case."It is about getting the right balance between tactical and strategic, and between being reactive and responsive," said one IT manager.
Communicating and marketing IT more effectively to the rest of the organisation
The other side of the lack of alignment between strategy and IT is the need for the IT department to communicate better with the rest of the organisation and the boardroom.
"IT people are not naturally good at marketing themselves," said one delegate. Another added: "We have to articulate things in a language the business understands."
Guest speaker Denise Plumpton, the non-executive director of the 360°IT event and a former CIO in both government and industry, highlighted an example from one of her former roles, where she was able to demonstrate that giving a Blackberry to sales staff allowed them to make one extra sales call per day. The sales director, who had previously been sceptical of the technology, translated that into the number of extra calls across the sales force, the likely contract conversion rates, and on the back of an envelope proved the business case for equipping his team with handheld devices - all because the case was made in a language he understood.
Another delegate warned of the danger of IT being seen as "the 'no' department" - always pointing out the reasons users cannot do something, rather than how to achieve it or the implications of doing so. "IT is seen as negative to users - they think we always say what can't be done rather than what could be done," he said.
IT departments need to treat users as individuals, and understand their needs and how to meet those requirements, said a delegate.
Compliance, governance, metrics and risk management
One way for IT to be noticed is for anything associated with regulatory compliance.
"If it's to do with compliance, it will happen," said a delegate. "Compliance can drive the rest of the business to consider IT more."
A risk management approach was highlighted as an effective way to make sure the board understands the impact of an IT business case. For example, if a business risk that could cost the company, say, one per cent of its revenue could be eliminated by better IT, that makes a compelling argument to proceed.
Agreeing metrics for measuring the value and success of IT was identified as another effective tool - especially the concept of a management dashboard of key measures - something that would also help with other challenges mentioned above, such as the relationship between IT and the organisation.
Supplier relations
One challenge that particularly animated our roundtable guests was supplier relations - with everyone highlighting problems with the key vendors they buy from. Here's a selection of comments:
"We want flexibility from our suppliers - but they all work to SLAs."
"What we bought is not what we wanted, but it was what the board thought we wanted."
"There is no partnership in the relationship with suppliers."
"We want transparency from suppliers - they need to be honest about what they can and cannot deliver."
There was complete agreement that suppliers are too focused on products and technologies, and not enough on the real challenges that IT managers face. "They are just not on the same wavelength," said one.
Another added: "The supplier has already won the business with us, yet it is always trying to sell more. "
The IT managers acknowledged that they as the customer must also take responsibility for what they want from suppliers, but many felt that suppliers were simply trying to sell "out of the box solutions".
"What we want is value added after purchase, help to make it work in our environment," said a delegate.
Technology is not the problem
In the course of nearly two hours discussion at a roundtable billed as covering IT infrastructure challenges, it was notable that technology and products were barely mentioned.
In a group of large-company CIOs, it would be expected that technology would rarely feature, but it was instructive to see that in an audience of mid-sized organisations, IT managers are also noticeably less concerned about technical issues than about business, strategy and people matters.
"Technology is not the issue, it's about skills, training, processes," said one delegate.
"I'm not interested in 'stuff'," said another. "We've got the stuff, what we want is to use it better."
A similar group assembled even five years ago would, in my experience, have spent the time discussing the relative merits of the latest technology, or the "next big thing". But products and technologies are now seen merely as the enabler, a tool that allows IT managers to contribute to the success of their organisation. That will increasingly prove to be a big step towards addressing the first two challenges highlighted above, of better aligning IT and the business, and of IT staff talking the language of the business.
It also sends out an important message to IT suppliers that their customers' expectations of them are changing rapidly.

Some of IT Management Challenges



 IT Management Challenges
Creating and managing a coherent IT infrastructure raises multiple challenges: makingwise infrastructure investments, coordinating infrastructure components, dealing withscalability and technology change, and management and governance.


  • MAKING WISE INFRASTRUCTURE INVESTMENTS
IT Infrastructure is a major capital investment for the firm. If too much is spent on infrastructure, it lies idle and constitutes a drag on firm financial performance. If too little isspent, important business services cannot be delivered and the firm’s competitors (whospent just the right amount) will outperform the underinvesting firm. How much shouldthe firm spend on infrastructure? This question is not easy to answer.A related question is whether a firm should purchase its own IT infrastructure components or rent them from external suppliers. As we discussed earlier, a major trend incomputing platforms—both hardware and software—is to outsource to externalproviders. The decision either to purchase your own IT assets or rent them from external     providers is typically called the rent versus buy decision.


  • CHOOSING AND COORDINATING INFRASTRUCTURE
COMPONENTSFirms today create IT infrastructures by choosing combinations of vendors, people, andtechnology services and fitting them together so they function as a coherent whole. Wheneach element of infrastructure is driven by somewhat different forces, accomplishing this is a major management job. For instance, changes in law may mandate vast increases indata storage and retrieval, but the existing hardware platform may be incapable of supporting the addition computing demand.


  • DEALING WITH INFRASTRUCTURE CHANGE
As firms grow, they can quickly outgrow their infrastructure. As firms shrink, they canget stuck with excessive infrastructure purchased in better times. How can a firm remainflexible when most of the investments in IT infrastructure are fixed cost purchases andlicenses? How well does the infrastructure scale? Scalability refers to the ability of acomputer, product, or system to expand to serve a larger number of users without breaking down.How can the infrastructure be changed, and over what time frame? Because the firm’sdigital infrastructure permeates every nook and cranny of the firm, and therefore directly affects how employees perform on a daily basis, any change in this infrastructurewould seem to have to occur slowly, guided by some vision (business or technologybased) or understanding of the future requirements for infrastructure. Left to constituentbusiness units, or a single chief information officer and his or her staff, chaos could reignor, alternatively, bold technologically advanced plans may come and go without any realchange. Who will supply this vision or understanding needed for long-term, stable evolution?


  • MANAGEMENT AND GOVERNANCE
A long-standing issue among information system managers and CEOs has been thequestion of who will control and manage the firm’s IT infrastructure. Should departments and divisions have the responsibility of making their own information technologydecisions or should IT infrastructure be centrally controlled and managed? What is therelationship between central information systems management and business unit information systems management? How will infrastructure costs be allocated among businessunits? Each organization will need to arrive at answers based on its own needs.

CHALLENGES, AND SOLUTIONS

The top 5 challenges for IT infrastructure management




Infrastructure management comes with its own unique challenges whether you are managing a lab network, computer farm, load-balancing application, or a build-and-release system .  As much as people lump things into the term “information technology,” every piece of “it” is its own unique world, and it’s easy to miss the differences or even divisions between the pieces “it.”With infrastructure, it’s very important to understand what makes it unique.  Infrastructure systems do not, by and large, directly handle tasks for you. Instead they provide a life support system for the applications that work for you. On a good day you hardly notice infrastructure. That’s the point of good infrastructure.  That’s also the problem.  Here are five unique traits that make infrastructure management very challenging. 


5. Infrastructure is mostly invisible Infrastructure is so established as a conceptual term that we forget its original, literal meaning – the structure underneath. It supports everything above, but it is hidden from sight. In fact it is supposed to be hidden.


 The fact that most users don’t think twice about infrastructure is a feature, not a bug; good infrastructure does its job by letting applications do their jobs, so that end users can do their jobs.Because of this, most people in an organization, including users in the front office and other key players, don’t really know much about infrastructure. Indeed, they may hardly be aware of it.  If your infrastructure team or provider is good, no one thinks about it at all.It needs to be thought of.  Because someday  . . . 



4. Infrastructure will get noticed when it breaks Once infrastructure breaks?  Then everyone notices infrastructure, and they want it fixed now.  Who can blame them?  You’ve experienced the same thing when something you rely on but rarely think of – a car, a phone, an air conditioner – breaks.  You want it fixed, and you want it fixed now.With infrastructure it’s even worse – because you’re so used to it working you may not have it  contingency plans.  It always worked until now . . .



 3. User-unfriendly interfaces Infrastructure is designed by specialists for specialists. Most end users are not expected to deal with it, or even really be aware of it. 


They simply use the applications and processes that the infrastructure supports.  


This is how it should be.This means that infrastructure interfaces are built largely by people who have been dealing with similar specialized interfaces for years.


 Even for it professionals, if they are not deeply familiar with a particular system, the interface can be full of surprises.

 And when it comes to critical systems, surprises are never welcome.Good documentation (so often a dirty word to many) and good planning can ensure this is less of a problem.  It may not be glamorous, but then again that’s kind of the point of good infrastructure – it should never be exciting, because exciting means a crisis.


 2. The devil is in the detail Infrastructure systems are devil-rich environments, filled with pitfalls even for the experienced and wary. 

This, too, is really a feature, not a bug. Good infrastructure keeps the devils down below, safely away from end-user applications. 
Build and versioning systems keep track of version details so that you don’t have to. Computer farms let you crunch numbers without thinking about where exactly the crunching happens.
But the cost of keeping end-user applications running smoothly is lots and lots of technical-detail devils down in the infrastructure – just itching to get loose and cause trouble in the applications up above.This goes beyond the problems of confusing interfaces and into the realm of sheer complexity. 
 A good set of documents, a good wiki, and smart recruiting and training can help you keep the devils where they belong.


 1. Everyone depends upon it and you can’t get away If infrastructure stops working, so does everything and everyone who relies on it.

  You can be sure if you work at a company of any size, you are more dependent on infrastructure than you know, right now.Which means that infrastructure management is, for many organizations, no place for do-it-yourself, casual work, or legacy setups.
 You want someone who has a deep and broad understanding of infrastructure processes, who can keep the infrastructure running smoothly, and get it back in order quickly when something goes wrong. 
 You need the right plan and the right resources, from an expanded it team to outsourcing systems to proper experts.

Each challenge can be dealt with, of course, but being aware of them is the first step to being able to ignore infrastructure again – for the most part.
