You are the CIO. Or, the director of application development. You hear about consumerization of IT, in different contexts. You hear about mobile applications developed by teenage kids in only months, and these apps are used by millions of adoring people. And, your business people are demanding why can’t be more like those kids.

What should you do? Retrain your staff on some of the consumer technologies? Get a partner who has the skills in the consumer technologies? Move existing applications to consumer-friendly devices? Are they enough? And, why are you doing all these anyway?

In last couple of years, I have been working with different IT leaders to evolve a definition and an approach to this problem. By training, I am a technology person – the kind that develops the consumer technology. By vocation, I help IT departments help adapt technology to meet their strategy. Being in both the sides of fence, I have a perspective that may be interesting.

This note is derived from a few presentations I made at different industry conferences. The self-explanatory slide deck is available at: http://www.slideshare.net/kramarao/consumerization-32279273

Let’s look at the following three questions, in order:

  1. What is consumerization of IT?
  2. How does it affect IT departments?
  3. What should the IT departments do about it?

Consumerization of IT: A bit of history

The as coined in 2001, consumerization refers to the trend of building application that are people centric. Have we not been doing that always? Yes and no. While we were developing the applications for people, our main focus was some where else. The focus was about either growth of the business (by managing the volume of data), automation of activities to speed up the processes, or automating the entire business value chains, or only recently, focusing on the customers.

When we were building applications earlier, we were building them for a purpose: to solve a business problem. People were another peace of the puzzle – they were meant to be a part of the solution, but not the purpose of the solution.

Enterprise IT application development

How are these applications developed? Take a look at the sample development process.

In the current traditional situation, the EA people map the needs of an enterprise to a technical gap, see if there is a packaged app, and either customize one or build a new one. The biggest questions often boil down to “Build vs. Buy” or, what to buy.

A few things that you will observe are these:

  • Applications take long time to develop: Typically they are large, and serve long term needs of the enterprise. Any other kind of applications are difficult to retrofit into this model of development. For example, if you want an application by marketing department for one-time event, existing processes of IT makes it difficult to offer that service. That is why, we find marketing is one of the prime movers behind consumerization.
  • Applications serve common denominator: They address most common needs of the people. If your needs are very different from others, they will be ignored, unless you are the big boss. No wonder, that IT departments still develop applications with “Best viewed on IE 6+” sticker.
  • Applications lag behind the market needs:  Since the focus is to create the applications with longevity, the design uses tested technologies. The pace at which these technologies are evolving, this design decision makes the technology foundations obsolete by the time applications are delivered. For example, even today, IT departments use Struts in their design – a technology that is already dead.
  • Applications, developed based on consensus needs, lack focus: Since there is a going to be one large monolithic application meeting requirements of several groups with different needs, the applications lack focus. For example, the same application needs to support new users and experienced users. Or, it needs to support management interested in the big picture view and the workers interested doing the processing.  Naturally, any application that is developed to such diverse and divergent needs ends up being unfocused.
  • Applications are expensive to develop: Compared to consumer apps, where we hear apps getting developed for a fraction of cost, the process and the “enterprise quality” requirements impose lot of additional costs on the application development.

That is, this process yields applications that are built to last.  Let us look at how consumer applications are developed.

Consumer application development

Historically, consumer applications have been developed differently.

As you can see, in each era, the consumers are different; the focus is different; and the distribution mechanism is different. File it away, as this historic view is important as we look at consumerizing IT. Dwelling deeper into the current era, we see the following:

image

Consumer applications almost always are better focused on end results than the users needs. For example, take the case of Instagram. In its history, it discovered if it followed user needs and demands, it would end up being another FB clone. Instead, it decided to keep the focus on one metric: “How to get most number of photos uploaded by the consumers”. That focused design led to its success.

Consumer applications are also built in collaboration with the consumers. By creating a model of constant experimentation, feedback from the field, and ability to improve the application, without ramifications of user support, the creators of the applications are able to build systems that are “built for change”.

But, what are the disadvantages for the consumer applications, compared to enterprise applications?

  1. Only interesting applications get developed: Go to Apple’s app store, and you find so many applications around weather apps or gaming apps. You do not find enough applications to do genome analysis. Developers are impatient with problems they do not understand, or the problems that require lot of knowledge to solve.
  2. Capabilities may be replicated in many applications: The strength in consumer applications, namely catering to different groups of people, means some core functionality gets repeated in applications. Instead of getting high quality apps, we might end up with lot of apps that are mediocre.
  3. Lack of uniformity in solutions (depends on the platform): While some platforms are famous for creating a uniform and consistent experience, the applications themselves, provide fragmented experience.  Unlike enterprise applications, they lack control or governance.

Consumerization: Why should IT care?

We established that enterprise applications and consumer applications have different focus. We also established that they are built, distributed, and operated differently. Still, why should IT care about consumer applications? Why should it consumerize itself?

I can think of three reasons.

Consumer focus of the businesses

Several service industries like retail, banking, entertainment, music, and health deal with consumers daily. Their business models are being disrupted by startups that bring new technologies and new breed of applications. While IT does not exactly lead the business transformation, at least by bringing the right capabilities, IT can support businesses better.

Internal users as consumers

Demographics of the employees are changing. More and more young people are joining the workforce. They are used to different kind of experience using modern devices and modern applications.

Even the older people are used to consumer applications: they use Gmail at home, facetime on their IPad, Facebook on their laptop, and LinkedIn at work. They come to work and they use Exchange without the benefit of Bayesian spam filters; they use Lync video instead of facetime or Hangouts; they do not even have something like Facebook or LinkedIn at work.

By not exploiting the modern technologies and application paradigms, enterprises are risk losing productivity and ability to attract the right talent.

Cheaper and better Consumer technologies

Large investments in the consumer technologies are making them cheaper and better, at a faster pace than the enterprise technologies. For instance, git is improving at a faster pace than perforce. Those companies that took advantage of the cheaper alternatives in consumer technologies, reaped the benefits of cheaper and better infrastructure, application construction, and operations. Google built their data center on commodity boxes. Facebook leverages open source technologies fully for their needs. The following are the main reasons why the consumer technologies are often better choices than the enterprise grade technologies.

So, considering that enterprises are being pushed towards consumerization, how should IT react?

Consumerization: an IT perspective

The best course of action for IT is to get the best of the both worlds. On one hand, it cannot run business as usual without its control and governance. On the other hand, it cannot react to markets innovatively without the consumer technologies.

image

As we bring both these best practices together, we see some interesting facts emerge. At least for certain aspects of application domain,  we see that old style of large scale application development does not work.

image

As consumerization increases,  we end up with large number of small applications instead of small number of large applications. Of course, the definition of application it self is subject to change. For our purposes, consider any isolated, independent functionality that people use to be an application. Historically, we used to talk about modularizing the application. Instead, now, we break down large application into smaller pieces. Some of these smaller pieces may have multiple versions to suit the extreme segmentation that consumerization supports.

If we are moving towards such IT landscape, what does it mean to traditional activities? In fact, all the following are impacted by this aspect of consumerization.

  • Development
  • Life cycle plan
  • Deployment
  • Support
  • Governance
  • Enterprise Architecture

Let us look at some of these challenges.

Challenges in consumerization of IT

I see three challenges in consumerizing IT.

These costs are easy to rein in, if IT can bring in some of the consumer technologies. In the next section, we will describe each of the technology changes that can help IT address these challenges.

Coping with consumerization: A recipe for IT

There are four questions that we should ask ourselves as we are embarking on consumerization of IT:

image

Each of these questions require an adjustment to the way IT operates. Each of these key concepts need full explanation. Since this article already has grown long, I am going to be brief in describing the key concepts.

Pace layered architecture

The idea behind pace layered architecture is that different parts of the IT move at different speeds. For instance, front end systems move fast as the technology advances faster there. The ERP packages move slow, as they focus on stability. Based on this idea, we can divide IT systems into three groups:

  1. Systems of record
  2. Systems of differentiation
  3. Systems of innovation

If we were to divide systems this way, we know where consumer technologies play a big role: systems of differentiation and innovation. To take advantage of this idea for consumerization, I recommend the following steps:

Platform based development

Typically, when we develop applications, we are given just a set of tools that we can use: Java, app server, database etc. Putting together these parts into a working application is left to the developers. At best, standard configurations are offered.

Most of the tasks developers need to do are standard: add security, add user authentication, add help text, add logging, add auditing, and so on. Considering that there are lot standard tasks that developers need to do, is there a way that we can reuse the effort?

We have been reusing different artifacts in several ways. We used libraries, templates, and frameworks. With the advent of cloud technologies, we can even turn into a platform that is ready for cloud. Platforms turn out to be useful in several ways: they standardize development; they reduce the costs; they reduce the time to get the systems ready for development; they improve quality of the systems.

In addition, within any enterprise, there might be standard best practices that can be incorporated into the platform. With these additions, we can enforce governance as a part of the platform based development.

There are industry standard platforms as well for specific purposes: Google platform, Facebook platform, Azure platform, and SFDC platform. Each of them offer different capabilities and can be used for different purposes. Instead of standardizing on one platform, an enterprise will have to classify its needs and plans, categorize its applications, and from that basis, devise multiple platforms for its needs.

Internally, Microsoft has positioned SharePoint services and Office 365 as such a platform. Coupled with .NET technologies, it can be a full platform for delivering user defined applications.

Backend as APIs

The potential of the platform can be fully realized if the enterprise data and functionality is available to the apps developed on the platform. For instance, the data locked in the ERP applications is valuable for many modern applications. Existing logic within the system is difficult to replicate elsewhere and may be needed by the application.

By providing this information, both data and logic alike, as API’s, we can enable internal application as well as external applications. In fact, the current application development paradigms around API based front end development offer several different frameworks for this style of development.

Using REST+JSON API’s, we can develop web as well as mobile applications from the same backend.

Modern app stores

Once applications are developed, they need to be operational for the people. There are four different aspects to putting applications to use.

image

There are several different ways such an app store or platform for delivery is handled historically. Popular choices for different ecosystems include, Apple’s app store, Google Play, FB Apps, etc. If we build it right, we do not have to restrict the app store to mobile applications alone. Instead, the same delivery and support mechanism can support mobile and web applications as well.

Concluding Remarks

Consumerization of IT is a desirable trend, if handled correctly. The right way to handle to bring the useful elements of consumerization to appropriate kind of applications. The core features from consumerization include conceptualization of apps via pace layered architecture, development via platforms, integration via API’s, and delivery via app stores.
