I read an article a while ago in InforWorld entitled, “The unintended consequences of forced BYOD.” The Bring Your Own Device (BYOD) phenomenon will only gain in strength because more people are using their mobile devices for everything they do and corporations are continually looking for ways to improve the bottom line. The push from both sides ensures that BYOD will become a reality. The article made me think quite hard about how developers who work in the BYOD environment will face new challenges that developers haven’t even had to consider in the past.
Of course, developers have always had to consider security. Trying to maintain a secure environment has always been a problem. The only truly secure application is one that has no connectivity to anything, including the user. Obviously, none of the applications out there are truly secure—the developer has always had to settle for something less than the ideal situation. At least devices in the past were firmly under IT control, but not with BYOD. Now the developer has to face the fact that the application will run on just about any device, anywhere, at any time, and in any environment. A user could be working on company secrets with a competitor looking right at the screen. Worse, how will developers legal requirements such as the Health Insurance Portability and Accountability Act (HIPAA)? Is the user now considered an independent vendor or is the company still on the hook for maintaining a secure environment? The legal system has yet to address these sorts of questions, but it will have to do so soon because you can expect that your doctor (and other health professionals) will use a mobile device to enter information as well.
Developers will also have to get used to working with new tools and techniques. Desktop development has meant working with tools designed for a specific platform. A developer would use something like C# to create a desktop application meant for use on any platform that supports the .NET Framework, which mainly meant working with Windows unless the company also decided to support .NET Framework alternatives such as Mono (an open source version of the .NET Framework). Modern applications will very likely need to work on any platform, which means writing server-based applications, browser-based applications, or a combination of the two in order to ensure the maximum number of people possible can interact with the application. The developer will have to get used to the idea that there is no way to test absolutely every platform that will use the application because the next platform hasn’t been delivered yet.
Speed also becomes a problem for developers. When working with a PC or laptop, a developer can rely on the client having a certain level of functionality. Now the application needs to work equally well with a smartphone that may not have enough processing power to do much. In order to ensure the application works acceptably, the developer needs to consider using browser-based programming techniques that will work equally well on every device, no matter what level of power the device possesses.
Some in industry have begun advocating that BYOD should also include Bring Your Own Software (BYOS). This would mean creating an environment where developers would make data available through something like a Web service that could be accessed by any sort of device using any capable piece of software. However, the details of such a setup have yet to be worked out, much less implemented. The interface would have to be nearly automatic with regard to connectivity. The browser-based application could do this, but only if the organization could at least ensure that everyone would be required to use a browser that met minimum standards.
