Low-code maturity boosts efficiency and helps user acceptance

By Lindsay Clark

Low-code development is finding new maturity in enterprise application development, and organisations of all kinds are taking advantage of the trends. According to Forrester Research, spending on low-code software development is set to reach $21.2bn by 2022, growing by about 40% each year.Although it was initially considered a boon to mobile and web application development, as confidence in the market increases, businesses are trusting the concept to improve productivity in enterprise business applications, says Eduardo Cruz, vice-president UK and Ireland at OutSystems, a low-code platform supplier.

“Through the years, we have focused on delivering great applications for mobile and web platforms, but we have shown most software is faster to build and easier to change and maintain using low-code,” he says.

Low-code suppliers promise a largely graphical, drag and drop approach to building applications, although some coding might be necessary to link to other IT infrastructure. It differs slightly from the no-code concept, which promises a purely graphical developer experience.

But developers still need to aware of the overall IT environment, says Cruz. “If you are building a core system, you need to be mindful of that architecture. Low-code does not mean lack of architecture or lack of security and testing.”

With that in mind, developers can build robust applications with low-code platforms. For example, Nationwide building society has just started building a digital banking platform using the OutSystems platform.

“The fact that they are building customer-facing apps but also processes that run in the back office and integrate with enterprise application – that is the biggest recommendation of the approach,” says Cruz.

Rapid development in response to user needs

Although the term low-code was coined by Forrester in 2014, to some the concept is not new.

Supplier Pegasystems was founded in 1983 and began by capturing user requirements on forms presented on mainframe green-screen systems. While it has developed its products through the client-server era to the cloud, the focus remains on rapidly developing applications that stick close to user needs, says chief technology officer Don Schuerman.

“It’s about how you take a process and chunk it down to a micro-journey to build and deploy the application, whether that is managing customer billing, or a vaccine clinic. It all comes down to finding the business process and chunking it down,” he says.

The recent demand for low-code development comes from a desire to modernise IT environments quickly without taking a rip-and-replace approach, says Scheurman. “The push from the business on software development is to do things fast. They also want to automate. That is why I think low-code and robotic process automation (RPA) are part of a continuous spectrum.”

Nick Ford, vice-president of product and solution marketing at low-code supplier Mendix, agrees that the hidden benefit of low-code is meeting user needs. “What often happens is there is an impetus for an idea – a new insurance product, for example,” he says. “That might be built as a prototype by a subject-matter expert who creates the data model on-screen in low-code, but over time that is fleshed out and made production-ready, including integration with back-office systems, by a developer collaborating on the same model. It is not waterfall – they have different windows into the model to do different things.”

In this way, the IT department can set guide rails for data governance and security before applications go live. The approach also helps gain user acceptance of apps, which has been particularly important for Mendix customer Mencap, a UK charity which used the system to develop apps for its workforce of carers (see box: Mencap gets closer to users’ needs with low-code).

Understanding of the low-code concept received a fillip when the world’s dominant operating system and desktop application software firm, Microsoft, entered the market in 2016. Its PowerApps environment allows business users to develop their own apps, and even make the shift into the IT department (see box: PowerApps helps Autoglass bring business skills into IT).

Cloud customer relationship management (CRM) software supplier Salesforce also offers a set of low-code tools which help users on its own cloud platform. Appian is another notable supplier, which says it makes application development 20 times faster with fewer resources.

Gartner research director Paul Vincent says typical application development times have been cut to between two to three months using low-code technologies, compared with six months to two years for development using more conventional approaches. Users picking a low-code environment should be aware of the differences between large and small suppliers. Whereas the big firms such as Microsoft and Salesforce only allow the development of applications to run in their own environments, smaller suppliers can help build applications which can be ported to a number of different environments, including on-premise software stacks, says Vincent.

Low-code a popular choice

While much of the interest in low-code has been generated around business teams developing their own applications, the biggest users of low-code environments are developers themselves, he says. “Compared to conventional application development,such as using Red Hat OpenShift, Pivotal or Cloud Foundry, where developers may need to be combining applications with multiple other components in API [application programming interface] gateways, in low-code all the capabilities for things like integration, a database, and so on, are built-in, and you don't need to configure them. You just need to use them effectively. That's really one of the biggest changes,” says Vincent.

The popularity of low-code development has been evenly spread through industries, he says. “Usually, you expect take-up of a new technology to be dominated by industries like finance and telecommunications, but low-code is applicable across the board. We see it, for example, in governments, which find it a very good fit because they lack IT skills and have a limited budget.”

While low-code is not new, the freshly coined moniker is attracting the attention of IT users. It promises not only to accelerate the development of software, but also improve the capture of user needs and, ultimately, boost buy-in for new applications, helping them achieve their business objectives. It is as popular with developers as it is with business users and promises to reshape the relationship between IT and business users.
