Definition of Low Code Development

Low code development sets aside text-written coding practices and takes a more visual approach. Instead of a coding environment, low code development works with a model-driven drag-and-drop interface.

Business owners and stakeholders can leverage the visual modeling approach to develop value-driven enterprise-level applications.

How Does Low Code Development Work?

In traditional software development, the team has to write hundreds of lines of code to represent actual data. Then they organize the codes into functional routines and modules that provide features and functionality of the software itself.

The traditional approach requires deep knowledge of all the aspects related to software development, such as:

  • Programming Languages
  • Integrated Development Environments
  • Code Compilers
  • Testing and Deployment Tools
  • Coding Policies and Practices
  • Testing and Deployment

Compared to low code, traditional development sounds like a tedious and tiring process since low code, as the name suggests, takes away most of the coding and replaces them with visual representations of different functions created with coding.

Principles of Low Code Development

Though low-code leverages automation, not all the development processes are automated entirely. Every software developer should understand the development principles to get the best results from low-code app development.

1. Understand The Platform Itself Before You Start

It’s not just about the developer team; all non-technical business stakeholders should also understand the platform just as much so they can join in on the process and contribute to improving the application.

2. Avoid Customization Unless Needed

It’s very easy to rapidly improve the application by customizing the existing modules or improving new ones; it also contributes to additional costs. The changes, however easy to implement, can drive up the development time and result in diminishing the benefits of low-code development.

3. Generalize Customizations

Ife If the application requires customization, consider common use goals when implementing features and the UI. Design all components in a way that they can be reused later on.

4. Never Overlook Your Team

When a team selects any low-code platform, they do so once they understand all the intricacies of the development platform itself. Stakeholders should always value the team’s opinion and collaborate to answer all the team’s questions to improve the final product.

5. Your Business Should Lead Your Roadmap

Low code makes experimentation accessible. But you shouldn’t let that distract you from the true goals of your business. Experimenting with new features and ideas may give you an idea about what the audience might like, but that shouldn’t drive the development life cycle away from your brand.

Features & Benefits of Low Code Development

Now that the basics are covered let’s look at the noteworthy features of low code development and the benefits they provide.

1. Visual Modeling

Low-code development platforms rely on visual models utilized through a drag-and-drop interface. The interface allows citizen developers to get involved with the development directly, visualize their idea, communicate with the developers, and help them implement the required features.

Benefits of Visual Modeling:

  • Helps utilize existing talents for faster development
  • Empowers all departments to join in the development process
  • Allows development of high-level functions with low costs
  • Promotes better decision-making with cross-functional teams
  • Frees up specialized developers to work on complex projects

Challenges of Low Code Development

Despite the countless benefits, of which we only mentioned five, you will face a few challenges when taking the low-code software development approach.

1. Requires More Knowledge Beyond The Tools

Even though low code is accessible to almost everyone, it can’t bypass the need for skilled developers and a well-designed infrastructure. Creating an app, regardless of the scale, requires advanced knowledge of enterprise software development and general business practices.

Creating an app that reaches the required business goals can become a struggle if your staff lacks enterprise software knowledge.

Even with low code, the developers must have additional knowledge of software development and knowledge about the business process itself.

2. The Code May be Inefficient And Unoptimized

One of the best benefits of low-code application platforms is that they can utilize pre-built templates or reusable components for applications. But there’s also a catch. Reusable components mean that similar codes are present in the build, which can cause the software to become bloated with unnecessary underlying code in the infrastructure.

When creating software, the goal is always to reduce the excess code to reduce size and optimize functionality. With reusable components and nearly identical codes, optimizing the application for all systems to reach the required speed is tougher.

3. The Real Complexity Lies Under The Hood

Low-code software is the best when the codes and functions work as intended. But here’s a short question for suspense: what if it doesn’t?

There are times when the software may not work as expected. Sometimes, the software may function poorly, even after thorough testing and optimization. The app may not fully comply with all the security requirements, leaving major vulnerabilities compromising everything.

To understand the real reason behind these anomalies, one or more people must be present on the team who have comprehensive knowledge of every single detail of a low-code application development platform and all its different aspects. Under the simplicity of low code lies an intricate structure that many struggle to comprehend without the right mindset or knowledge.

4. The Use Cases Are Limited

Though low code is mostly the best choice, there are still a lot of business problems out there that can be solved even more efficiently with traditional software development and the toolset that comes with it.

Low code can offer a high range of customization and integration, but sometimes these processes are too complex to drag and drop the problem away. It requires manual programming and scrutiny, and that’s when traditional app development tools are e better fit for the situation.

5. Potential Vendor Lock-In

Any low-code platform can allow you to create apps with a combination of visual models and custom coding. But if they only work within the platform and not on other platforms, you are a victim of vendor lock-in.

Unless you’re working with low-code platforms like Mendix, there is a chance you might get stuck with a vendor lock-in for the lack of better compatibility.

Who Can Build With Low Code?

Professional Developers

Low code development platforms offer a dedicated IDE and sophisticated toolbox to support client-side, server-side, and integration development simultaneously.

  • Professional developers can leverage custom coding to:
  • Extend the functionalities of the current application
  • Integrate data from multiple sources
  • Build mobile applications
  • Leverage different microservices
  • Translate business needs to customer solutions

Business Developers

Business developers can utilize the simplified development environment of low-code platforms to develop their apps, and they don’t even need the help of the IT department!

Low code empowers citizen developers to create basic applications even without development prowess or advanced knowledge. They can also create prototypes that developers can interact with to understand the different functions they need to implement, customize or extend.

Enabling citizen developers also increases governance over the project with direct control and reduces shadow IT.

Low Code Use Cases & Examples

These are the five most popular use cases for low-code solutions.

1. Web Portals

The most common and popular method for a customer to interact with any business is through a web portal. Through a web portal, a customer can:

  • Find Services or Products
  • Get Quotes
  • Check Resource Availability
