BPM, RPA, and Low-Code compared for process digitalization

Let’s compare the tools for digitization and process automation: among RPA, BPMS, and low-code, which is the most suitable solution? If we choose low-code, can we be sure that we are selecting the most appropriate platform for the intended use? There are several evaluation factors—discover which ones.  

According to Gartner, by 2025, 70% of organizations will have implemented some form of structured automation, a significant increase from just 20% in 2021. However, many companies remain heavily reliant on manual and paper-based processes in key areas. For instance, 70% of invoice processing globally is still paper-based , and the time required to process them compared to digitized ones is four times longer, with clear negative implications for business speed and efficiency.   

Some manual tasks, such as data integration, are gradually decreasing thanks to the adoption of Artificial Intelligence, but a large part of business processes remains non-automated. Process digitalization presents various challenges and complexities: issues stemming from shadow IT, the misalignment between business and IT in implementing new technologies, with the former wanting to move quickly. There are also constraints related to legacy technology, which requires specific technical skills and constant maintenance.  

However, the biggest problem is not just the existence of paper-based processes: even when digitalized, processes are often managed through a network of disparate systems. Unstructured processes, such as Excel files, emails, phone calls, are still used to extract value from the data contained in them. This prevents the full integration of these processes to achieve a completely digitalized end-to-end workflow 

IT leaders are turning various tools to enable process digitalization, but each technology has limitations, being specific to certain purposes. What considerations must be made to ensure the right solution is chosen to meet growth and evolution objectives 

Between the integration of heterogeneous systems, collaboration with a variety of stakeholders, ensuring investment in a long-term automation strategy, finding the right tool to move manual or paper-based processes online , or creating seamless digital flows between existing processes, finding the right solution can seem impossible. Is it better to look at standard automation tools? Or at low-code development to create custom applications and microservices?  

Even if low-code seems like the ideal choice, the decision-making process doesn’t end there, as there are multiple technologies to consider. There are those used in the context of individual SaaS to connect screens and workflows to a database, but also more complex enterprise solutions that integrate various data sources and existing business systems 

The automation strategy must always be adapted to the needs, complexity, and use cases of your organization. Their exact implementations may differ, but they must all start by addressing a series of similar questions:  

  • What is the vision? In other words, what is the long-term automation strategy? 
  • Who is responsible for developing the solution within the organization?  
  • What types of use cases and complexities are being addressed?  

What automation tools do we have available? 

Companies can rely on various solutions, which we outline here: 

  • RPA (Robotic Process Automation), i.e., technologies specialized in automating repetitive tasks like data entry. Combined with AI (Intelligent Automation), they can become more “intelligent” and be used for more advanced decision-making processes. 
  • Business Process Management (BPM), technologies for structuring and optimizing business processes.  
  • Low-code/No-code platforms: tools to create applications with minimal technical expertise, without the need to write code from scratch. 

Let’s start with Business Process Management Software (BPMS): this type of software integrates visual modeling, analysis, and automation tools to manage complex processes involving multiple people, systems, and applications. 

These technologies can be used in various scenarios: managing expense approval processes involving employees, managers, and finance teams, recruitment processes with task assignment across various departments (HR, IT, administration), order management, etc.  

Within these tools, users create diagrams based on standards such as BPMN (Business Process Model and Notation) , which describe the activities, decisions, and roles involved in a process.  

The visual modeling, supported by analysis, simplifies understanding and communication of the process, facilitating the optimization and automation of complex workflows. 

  • Advantages of BPMS: ideal for managing complex processes and intricate business cases.  
  • Disadvantages of BPMS: complex to implement, requires programming skills, lacks ease of use and accessibility for non-technical users.  


Mapping
Robotic Process Automation (RPA) as a technology that uses software, or “bots”, to automate repetitive tasks through user interfaces, web pages, and terminal applications 

The unique feature of RPAbetweenis their ability to interact with graphical user interfaces (GUIs), not just APIs or code, making them ideal for automating repetitive, rule-based tasks. These rules define the flow of operations that the bots must follow, such as transferring data, sending emails, or updating databases. This makes them perfect for predictable, routine tasks, where actions can be defined by a series of precise and repeatable instructions. 

  • Advantages of RPA: excellent for automating repetitive, rule-based tasks. Does not require changes to existing IT systems and saves time on manual operations. 
  • Disadvantages of RPAcan be complex to scale in environments with variable processes, as it is confined to individual tasks strictly based on fixed rules. In some cases, maintenance can be burdensome if the underlying systems frequently change.  

Now let’s dive into low-code development.  

This type of solution allows for the creation of applications with minimal use of code, thanks to visual interfaces and drag-and-drop tools. They are designed to enable both professional developers and non-technical users to to create apps quickly and easilywithout having to write complex code. Development times for web or mobile applications are therefore significantly reduced compared to traditional methods, facilitating the automation of business processes.   

Not all low-code platforms are the same, as they differ in target audience and functionality. Let’s take Power Apps and Mendix as examples: they share the goal of simplifying application development but… 

  • Power Apps is designed for non-technical users (“citizen developers”) who want to create simple applications and automations, primarily within the Microsoft ecosystem (such as Office 365 and Azure). 
    It is ideal for development projects requested by non-technical users with well-defined guidelines and application scopes within the Microsoft ecosystem. It can be used, for example, as an extension for integrated products like Microsoft 365 or Dynamics, where the addition of simple screens or workflows is required.

    On the other hand, Power Apps is limited for complex enterprise solutions and large-scale scenarios , as advanced customizations and integrations outside the Microsoft ecosystem can be challenging. Achieving a certain level of complexity within the Microsoft suite may require piecing together a solution using several tools like Power Apps and Power Automate.
     
     

  • Mendix, however, is better suited for complex enterprise environments and can be considered a,low-code enterprise platformfor large-scale projects that require advanced customizations and deeper integrations. When building sophisticated and complex applications within a structured software development process, with quality requirements comparable, for instance, to SAP or high-code standards, Mendix is the right choice.  
     

Simply put, we could say that Power Appsis a low-code solution based on single-user or function-based, while Mendix is a more enterprise-oriented solution. enterprise-based 

Power Apps is typically used to develop individual applications or for small teams with specific needswithout involving a complex IT infrastructure. 

Mendix, on the other hand, is an enterprise-oriented platform, as it allows the management of larger and more complex projects with a significant number of end users, often distributed across various company divisions or multiple global locations.  

Complexity indicators for choosing between Power Apps and Mendix 

When choosing between Power Apps and Mendix, consider these complexity factors: 

  • Types and volumes of integrations 
    If a low-code platform is to be used as an extension for other complex solutions, such as SAP, Mendix is considered a “strong” platform due to its ability to deeply integrate with various systems (including SAP).

    In fact, Mendix is the only low-code platform that is anSAP Endorsed Appand has earnedSAP Premium Certification, which allows for deep integration with SAP solutions, enabling the creation of extended applications that work directly with SAP Business Technology Platform (BTP) and other SAP applications, such as SAP S/4HANA and SAP SuccessFactors​.  

    Conversely, Power Apps works optimally primarily within the Microsoft ecosystem, such as Office 365, Dynamics, and Azure, and is therefore less flexible for complex external integrations. 
     

  • Need for mobile applications  
    if applications need to be used via mobile , also consider how advanced the support for mobile app creation is.

    Power Apps’ user interface is optimized for predefined templatesbut may present limitations when adapting the application to different devices. For instance, when developing a desktop browser or an iPhone, it is often necessary to build multiple versions of the user interface (two or three) to ensure a good user experience on all platforms.  
    Mendix, on the other hand, offers native support for mobile app creation. The platform allows for the development ofnative, hybrid, and web applicationswith a single interface that automatically adapts to devices (Android, iOS, and browsers) without the need to create separate versions of the user interface.  
     

  • Volume of end users 
    It’s also essential to consider the complexityandscalability of the applicationseach platform will need to support. Power Apps is bettersuited for simple solutions and apps with a limited number of end users or for small companies. These apps are often focused on individual departments or internal projects: they have a low volume of users and limited technical requirements.
     

Mendix, on the other hand, is designed tohandle more complex enterprise applications, suitable forfor medium to large organizationswith ahigh volume of end users. It is highly scalable and can manage not only thousands of users but also applications distributed across various departments or even on a global scale. Thanks to its support for complex applications, flexibility in integrating with various systems, and the use of enterprise-grade cloud infrastructures, Mendix is ideal for mission-critical applications with a high volume of users.
