One of the main goals of leading IT figures is to try to improve the productivity of the IT department they manage. One way to achieve this goal, and one that is becoming increasingly popular among organizations of all industries and sizes, is to leverage composable and reusable elements. In addition to optimizing productivity and speeding up the development process, this solution also ensures [better governance](https://blog.mia-platform.eu/en/better-governance-through-composability-reuse).

These reusable components, known as [packaged business capabilities (PBCs)](https://www.gartner.com/en/documents/3976170), belong to a specific type of packaged application that encapsulates distinct and self-contained business functionalities. By embracing this modular approach, organizations can rapidly assemble and deploy digital capabilities without the burden of time-consuming development from the ground up.

When implemented effectively, PBCs hold immense potential for organizations worldwide. By the end of 2023, [around 30% of new applications](https://www.netsolutions.com/insights/composable-architecture-why-its-important/) are projected to be built using PBCs, a remarkable increase compared to the mere 5% recorded in 2020. PBCs' modular components enable organizations to streamline development processes, reducing time and costs.

This article discusses PBCs and their remarkable capacity to revolutionize building and deploying software. Taking a close look at its characteristics, applications, and value, we discuss how PBCs address the limitations posed by traditional architectures.

 

## What are PBCs?

[Packaged business capabilities](https://www.gartner.com/en/documents/3976170) are standardized, pre-packaged software components representing specific business capabilities and functions.

PBCs are self-contained modules consisting of a data schema and a collection of services, APIs, and event channels. PBCs are functionally complete and usually have all the necessary resources to operate independently without relying on external components. This autonomy is achieved by minimizing critical external dependencies and eliminating the need for direct access to its data.

 

**Are microservices the same as PBCs?**

[Microservices (or microservices architecture)](https://blog.mia-platform.eu/en/microservices-the-architectural-style-for-modern-applications) are a [cloud-native](https://www.ibm.com/topics/cloud-native) architectural approach in which a single application comprises many loosely coupled and smaller deployable independent components or services. Although microservices and PBCs promote composability and reusability in software development, they are not the same.

The key difference in principle between microservices and PBCs is that microservices are an architectural style that defines how we break down applications into services. These services can communicate through APIs; each can be developed, deployed, and scaled independently. However, PBCs are custom combinations of certain microservices that work together to carry out a specific business function.

To better grasp the distinction, consider this example: In the microservice approach, a microservice might be responsible for handling user registration, another for login, and a third one for managing user profiles. However, a PBC might take our entire user authentication flow.

Microservices, although valuable, can be difficult to handle for the average business user, as they are complex and challenging to maintain.

 

## Redefining Limitations: Monolithic Architectures vs. PBCs

For years, [monolithic architectures](https://blog.mia-platform.eu/en/from-monolith-to-microservices-how-you-should-evolve-your-legacy) have been the bedrock of organizations. Although they serve their purpose, when these architectures are confronted with the demands of the digital age, they reveal their vulnerabilities and crumble.

Some of the challenges that plague monolithic applications are listed below.

- **Rigidity**: Unlike PBCs that utilize modular interchangeable components, traditional monolithic architectures are effectively a single unit, making them resistant to change and innovation, especially as size increases.
- **Scalability challenges**: Scaling individual components within a monolithic application can be challenging. It is inefficient and prone to resource waste, hindering organizations from effectively meeting fluctuating demands.
- **Inhibiting innovation**: The [tightly coupled](https://glossary.cncf.io/tightly-coupled-architectures/) and intertwined nature of components in monolithic architectures limits experimentation and innovation.
 

## Applications of PBCs

Practical applications of PBCs are found across different industries and business teams. Some of the key applications include the following cases.

 

**Supply chain management (SCM) systems**
[The SCM system is a company's software system](https://www.ibm.com/topics/supply-chain-management) used to manage the entire flow of goods and services, incorporating all processes in transforming raw materials into finished products. The integration of PBCs in this process helps to optimize this whole flow, as it may include capabilities like demand forecasting, inventory optimization, logistics management, supplier collaboration, etc.

 

**E-commerce and online marketplaces**
Online [retailers](https://mia-platform.eu/solutions/retail/) and marketplaces leverage PBCs to handle payment processing, inventory management, order fulfillment, and customer support. PBCs allow them to focus on their core business without investing heavily in developing these functionalities from scratch.

 

**Financial services**
[Financial industries](https://mia-platform.eu/solutions/mia-fintech-banking/) can harness the power of PBCs for risk management, fraud detection, trading platforms, and more. These capabilities allow organizations to build robust and secure applications without the need to build everything from the ground up.

 

## Approaches to building and reusing PBCs

Organizations can select from various approaches when constructing PBCs tailored to their unique goals and needs. These approaches involve strategies for integrating and leveraging third-party solutions and resources. In this section, we explore these approaches, discuss their considerations, and highlight the benefits they provide.

 

**Standalone implementation approach**
The standalone implementation approach involves deploying PBCs as separate, independent systems within an organization's infrastructure, and some of the benefits of this approach include the following.

- **Isolation and flexibility**: With PBCs operating separately and independently, the risk of widespread failures is reduced. Isolation can reduce or eliminate the need for external dependencies and thus increase system flexibility.
- **Customization**: Organizations can tailor each PBCs to their requirements to care for specific needs.
- **Scalability**: Organizations can scale these components independently to optimize performance and resource allocation.


**Legacy modernization approach**
[Legacy modernization](https://resources.mia-platform.eu/en/white-paper-legacy-modernization-from-on-premise-to-scalable-cloud-architecture) involves replacing outdated systems and traditional workflows with modern technologies. This approach can leverage existing PBCs to replace and upgrade functionality within a more extensive legacy system.

**System enhancement approach**
Organizations use this approach to enhance existing systems by incorporating PBCs. This approach promotes reusability and efficiency in the following ways.

- **Maximizing investments**: With PBCs, organizations can extend the value of their existing systems to fulfill new requirements, minimizing the need for extensive redevelopment.
