Mastering Composable Architecture: A Technical Guide for Retail Success

State-of-the-Art in the Retail Industry: Monoliths and Multichannel

There are two main software problems in the Retail Industry:

Monolithic Architecture

Historically, many companies in the Retail sector have adopted a monolithic architecture, which involves developing and releasing applications as big single units. This approach makes the evolution of applications more complex, with the risk of regressions throughout the system when attempting to improve a specific component. Simultaneously, the complexity of the application grows as its size increases, leading to challenges in managing it effectively.

Key disadvantages of monolithic architectures include:

• Unachievable Evolution: It becomes intricate to evolve a small piece of a large application, risking regressions in other parts.
• Escalating Complexity: The application becomes more complex as it grows, making it harder to manage efficiently.
• Problematic Scalability: Scaling an entire application becomes more challenging and costly.
• Higher Costs: Optimizing costs becomes more complicated.
• Limited Technologies: Introducing new technologies is only sometimes feasible.
• Difficult Distribution: Publishing and distributing bigger applications is more laborious and demanding.

Multichannel

Multichannel describes a business strategy that involves interacting with customers and delivering products, services, and information through multiple channels or platforms. These channels can include physical stores, online websites, mobile applications, social media platforms, telephone, email, chat and message platforms, and other touchpoints where customers interact with a brand.

Multichannel can become very challenging for IT teams due to the complexity of managing and integrating various channels, each with unique requirements and technologies.

Here are some reasons why multichannel can be an obstacle for IT.

• Diverse Technologies: Different channels often operate on diverse technologies, making it challenging for IT teams to integrate and maintain consistency across platforms seamlessly.
• Data Integration: Combining and synchronizing data from various channels can be complex. Inconsistent data formats, structures, or sources may hinder effective data integration.
• System Compatibility: Existing IT systems may not be compatible with the technologies or interfaces of all channels. Ensuring compatibility and smooth interactions can require additional efforts and resources.
• Security Concerns: Managing security across multiple channels poses a significant challenge. Each channel may have different security protocols, and ensuring a consistent and robust security posture becomes crucial.
• User Experience: Maintaining a consistent and positive user experience across different channels is demanding. Users expect seamless transitions and consistent branding.
• Upkeep and Maintenance: Regular maintenance and updates must be conducted across all channels. This can be resource-intensive, especially if each channel requires unique modifications or improvements.
• Scalability Issues: As the number of channels increases, scalability becomes a concern. Ensuring that the IT infrastructure can accommodate growth and increased demand across all channels requires strategic planning.
• Communication Challenges: Ensuring effective communication and coordination among different teams responsible for various channels is crucial. Lack of collaboration can lead to siloed efforts and hinder overall success.
• Rapid Technological Changes: The rapid evolution of technology may necessitate constant adjustments to keep up with new features, security measures, and user expectations across multiple channels.

Typical Issues in Retail Operations

Multichannel and monolith can bring difficulties to Retailers in all their typical and unique assets and operations.

Sales Channels
Retailers often operate through diverse sales channels but frequently lack a unified, standardized approach. This results in disparate workflows and varying data management practices across channels, hindering the adoption of a seamless omnichannel strategy. Consistency in operations impacts efficiency and upholds a uniform customer experience.

Returns Management
Returns management poses challenges for retailers, often needing a unified channel approach. This can inconvenience customers, limit their options for returns, and create operational inefficiencies for retailers due to disparate workflows and data management practices. A standardized returns system enhances customer convenience and optimizes retailer operations.

Warehouse/Logistics
Divergent workflows in sales channels can impact warehouse and reorder management for retailers, creating challenges in centralizing and standardizing warehouse operations. The proliferation of channels makes achieving unified management and a well-organized IT architecture more complex.

Payments and Invoicing
Managing different kinds of payment transactions, invoicing, and reporting among many channels and tools is very hard. If you add third-party channel commerce, you will need ad-hoc invoicing and flows to manage further and control.

Customer Data
Effective customer data management is crucial, especially with the privacy regulations introduced with GDPR. A multichannel approach, with different formats and dedicated flows for specific channels, complicates such data’s maintenance, evolution, and proper management.

Cybersecurity
Without shared standards, best practices, and ready-to-use components to help enforce them, it is often easy for some workflows not to meet all cybersecurity criteria. This can lead to several security risks, including lack of visibility and control, increased attack surface, and a consequent increased risk of data breaches.

What is a composable architecture?

In modern cloud-based systems, Composable Architecture is a software architecture pattern based on building software systems from small, independent components that you can combine.

Within the Composable Architecture, we can identify several key elements:

• Templates: These serve as the starting point for new developments, containing all the best practices and shared implementation within the company/team. They act as accelerators, being reusable and evolving.
• Microservices: These are individual, agnostic, and independent services that perform specific tasks. They can be generic or specific.
• APIs: These are sets of protocols, routines, and tools for building software applications. They provide a way for different software components to interact with each other, allowing them to exchange data and functionalities.
• Packaged Business Capabilities (PBC): These modules, formed by combining multiple services, deliver a set of common business functionalities. These services share the same objective and fulfill a specific business task or functionality.

Examples of PBCs in the Retail industry

• Order management system: The PBC offers a full order management system that supports the connection to a Database for the CRUD operations on the order, throughout different sales channels.
• Partner sales channel management system: The PBC offers APIs to manage third-party channels and their configurations (Amazon, Zalando, etc.).
• Logistics: The PBC helps the management of the warehouse, products, materials, tracking, and distribution to the stores.
• Payment Manager: The PBC for the comprehensive management of customer payments utilizes payment providers supported by the company and provides users with all related functionalities, from the initial payment transaction to refund requests and payment status verification.

Why Is Composable Architecture Becoming More Popular and Important for the Retail Industry?

In the dynamic retail industry, responding quickly and actively to new challenges and opportunities is critical. In addition, the retail sector is undergoing continuous transformations driven by shifting consumer preferences, technological advancements, and evolving market dynamics. To thrive in this fast-paced environment, retailers must embrace agility as a core competency.

• Flexibility and Adaptability: Organizations can easily build systems that are more flexible and adaptable, as they can easily reuse and repurpose existing components.
• Reusability of Components: Companies can improve efficiency and speed up the development process by dividing the system into small and independent components that can be developed and tested separately.
• Improved Efficiency and Development Speed: Organizations can recycle and adapt existing components instead of initiating projects from the ground up.
