1.0 Introduction

This article presents a retail business architecture and a technical reference architecture suited for large, medium retail chains as well as adaptable to smaller retailers. The architectures are based on an analysis of the projected retail landscape influenced by changing customer behaviors, evolving stores, omnichannel experiences, and demands for same-day delivery of consumers. With the light of market knowledge, we identify the retail enterprise’s business objectives towards transformation and present it as business architecture, along with an existing application landscape. In the discussion, we articulate the key technology success factors for making this business architecture a reality. Thereafter, we propose a retail reference architecture that is useful to transform the retail business to a future-proof business through digital transformation.

Irrespective of whether you are a large retail chain like Walmart, The Home Depot, Walgreens, Marks & Spencer, Carrefour, a medium-chain or a mom-and-pop retail store in the locality, all retailers are equally challenged by shifts in consumer behavior, growth of personal computing devices, developments in technology and other changes in the past few decades. As new technologies grow, we explore the impacts of these shifts on the retail industry to identify how a retailer needs to transform its business.

2.1 Physical Stores to Online Channels

The retail industry went through an apocalypse in the past decade when over 12,000 physical stores across many retailers closed down in North America owing to factors like over-expansion of malls, rising rents, bankruptcies, low quarterly profits outside holiday binge spending, delayed effects of the great recession, and shifts in spending habits. However, previous statistics show that retail spending is increasing year on year. So where are all the sales happening if not at stores? Due to the increasing usage of internet connectivity and its penetration, online shopping has been a major driver for the retail industry. The Global Consumer Insights Survey 2019 shows that almost a third of consumers buy products online weekly or more frequently, up by 5% year-on-year (refer figure 1). As a result, consumer shopping habits have largely shifted from physical stores to digital channels like e-commerce websites and mobile apps.

Figure 1: Frequency of online shopping (Global Consumer Insights Survey 2019)

Further, actual numbers in the predicted environment show a growing number of mobile computing devices, smartphones, and mobile payments driving consumer spending in retail. More often, today’s consumers shop on smartphones than on personal computers. As a result, online retail industry alone has been valued at USD 23,460 billion in 2017 and is expected to register a CAGR of 5.3% during the forecast period (2018-2023), to reach USD 31,880.8 billion by 2023.

2.2 Omnichannel Experiences

Today consumers are not only using one channel to shop, they are engaged with retailers through several touchpoints. Hence, omnichannel experiences are on the rise; in 2016, compared to 7% of online-only buyers, the remaining majority or 73% of shoppers said they use multiple channels during their shopping journey. Interestingly, these shoppers spent more time shopping, spent more money than online shoppers, and were also known to be more loyal. Walgreens mobile retail app is popular amongst its consumers in the United States for the omnichannel experience it provides across all interfaces. The app allows users to manage pharmacy prescriptions, fill out rapid refill requests, and find deals on products in stores. Further, customers can place orders online or via the app that they can pick up at the nearest location. Overall, it complements the in-store experience. This requires the customer to be connected with the mobile app to sales fulfillment operation, inventory, available promotions from suppliers, and more information equally offered within the store. Having an isolated customer database or gamut of disparate systems will not help, rather these systems need to work together to provide the omnichannel experience.

2.3 Evolving Stores

With more stores closing down in 2019, new formats of stores are opening up in many regions. For instance, AmazonGO presents a new format of self-service and sensor-based stores where customers can purchase groceries and checkout without staff intervention. Traditional stores have adopted this concept to a certain extent by introducing self-checkout machines and kiosks which are less automated. However, more vendors like Grabango and Zippin are promoting the hybrid store concept by integrating the store with digital components. With checkout-free experiences through sensor-based communication and innovative apps, customers feel they have more independence during shopping and no queues at the checkout. Technology has been at the forefront of these store transformations and it will prove to be more useful in the future as countries uptake contactless approaches.

2.4 Same-Day Delivery

Delivery is an essential component of online retail. Business-to-consumer (B2C) retail delivery has evolved over the years from a few days to one-day and now same-day delivery with the rise of e-commerce in domestic markets. Retailers like Amazon and Walmart have excelled in this area but speed has always come with a premium price.

In the long run, parcel logistics providers will be able to operate at the lowest cost while offering integrated logistics solutions ranging from orders through fulfillment to delivery and return. There are options like ‘Dropoff’ and ‘Uber’ that have leveraged their resources to offer an innovative delivery experience to customers. The opportunities ahead are huge. Logistics providers need to position themselves for the upcoming transformation and adapt their existing networks accordingly. However, McKinsey states that companies need to build the necessary network to make this possible, and technology plays a vital role in it. One of the four key success factors for same-day delivery is to have fast, integrated information technology systems. They must enable:

2.5 Unexpected Situations

The Covid-19 pandemic has caused a massive surge of grocery sales due to short-term panic buying, and has increased people’s spending towards essential goods via e-commerce, mobile commerce, order online and pick up, and adopting other queue-less methods. Amidst the crisis, going digital has proven to be one of the critical success factors for business continuity of all retailers. Brands and stores that had embraced the digital revolution were best prepared and have thrived, but some have experienced limitations in scaling to unexpected customer demand.

Several small and medium retailers operating on agile practices quickly adapted and transformed their businesses to go online and serve customers. Smaller, brick-and-mortar retail stores in the locality have either adapted using instant messaging services like Whatsapp and Viber or have remained closed for business. Improvised mechanisms are seen in all parts of the world irrespective of the state of their developed or underdeveloped economies.

2.6 Other Concerns

In research done by Accenture, the impacts of pervasiveness, personalization, and privacy were seen to be key challenges to C-suite in the era of retail. Converging industries and complex customer expectations call for retailers to build on each era from Scientific Retail, Customer-Centric Retail, and now Seamless Retail (Figure 2). As customer needs and expectations continue to evolve, retailers must establish nimble, flexible, agile organizations. They must become adaptive.

Figure 2: Converging Industries and Customer Expectations of Retail (Accenture, 2019)

These three aspects call for careful consideration and design of customer identity and personal information management. Given the regulatory requirements in several countries having a compliant technology solution in place is important to retailers.

In summary, as consumers get influenced by technology, retailers are going to be challenged in four key areas of change in consumer behaviors, demand for omnichannel experiences, faster delivery, and changing stores. Also, the sudden need for safer shopping in times like Covid-19 strengthens the case for digital presence. However, most retailers haven’t been able to upkeep with the online demand and delivery or be able to adapt to changing circumstances, as fast as the market has required. Further, a new segment has emerged for contactless payment and delivery in retail. However, pandemic circumstances won’t last for long, but it has given rise to a new normal, and it is a reminder of how resilient and responsive you are as a business. As customer expectations continue to shift, retailers must establish agile and adaptive enterprises. A strong digital foundation has been one of the critical success factors in this context. As a result, we collate the challenges and potential business objectives for retailers and propose a business architecture in the next section.

3.0 The Business of Retail

3.1 Business Architecture for Retail

Each retail enterprise is different from a business perspective; in the simplest instance, Walmart competes in the market on the lowest price strategy and appeals to mass markets. The rest of the business’ strategic and tactical initiatives, teams, and operations are organized to generate this value across all activities in the value chain. Of course, today’s retail enterprises are a step ahead and have business systems in places like point-of-sale systems, inventory systems, sourcing, and human resource management systems to automate routine, manual tasks and speed up processing, for creating this value.

However, business strategies and technologies evolve. Hence, it is important to capture the key value drivers of the overall business operation to ensure technology aligns to achieve this value. We capture this value through a business architecture that acts as the primary business design blueprint that feeds into the technology decisions of the technical architecture.

Figure 3 presents the business architecture for a typical retail chain, particularly with several stores. This mainly highlights the business objectives of the retail chain and how value is derived out of each business component and process involved in achieving these objectives.

Table 1 highlights the objectives for a retail chain, which are common to most retailers. At this point, we keep it at a high-level as architectures are abstract.

3.2 Application Landscape of Retail

Figure 4 depicts one of the possible application landscapes for a typical large/ medium retail chain. To make this retail store possible, different retail components like point-of-sale systems, inventory management, warehousing, sourcing, and in-store devices have to work together. However, it is not currently designed to achieve the business architecture or objectives set out in section 3.1 above as there are several challenges. For instance, the systems may have been acquired at different points in time, and may not be connected to achieve the desired objectives.

Figure 4: Application Architecture of a Retail Chain

Legend to Figure 4:

The common problem with these types of application architectures is that systems are from various vendors that adopt heterogeneous technologies and standards. Retailers must connect them to solve certain challenges like offering seamless omnichannel experiences and opening up new online revenue options. Sometimes, the applications are designed to work in isolation and it results in data silos. The underlying connective technology plays a significant role in achieving the objectives through business architecture. We use this opportunity and challenges as the basis for proposing the desired technical architecture for a retail chain in the next section.

4.0 Technical Architecture for Retail

The value of digital connectivity has become more and more evident in modern times with a lot of people using their mobile phones, tabs, and computers to do absolutely everything possible through that medium. Retail shopping is one of the most popular applications of digital connectivity. With the Covid-19 pandemic which started late 2019/early 2020 and caused 70% of the world population to be in lockdown status for weeks if not months, this digital connectivity is becoming far more critical to carry out the daily activities.

Technology has come to the forefront to rescue mankind from extinction and help millions of people to survive at this trying time. But the retail industry has been utilizing the technology for a considerable amount of time and the companies who were ahead of the curve in terms of technology utilization were the first to respond to the current situation successfully.

As we have seen in the previous section under the business architecture, it is evident that retail stores similar to any other enterprise system consist of various systems built by different vendors utilizing different standards and protocols. The very first challenge of building a technical architecture for a retail store is to identify these various systems and integrate them seamlessly so that they can operate efficiently and coherently. Once these integrations are made, the data residing in these systems need to be exposed in a standard form so that other components of the platform can make use of it. While exposing this data to other systems, it is essential to protect that data from unauthorized access and have proper controls over the access levels.

If you are a large organization with 100s or 1000s of retail stores, this same type of architecture needs to be replicated easily. In the meantime, there should be a centralized or localized control center which is responsible for;

The technical architecture can be divided into 2 main components.

Let’s take a look at the technical architecture which we can derive for the retail industry based on the points we have discussed in this article so far.

Figure 5: Technical reference architecture for retail chain

The technical architecture shown in the above figure 5 depicts the main technical systems, different types of users, interactions of users, and systems. It is an extension of figure 3 where we depicted the business level connectivity amongst these components.

Let’s take a detailed look at the components within the above technical architecture.

4.1 Retail Store

Every retail store is different in size, capacity, resources, location, and accessibility. But at a technical architecture level, we can generalize the components so that every store needs to have at least the following set of components.

The systems mentioned above need to be interconnected internally and externally to offer a seamless, powerful, personalized experience to the users spanning from customers, partners, and internal employees. This is the functionality provided by a comprehensive middleware platform.

This architecture can be repeated across retail stores with minor modifications. But it is extensible enough to support various systems and capabilities required by specific stores.

4.2 Main Control Center/Regional Control Center

Traditional in-store sales, pickup sales, and regional delivery can be achieved through the retail stores which are located in a certain area. But providing the services to a wider geographic area needs a central control center or regional control center which can offer these services to consumers with a much better focus. In addition to that, there should be a centralized control over the retail stores to drive the business properly into larger goals while individual stores achieving their own goals. This main control center also consists of the same set of internal systems (with few more) which are mentioned above in the retail store’s section. But this control center does not have a physical store where people can come and do their shopping. Rather it acts as a point of control for all the other retail stores as well as the main store for online sales. Here are the main middleware components and their functionalities used when deployed in the control center.

This control center deployment can be a scalable deployment spanning across multiple data centers for high availability and better user experience.

Figure 6: Software reference architecture for retail

The technical architecture presented in the previous section is designed in such a way that it can be implemented with a variety of software vendors available in the market. Let’s select a few vendors in the market and design a reference software architecture so that readers of this article can correlate each product into their respective counterparts more clearly. Open-source technology vendors provide the flexibility and the freedom to design and implement this sort of architecture without much trouble.

The above figure depicts a reference software architecture implemented using open-source software products. These products were selected based on their capabilities and the flexibility they possess through their open source licensing model. Here are the main components used in the above figure.

Apache FTP Server as the File Server — Processing file transfers between the retail stores and the control center is a crucial but asynchronous (or batch) operation that needs to be handled in the background. Details like sales reports, inventory details, API analytics can be shared through flat files and processed later at the control center. Apache FTP server is an open-source file server that can support the required capabilities.

The above software components were selected as a reference implementation. But this technical architecture is designed in such a way that it is independent of any vendor and none of the vendor-specific concepts are used when coming up with the technical architecture. With this reference software architecture, you can map the related products according to your needs and build your software architecture.

6.0 Key Takeaways

For Large and Medium Retail Chains

The retail industry is on the rise like never before. If you are a large or a medium-sized retail chain, there are many small retail chains gaining momentum in their localities and pose a challenge to your global business. To tackle this challenge, you need to innovate faster and go towards the consumer rather than expecting consumers to reach you. Technology takes you to places where you couldn’t reach before. The consumers can automate their ordering of retail items so that they never need to step into a store or write a long list of grocery items and drive around the cities to complete the list. Instead, retailers like you can build the entire ecosystem to automate the buying process and deliver to the customer’s doorsteps just before he/she runs out of stocks at home. This whitepaper presents the business level details, key stakeholders, industry trends along with a reference technical architecture to build this sort of a platform for your business.

For Retail Technology Solution Providers (System Integrators)

Retail business is one of the most innovative and technology-centric businesses at the moment. The brick-and-mortar stores are long gone and retailers like Amazon, Walmart have made the shopping experience so simple that you just have to press a button to refill your essential items. But the reality is that there are a large number of medium-sized retailers who are yet to concur with the technology landscape and build effective retail businesses to compete with mega-retailers. As technology solution providers for retail, you have to understand the key stakeholders in the wider ecosystem, trends, challenges, and technological architectures which can be used to help these retailers to build effective technology solutions that allow them to innovate and grow their business. This whitepaper provides business intelligence, technical architecture, and trends in the retail industry which can be utilized by people like you to build solutions that are more relevant and effective.

For Small Retailers, Mom-And-Pop Stores, and Similar Businesses

Technology is the weapon that large and medium-sized retailers use to ditch the small retail chains. More often than not, small retailers choose the options of unique products, localized packaging, and easy access to name a few as their competitive advantage over these competitors. But these factors are no longer true and small retailers need to think about utilizing the technology in a broader sense and beat these large players with the technology itself. As we mentioned before, technology allows you to reach places where you could never reach before. And as a small retailer, you have a massive advantage over large retailers as your operation is smaller which is nimble and responsive to market changes. If you are a small retailer, you can build innovative services and offerings to your consumer base using selected technical architecture components presented in this paper. You can utilize the store level technology architecture, to begin with, and scale that out as and when necessary. There are many open source technology vendors available in the market so that you can start utilizing those technologies with a lower cost to build the desired technology platform to innovate and win customers.

For CIO/CTO/Product Management Teams of Retailer/Retail Technology Providers

Innovation is a key aspect of any competitive landscape. To innovate, you should have a solid understanding of the business and the usage of technology within the retail industry. This whitepaper discusses the business level details of the retail industry and the technical reference architecture to build that solid platform to innovate and grow the business. As a business-focused executive, you can use this information to understand how technical components fit into your business to make innovative revenue opportunities like online presence, mobile retail, and hybrid stores possible.
