E-commerce, or electronic commerce, is the buying and selling of products or services over the internet. As with any business, the success of an e-commerce venture ultimately depends on the satisfaction of its customers. Therefore, taking a consumer-oriented approach is crucial for the success of an e-commerce business.

e-commerce approach from a Consumer-oriented perspective:

• User-friendly website:

The website should be designed with the customer in mind, with a clear and easy-to-use interface. Navigation should be simple and intuitive, and the website should be optimized for different devices.

• Product information:

Customers should be able to find all the information they need about the products or services on offer, including detailed descriptions, specifications, and pricing.

• Personalization:

E-commerce businesses can use data and analytics to personalize the shopping experience for each customer. For example, by recommending products based on their past purchases or browsing history.

• Customer service:

Providing excellent customer service is essential for building trust and loyalty with customers. E-commerce businesses should provide multiple channels for customer support, such as email, phone, or live chat.

• Secure Payment options:

Customers need to feel secure when making purchases online. E-commerce businesses should offer secure payment options, such as PayPal or credit card payments with SSL encryption.

• Fast and reliable shipping:

Customers expect fast and reliable shipping, with real-time tracking information. E-commerce businesses should have a robust shipping infrastructure in place, with options for expedited shipping if necessary.

• Returns and Refunds:

Customers should have a clear understanding of the return policy, including how to initiate returns and how refunds will be processed. E-commerce businesses should make the process as easy and transparent as possible.

Consumer-oriented approach in e-commerce benefit businesses:

• Increased customer satisfaction:

By prioritizing the needs and preferences of customers, businesses can provide a better shopping experience, leading to increased customer satisfaction.

• Improved brand reputation:

Providing excellent customer service and a seamless shopping experience can help build a positive reputation for the business, leading to increased customer loyalty and word-of-mouth referrals.

• Higher conversion rates:

A user-friendly website, personalized recommendations, and secure payment options can increase the likelihood of customers completing their purchases, leading to higher conversion rates and increased revenue.

• Reduced cart abandonment:

By addressing customer concerns and offering clear return policies, businesses can reduce the number of abandoned carts, leading to increased sales.

• Competitive advantage:

In today’s competitive e-commerce landscape, adopting a consumer-oriented approach can help businesses stand out from their competitors and attract and retain more customers.

Traditional Retailing

Traditional retailing refers to the practice of selling products or services through physical stores, such as department stores, specialty shops, and boutiques. It is a long-established method of commerce that has been around for centuries.

In traditional retailing, customers visit a physical store to browse, try on, or examine products before making a purchase. Retailers stock their stores with inventory based on their target audience and demographic, and employ sales associates to assist customers with their shopping experience. This approach allows customers to have a more personalized and interactive experience with the products and the staff.

Traditional retailing advantages:

• Personalized customer service:

Customers can receive personalized assistance from sales associates, who can provide recommendations, answer questions, and address concerns.

• Tangible experience:

Customers can see, touch, and try on products before making a purchase, allowing them to make a more informed decision.

• Social experience:

Shopping in physical stores can be a social experience, allowing customers to shop with friends or family and enjoy the atmosphere of the store.

• Immediate gratification:

Customers can take the products home with them immediately, rather than having to wait for shipping.

• Brand recognition:

Physical stores can help build brand recognition and loyalty through visual merchandising and customer service.

Traditional Retailing Disadvantages:

• Limited geographic reach:

Physical stores are limited to their local customer base and may not be accessible to customers in other locations.

• Limited operating hours:

Physical stores have fixed operating hours, which may not be convenient for all customers.

• Higher overhead costs:

Physical stores require high overhead costs, such as rent, utilities, and staffing.

• Limited product range:

Physical stores have limited space for inventory and product display, which may restrict the range of products available for customers.

• Competition from e-retailers:

With the rise of e-commerce, traditional retailers face increasing competition from online retailers, who offer convenience and accessibility to customers.

E-Retailing

E-retailing, also known as online retailing or e-commerce, refers to the practice of selling products or services through digital channels, such as websites, mobile apps, social media platforms, or marketplaces. It is a rapidly growing method of commerce that has revolutionized the way people shop.

In e-retailing, customers can browse, select, and purchase products or services online using a computer or mobile device. E-retailers typically maintain an online store where customers can view product information, images, and reviews, and make a purchase using a secure payment system. E-retailers can also leverage technology to offer personalized recommendations, optimize the shopping experience, and provide fast and reliable shipping.

E-retailing Advantages:

• Convenience and accessibility:

Customers can shop from anywhere and at any time, making it more convenient and accessible for busy or remote customers.

• Wide range of products and brands:

E-retailers can offer a wider range of products and brands than physical stores, as they are not limited by physical space.

• Price comparison:

E-retailers can offer price comparison options, allowing customers to easily compare prices across different products and retailers.

• Lower overhead costs:

E-retailing requires lower overhead costs than traditional retailing, as there is no need for physical stores or high staffing levels.

• Global reach:

E-retailers can reach a global customer base, allowing businesses to expand their reach beyond their local area.

e-Retailing Disadvantages:

• Lack of tangible experience:

Customers cannot touch, try on, or examine products before making a purchase, which may lead to uncertainty or dissatisfaction.

• Delayed gratification:

Customers have to wait for shipping or delivery, which may take longer than the immediate gratification of buying in-store.

• Potential for fraud:

E-retailing is susceptible to fraud and security breaches, as sensitive information such as credit card details may be vulnerable to theft.

• Competition from other e-retailers:

With the rise of e-commerce, the competition between e-retailers has intensified, making it challenging for businesses to differentiate themselves.

• Technical issues:

E-retailing relies heavily on technology, which can lead to technical issues such as website crashes or payment processing errors.

Key differences between Traditional Retailing and e-retailing:

• Physical presence:

Traditional retailing requires a physical store presence, while e-retailing can be done entirely online.

• Overhead costs:

Traditional retailing involves high overhead costs, such as rent, utilities, and staffing, while e-retailing requires fewer overhead costs.

• Customer experience:

Traditional retailing offers a more personal and interactive customer experience, while e-retailing provides convenience and accessibility.

• Product range:

E-retailing offers a wider range of products and brands, while traditional retailing has limited space for inventory and product display.

• Geographic reach:

E-retailing allows businesses to reach a global customer base, while traditional retailing is limited to the local customer base.

A Web system architecture is the underlying design and organization of a web-based system, including the technologies, protocols, and components that enable its functionality. The architecture of a web system determines how the different components interact with each other, how data is transmitted, and how the user interface is presented.

Key Components of Web System Architecture:

• Client-Side Components:

These are the components that run on the client-side, which is typically the user’s computer or device. Client-side components include web browsers, scripting languages, and user interface components such as buttons and menus.

• Server-Side Components:

These are the components that run on the server-side, which is typically a remote server or cloud-based system. Server-side components include web servers, application servers, and databases.

• Communication Protocols:

These are the protocols that govern how data is transmitted between the client-side and server-side components. The most common communication protocols used in web system architecture include HTTP, HTTPS, and WebSockets.

• Data Formats:

These are the formats used to represent and transmit data between the client-side and server-side components. Common data formats used in web system architecture include JSON, XML, and CSV.

• APIs:

APIs, or Application Programming Interfaces, are the interfaces that enable communication and data exchange between different components of the web system. APIs provide a standardized way for applications and services to interact with each other.

• Security:

Web system architecture must also include security mechanisms to protect against threats such as hacking, data breaches, and other cyber attacks. Security mechanisms can include encryption, authentication, and access control.

Types of Web System Architecture:

• Client-Server Architecture:

This is the most common type of web system architecture, where the client-side and server-side components are separate entities. The client-side component typically consists of a web browser, while the server-side component includes a web server, application server, and database.

• Single-Page Applications (SPA):

This type of web system architecture is designed to provide a more responsive user interface, where the user interface is loaded once and then updated dynamically without requiring a full page refresh. SPA is typically implemented using JavaScript frameworks such as React and Angular.

• Microservices Architecture:

This architecture is designed to break down a large, monolithic application into smaller, independent services that can be developed and deployed separately. Each microservice is responsible for a specific function or feature, and communication between services is typically done using APIs.

• Progressive Web Apps (PWA):

PWAs are web applications that are designed to provide a native app-like experience on mobile devices. PWAs use a combination of web technologies such as HTML, CSS, and JavaScript, along with features such as offline caching and push notifications.

There is no one answer about what is competitive advantage or one way to measure it, and for the right reason. Nearly everything can be considered as competitive edge, e.g. higher profit margin, greater return on assets, valuable resource such as brand reputation or unique competence in producing jet engines. Every company must have at least one advantage to successfully compete in the market. If a company can’t identify one or just doesn’t possess it, competitors soon outperform it and force the business to leave the market.

There are many ways to achieve the advantage but only two basic types of it: cost or differentiation advantage. A company that is able to achieve superiority in cost or differentiation is able to offer consumers the products at lower costs or with higher degree of differentiation and most importantly, is able to compete with its rivals.

In business, a competitive advantage is the attribute that allows an organization to outperform its competitors. A competitive advantage may include access to natural resources, such as high-grade ores or a low-cost power source, highly skilled labor, geographic location, high entry barriers, and access to new technology.

The following diagram illustrates the basic competitive advantage model-

1. External Changes

(i) Changes in PEST factors

PEST stands for political, economic, socio-cultural and technological factors that affect firm’s external environment. When these factors change many opportunities arise that can be exploited by an organization to achieve superiority over its rivals. For example, new superior machinery, which is manufactured and sold only in South Korea, would result in lower production costs for Korean companies and they would gain cost advantage against competitors in a global environment. Changes in consumer demand, such as trend for eating more healthy food, can be used to gain at least temporary differentiation advantage if a company would opt to sell mainly healthy food products while competitors wouldn’t. For example, Subway and KFC.

If opportunities appear due to changes in external environment why not all companies are able to profit from that? It’s simple, companies have different resources, competences and capabilities and are differently affected by industry or macro environment changes.

(ii) Company’s ability to respond fast to changes

The advantage can also be gained when a company is the first one to exploit the external change. Otherwise, if a company is slow to respond to changes it may never benefit from the arising opportunities.

2. Internal Environment

(i) VRIO resources

A company that possesses VRIO (valuable, rare, hard to imitate and organized) resources has an edge over its competitors due to superiority of such resources. If one company has gained VRIO resource, no other company can acquire it (at least temporarily). The following resources have VRIO attributes:

• Intellectual property (patents, copyrights, trademarks)
• Brand equity
• Culture
• Know-how
• Reputation

(ii) Unique competences

Competence is an ability to perform tasks successfully and is a cluster of related skills, knowledge, capabilities and processes. A company that has developed a competence in producing miniaturized electronics would get at least temporary advantage as other companies would find it very hard to replicate the processes, skills, knowledge and capabilities needed for that competence.

(iii) Innovative capabilities

Most often, a company gains superiority through innovation. Innovative products, processes or new business models provide strong competitive edge due to the first mover advantage. For example, Apple’s introduction of tablets or its business model combining mp3 device and iTunes online music store.

Types of Competitive Advantage

1. Porter has identified 2 basic types of competitive advantage: cost and differentiation advantage.

1. Cost advantage

Porter argued that a company could achieve superior performance by producing similar quality products or services but at lower costs. In this case, company sells products at the same price as competitors but reaps higher profit margins because of lower production costs. The company that tries to achieve cost advantage (like Amazon.com) is pursuing cost leadership strategy. Higher profit margins lead to further price reductions, more investments in process innovation and ultimately greater value for customers.

2. Differentiation advantage

Differentiation advantage is achieved by offering unique products and services and charging premium price for that. Differentiation strategy is used in this situation and company positions itself more on branding, advertising, design, quality and new product development (like Apple Inc. or even Starbucks) rather than efficiency, outsourcing or process innovation. Customers are willing to pay higher price only for unique features and the best quality.

The cost leadership and differentiation strategies are not the only strategies used to gain competitive advantage. Innovation strategy is used to develop new or better products, processes or business models that grant competitive edge over competitors.

Customer-to-Customer (C2C) e-commerce refers to online transactions where individual consumers buy and sell goods or services directly to and from each other through digital platforms.

Electronic commerce, or e-commerce, (e-Commerce) is a type of business model, or segment of a larger business model, that enables a firm or individual to conduct business over an electronic network, typically the internet. Electronic commerce operates in all four of the major market segments: business to business, business to consumer, consumer to consumer, and consumer to business. It can be thought of as a more advanced form of mail-order purchasing through a catalog.

Types of e-Commerce

There are 6 basic types of e-commerce

1. Business-to-Business (B2B)
2. Business-to-Consumer (B2C)
3. Consumer-to-Consumer (C2C)
4. Consumer-to-Business (C2B)
5. Business-to-Administration (B2A)
6. Consumer-to-Administration (C2A)

1. Business-to-Business (B2B)

Business-to-Business (B2B) e-commerce encompasses all electronic transactions of goods or services conducted ​​between companies. Producers and traditional commerce wholesalers typically operate with this type of electronic commerce.

                     

Figure: B2B Communication

2. Business-to-Consumer (B2C)

The Business-to-Consumer type of e-commerce is distinguished by the establishment of electronic business relationships between businesses and final consumers. It corresponds to the retail section of e-commerce, where traditional retail trade normally operates.

These types of relationships can be easier and more dynamic, but also more sporadic or discontinued. This type of commerce has developed greatly, due to the advent of the web, and there are already many virtual stores and malls on the Internet, which sell all kinds of consumer goods, such as computers, software, books, shoes, cars, food, financial products, digital publications, etc.

Figure: B2C Communication

3. Consumer-to-Consumer (C2C)

Consumer-to-Consumer (C2C) type e-commerce encompasses all electronic transactions of goods or services conducted ​​between consumers. Generally, these transactions are conducted through a third party, which provides the online platform where the transactions are actually carried out.

 Figure: C2C Communication

4. Consumer-to-Business (C2B)

In C2B there is a complete reversal of the traditional sense of exchanging goods. This type of e-commerce is very common in crowd sourcing based projects. A large number of individuals make their services or products available for purchase for companies seeking precisely these types of services or products.

Examples of such practices are the sites where designers present several proposals for a company logo and where only one of them is selected and effectively purchased. Another platform that is very common in this type of commerce are the markets that sell royalty-free photographs, images, media and design elements, such as iStockphoto.

Figure: C2B Communication

5. Business-to-Administration (B2A)

This part of e-commerce encompasses all transactions conducted online between companies and public administration. This is an area that involves a large amount and a variety of services, particularly in areas such as fiscal, social security, employment, legal documents and registers, etc. These types of services have increased considerably in recent years with investments made in e-government.

Figure: B2A/C2A Communication

6. Consumer-to-Administration (C2A)

The Consumer-to-Administration model encompasses all electronic transactions conducted between individuals and public administration.

Examples of applications include:

Education: disseminating information, distance learning, etc.

Social Security: through the distribution of information, making payments, etc.

Taxes: filing tax returns, payments, etc.

Health: appointments, information about illnesses, payment of health services, etc.

Both models involving Public Administration (B2A and C2A) are strongly associated to the idea of efficiency and easy usability of the services provided to citizens by the government, with the support of information and communication technologies.

An extranet is a controlled private network that allows access to partners, vendors and suppliers or an authorized set of customers normally to a subset of the information accessible from an organization’s intranet. An extranet is similar to a DMZ in that it provides access to needed services for authorized parties, without granting access to an organization’s entire network. An extranet is a private network organization.

Historically the term was occasionally also used in the sense of two organizations sharing their internal networks over a VPN.

During the late 1990s and early 2000s, several industries started to use the term ‘extranet’ to describe centralized repositories of shared data (and supporting applications) made accessible via the web only to authorized members of particular work groups – for example, geographically dispersed, multi-company project teams. Some applications are offered on a software as a service (SaaS) basis.

Advantage of Extranet

• Exchange large volumes of data using Electronic Data Interchange (EDI)
• Share product catalogs exclusively with trade partners
• Collaborate with other companies on joint development efforts
• Jointly develop and use training programs with other companies
• Provide or access services provided by one company to a group of other companies, such as an online banking application managed by one company on behalf of affiliated banks.

Disadvantage of Extranet

• Extranets can be expensive to implement and maintain within an organization (e.g., hardware, software, employee training costs), if hosted internally rather than by an application service provider.
• Security of extranets can be a concern when hosting valuable or proprietary information.

Issues in Extranet

Apart for advantages there are also some issues associated with extranet. These issues are discussed below:

1. Hosting

Where the extranet pages will be held i.e. who will host the extranet pages. In this context there are two choices:

2. Host it on your own server.

Host it with an Internet Service Provider (ISP) in the same way as web pages.

But hosting extranet pages on your own server requires high bandwidth internet connection which is very costly.

3. Security

Additional firewall security is required if you host extranet pages on your own server which result in a complex security mechanism and increase work load.

4. Accessing Issues

Information cannot be accessed without internet connection. However, information can be accessed in Intranet without internet connection.

5. Decreased Interaction

It decreases the face to face interaction in the business which results in lack of communication among customers, business partners and suppliers.
