E-Business

Business View

• which business strategy and infrastructure, Information system strategy and structure
• Main and subprocesses but without details
• In the business view are also all the information about the company (sitze, market, industrie, etc. )
• Most important Information

Process / Organisation View

• This view shows the several processes in detail

Application View

• The several information systems

Technical View

• Devices and Equimpent etc.

• The process view deepens the information regarding the processes and tasks or functions which are relevant in the context of a project.
• The eEPC supports the description of the process view.
• Beside the flow of tasks and functions it should become clear how the information systems represent and support the  processes.

The event - driven process chain (EPC) is a methodology to depict business processes in connection with information systems.

• Processes use functions and data which are provided by information systems.
•  The application view shows how the business logic – in the form of functions and data – can be distributed to several applications.
• The figure “application view” supports the textual description of the application view.

• The application view shows the distribution of the business logic (in the  form  of functions and data) to the involved applications (application software,  application programmes).
• The application  view assigns the involved applications to the involved roles or parties. Links between the applications show access options and integrations.
• Thus, the application view shows the distribution of the most important functions and data to the involved applications. This is useful for the understanding of responsibility areas, dependencies and risks.
• An application is seen as a logical unit in the sense of the operator. The figure shows the application level, the data level and the client level.
• The application view does not show a possible distribution of an application to several technical systems.

• Advantages:
  • Independency
  • Low investment
  • Low complexity
  • All resources on one computer
• Disadvantages:
  • Only one user at a time
  • Isolated system
  • Data exchange only with media break
  • Risk of total failure

• Advantages
  • Several users at a time (but not on the same file)
  • Users can work independently
  • Access to shared resources
  • Mobile devices can be used in the network or autonomously
  • Data exchange is possible
• Disadvantages
  • Data are partly stored locally, partly centrally.
  • The coordination of the users needs rules and agreements.
  • High costs because of autonomous PCs

• Advantages:
  • Several users can work with the same data stock at a time.
  • Users can use other a pplications independently and flexibly because of the PC.
  • Additional users can be connected easily.
• Disadvantages:
  • The system can usually be used only in a network.
  • The costs for installation and maintenance of the distributed system are high.
  • High procurement costs for PCs.

• Advantages:
  • Several users at a time which work with the same data stock
  • All resources on one computer
  • Central system operation
  • Low costs for terminals
• Disadvantages:
  • Integration with other systems is usually difficult and limited
  • Data exchange only via media breaks
  • User has no influence on the system
  • Connection of additional users is limited

Client has to be installed and operated on every end user device. Installing and updating are costly.

The PCs allow the users high degree of freedom with individual settings etc (can be security and faulty issues)

• to reduce the effort needed for the operation of the clients the client component was shifted to a centrally operating terminal.
• Several users possible
• The devices of the end user are stupid and simple input and output is available
• Example Microsoft remote Desktop connection, citrix or metaframe

The complete business logic is at the server software and the user has access via a protected internet connection

Web browsers are extended Rich Internet Applications or special java based clients

• Advantages:
  • The same system and the same data stock available for all users
  • Completely central operation model which enables fast adjustments (no updates or release changes)
  • Low preconditions or barriers for new users
• Disadvantages:
  • Server needs high performance to cover loading peaks
  • High dependence on the availability of the network
  • Reduced degree of freedom with the single users

• Advantages:
  • The same system and the same data stock available for all users
  • No need to care for installation and operation (no updates, back - up, etc .) for the using organisation
  • With customizing, “Do it yourself” is possible
  • Low preconditions or barriers to start
• Disadvantages:
  • High dependence on the system provider
  • High dependence on the availability of the network
  • Data no longer hosted in the own company
  • Definitely limited to the supplied functionality

graphical depictions (darstellungen) for information systems and computer sience are called notations. They allow a clear description of business matters with the help of defined symbols and rules. (here we use uniform notations)

Applications in the area of e - organisation extend the internal and function - specific information systems and IT tools with functionalities which enable cross - functional communication and collaboration.

E - organisation is the support of relationships and processes inside a company using networked information technology (vom Ralf)

• You need to use it in the right way
• You have to feed it with good information
• You also need a  good and nice custormer service

• You already have clear processes and ways how your organisation is working
• It is a good business model needed That can be suportet!

Definition 1: E - commerce is conducting sales oriented business activities (e.g., distribution, selling, marketing, and  servicing of products or services) electronically over computer networks such as the Internet, extranets, and corporate networks

Definition 2: E - commerce is the support of business relationships and processes of a company with its customers using networked information technology. (from Ralf)

Only definition from Ralf: E - procurement is the support of business relationships and processes of a company with its suppliers using networked information technology

Digitalisation is decisive for the economic and social development. The information systems are omnipresent because they are based on mobile and cloud technologies. People and Organisations are also mostly represented digitally.

• Information as a resource (data maintenance is important)
• Good information (non redundant, correct, right time, etc. )as a basis for decision making and to act apropriate
• More interaction everywhere and a shift from push to pull

E - business solutions can provide an on - demand access to information which helps the user to achieve his or her  goals (capability to act)

• Electronic media connect supply and demand (allows decison making for information, products and services)
• matching of supplier and customers or demand and supply (via platfrom)
• Market performance has been newly defined and can be
  • aggressive (focusing on the product price) or
  • defensive (creating hardly comparable products and services).
• customization of products (Pre definded options like mous and keybord for computer or color, weel for car etc. )
• Airbnb, booking.com etc. --> they find for you what you want according to some filters

E - business solutions can intermediate between two or more involved parties by supporting search (e.g. for the market price) or configuration with interactive, automated dialog processes.

• several programs provide information in one system
• virtual companies

E - business solutions can integrate business models and processes of the involved parties by integrating their IT  systems. Several involved parties build a value creation system.

• Which value or benefit will be created for the involved parties?
• Who is the target group?
• Architecture of the value creation?
• How will the company generate earnings with the business model?
• Can partners and employees be motivated?
• is the necessary knowhow available?
• .....

• The involved business partners and their roles (depicted graphically)
• The business model of the operating organisation
• The distribution of tasks among the involved parties (depicted graphically)
• The strategic and operative goals or benefit expectations of the involved partners.

The Figure „Business Scenario“ supports the description of the business view. The figure contains:

• The involved business partners and their roles
• The processes that are relevant in the context of the project and the distribution of the processes among the involved partners (distribution of tasks)
• The exchange relationships between the involved partners that are relevant in the context of the project

• B2C e - commerce sales increase from year to year, while the traditional sales channels stagnate in the most industries.

• If the automated electronic business transactions between companies are included, the B2B e - commerce volume is much larger than the volume of B2C e - commerce.
