Part 4 BOAT Framework Introduction
Table of contents • Introduction • BOAT framework – Business – Organization – Architecture – Technology • Case studies – POSH, TTU, Tra. XP • Conclusions Chapter 4: BOAT Framework - 2
Aspects of e-business scenarios • E-business scenarios are generally complex, as they contain many relevant elements with often complex interrelationships, e. g. : – business goals – organization of business – use of information technology • To obtain a well-structured description of a scenario, we need to describe a scenario from the viewpoints of several aspects Chapter 4: BOAT Framework - 3
Classification and aspect frameworks • A classification framework for e-business scenarios consisting of three dimensions – Geared towards characterizing a scenario as a whole (outside), e. g. , to compare scenarios – Discussed in Chapter 3 • An aspect framework (BOAT) for e-business scenarios consisting of four aspects – Geared towards understanding the ingredients of a scenario (inside), e. g. , to analyze a scenario – Discussed in this chapter Chapter 4: BOAT Framework - 4
BOAT Framework BOAT aspects
Technology abstracted Architecture mapped Organization operationalized Business Identifying BOAT aspects Chapter 4: BOAT Framework - 6
BOAT aspects • Business aspect: describes the business goals of ebusiness – explains existence of a scenario • Organization aspect: describes how organizations are structured and connected to achieve the goals defined in the business aspect • Architecture aspect: covers the conceptual structure of automated information systems used to enable organizations defined in the organization aspect • Technology aspect: describes the technological realization of the systems of which the structure is specified in the architecture aspect Chapter 4: BOAT Framework - 7
BOAT aspect ingredients • Business aspect: access to new markets, reorientation of interaction with customers, leverage of efficiency levels; • Organization aspect: organization structures, business processes, business functions; • Architecture aspect: information system structures between organizations, within organizations. • Technology aspect: software, languages, communication protocols, hardware where relevant.
