Chapter 1: Technology and the Modern Enterprise

Having tech knowledge is crucial in just about every sector of business, no matter what kind of job you have. It’s really just an intro chapter telling us that technology and technology based jobs are increasing and highly attractive, as they grow rapidly

Strategic Information Systems
* Defined by the purpose and objective by which they are created * Purpose is to fulfill organizational processing needs
* Improve efficiency and success

4 Components of an Information System
* These are interdependent (changes in 1 component may affect all 4). This is referred to as SYSTEMIC EFFECTS

First order change
* Only effects TECHNICAL subsystem
* This makes it the easiest to evision, justify and manage

Second Order Change
* Effects the People Component
* Increased Informational intensity, new skills and responsibilities, as well as different groups of people involved.

Third Order Change
* Third order change effects organizational structure
* Reporting relationships, changing the organizational structure, incentives / disincentives * Seeks to transform how the organization operates

Chapter 2: Strategy & Technology

Firms strive for a sustainable competitive advantage. How do we achieve this?: * 5 forces (buying power, supplier power, threat of entry, threat of substitutes, barriers) * *****Operational Effectiveness: performing the same tasks better than your rivals perform them************ * Try to prevent Fast Follower Problem – the problem that occurs when tech savvy rivals see what the first mover did, learn from their success and missteps, and produce a similar product at a cheaper cost, or a superior product * However, Operational effectiveness isn’t enough! We also need: * ****Strategic Positioning – Performing different activities than your rivals, or the same activities in a different way********* * Technology can also create Strategic differences – advantages that rivals will struggle to match.

Outbound Logistics – delivering products or services to consumers 4. Marketing and Sales – Customer engagement, price, promotion 5. Support – Service, maintenance, customer support

Secondary Components of Value Chain (FI, HRM, R&D, P):
