Q

How Do Structured Processes Differ from

Dynamic Processes?

A

Structured processes support operational and structured managerial decisions and activities and Standardized, and usually formally defined and documented and exceptions rare and not well tolerated and process structure changes slowly and with organizational agony. Example is customer returns, order entry, purchasing, and payroll. Dynamic supports strategic and less structured managerial decision and activities, less specific, fluid, usually informal, exceptions frequent and expected and adaptive processes that change structure rapidly and readily. Examples are collaboration, social networking, ill-defined, and amgibuous situations.

Q

Islands of Automation (a.k.a.

A

information silos

22
Q

Islands of Automation (a.k.a. information silos)

A

• Information silos are not a problem until processes begin to
use and store data about the same entities (duplicate data).
• Ongoing evaluation and short and long term strategic thinking
is needed…
• If we have information silos, is that an inherent or natural part
of our business, or is it an indication of lack of focus?
(Depends)
– VCs inherently do this and do it well.
– At the same time, some of the worst merger & acquisition
deals of all time were ones where the company was
swinging for the fence

23
Q

How Do Information System Silos Arise? 4 ways

A

– Data isolated in islands of automation
– Different department goals
– Different personal and workgroup needs
– Duplicate data as organization grows

24
Q

Eliminating Duplicated Data

• Two Options:

A

– Eliminate duplicated data is to store a single copy of
the data in a shared database, and revising business
processes and applications to use that database
(enterprise information system)
– Allow the duplication, but to manage it to avoid problems
• Impractical?

25
Q

Emergence of Enterprise Application

Solutions.

A

• Existing business processes were ineffective and
needed to change
– Business process reporting was inherently slow and
inaccurate
• Adopting integrated data and enterprise information
systems promised to significantly improve process
quality over time

26
Q

Altering and designing business processes to take

advantage of new information systems

A

Business Process Reengineering

27
Q

is difficult, slow, expensive,

and require a high level of expertise

A

Business process engineering

28
Q

Proprietary systems are

A 
expensive
– High initial development costs
– High ongoing maintenance costs
• Business needs and industry requirements are constantly
changing
29
Q

create stronger,
faster, more effective linkages in value chains
– No pain, no gain`

A

Integrated data, enterprise systems

30
Q

Emergence of Enterprise Application

Solutions. 4 of them

A
  • Inherent processes

– Based on “industry best practices”

A

Inherent procedures

32
Q

36
Q

• A suite of applications called modules, a database,
and a set of inherent processes
• Consolidates business operations into a single,
consistent, computing platform
• CRM functionality + accounting + manufacturing +

• Suite of software applications integrating existing
systems with layers of software that manage
connections between applications
• Connects system “islands”.
• Enables communicating and sharing data.
• Provides integrated information.
• Provides integrated layer over the top of existing
systems while leaving functional applications “as is”.
• Enables a gradual move to ERP

A

Enterprise Application Integration (EAI)

41
Q

EAI Automatically Makes

A

Data

Conversions Among Different Systems

42
Q

There is no centralized EAI database?

A

True. Instead, EAI software keeps files of metadata that
describe data formats and locations (helps to locate
data)

43
Q

Q5: What Are the Elements of an ERP

System? 5 of them

A

Applications programs, databases, procedures,

training and consulting that integrate: On next question.

44
Q

Q5: What Are the Elements of an ERP
System?
• Applications programs, databases, procedures,
training and consulting that integrate: What 5 things

A 
– Supply chain
– Manufacturing
– CRM
– Human resources
– Accounting
45
Q

– Set configuration parameters
– Choose and ERP solution close to organization requirements
or defeats the purpose of ERP (build vs. buy)

A

• ERP application programs

46
Q

ERP databases

– Initial database design included (2 things)

A

• Trigger program code (do something automatically when certain
conditions arise) – (Security Alert: Watch system permissions –
Trojan or SQL Injections)
• Stored procedure code (enforces business rules – discounts)

47
Q

What Companies Are the Major ERP

Vendors?

A

Epicor, Microsoft Dynamics, Infor, Oracle, SAP

48
Q

Q6: What Are the Challenges When
Implementing New Enterprise Systems?
• Four Primary Factors

A

– Collaborative management
• No single boss (steering committee recommended)
– Requirements vs. capability gaps
• Change organization vs. change system dilemma
– Transition problems
• Isolated systems to unified system
– Employee resistance due to threats to self-efficacy
(sense of being able to accomplish one’s job)

49
Q

• Software design philosophy
• Activities are organized into modules of functionality
called web services
• Web services are requested and delivered over the
internet using SOA standards
• Service providers create “service descriptions” that
help developers know how to interact with web
services
• Service descriptions are published using Web
Service Description Language (WSDL)
• Web services delivered via XML, SOAP, REST, et al.
• Used by SAP, Oracle ERP

A

What Is Service-oriented Architecture

(SOA)?

50
Q

What Is Service-oriented Architecture
(SOA)?
• The Pizza Stand

A 
– Pizza ordered by
customer
– Delivery occurs in
accordance with the
terms of the menu
– Production of the pizza is
encapsulated or hidden
from the user
51
Q

Why is SOA important for Enterprise

Systems?

A

• Many ERP applications developed before the internet
• Re-writing source code to be mobile device and
internet friendly is expensive and in many cases
infeasible
• SOA can allow access to popular functions and
features via web and mobile
