25
common workgroup processes
sales and marketing, operations, manufacturing, customer service, human resources, accounting
26
process efficiency
doing things right (ex using fewer resources)
27
process effectiveness
doing the right things (ex meeting strategic goals)
28
how information systems improve process quality
automate activities (ex online reservation system) , assist decision making and control data quality (ensure correct customer info)
29
information silos
isolation of data in separated info systems--> problems = data integrity (when data inconsistent), solution= combine data into one database
30
business process reengineering (BPR)
= activity of altering business processes to take advantage of new IT systems
31
enterprise systems that help manage processes- CRM (customer relationship management)
manages customer interactions
32
enterprise systems that help manage processes- ERP (enterprise resource planning)
integrates all core business processes
33
enterprise systems that help manage processes- EAI (enterprise application integration)
connects existing systems without replacing them, provides integrated information
34
elements of ERP system
hardware, software applications, databases, business procedures, training and consulting (h, sa, d, bp, t, c)
35
ERP applications
integrate supply chain, manufacturing, CRM, human resources, accounting
36
challenges of implementing and upgrading enterprise info systems
collab management (no single authority over system decisions), requirement gaps (software may not fit all organizational needs), transition issues (difficult and require training), employee resistance (fear or lack of confidence in using new systems)
37
outsourcing
hiring external organizations to perform IS services. Cost savings, access to expertise and reduction in management load.
38
international outsourcing
common in india and china because of low labor costs, skilled english speaking workforce
39
outsourcing alternatives and risks
IAAS cloud hosting/ PAAS etc- risks of outsourcing= loss of control, dependency on vendor, hidden costs, security concerns
40
business process and information system
business process not required to use an IS but every IS supports at least one business process
41
BPM (business process management)
manage and improve business processes which are networks of activities and databases and flows
42
properties of processes
roles (collection of activities), resources (pple or software), flow (control flow- order of activities; and data flow- movement of data among activities)
43
repository
collection of something- inventory= physical repository
44
5 phases of SDLC (systems development life cycle)
system definition, requirements analysis, component design, implementation, system maintenance (padim)
45
System definition (SDLC)
define goals, assess feasibility (cost, schedule, technical, organizational), plan project
46
requirements analysis (SDLC)
determine user needs, identify new application features
47
component design (SDLC)
design hardware, software, data and procedures
48
implementation (SDLC)
build and test system; convert to new system
49
system conversion approaches
pilot (implement entire system in limited portion of business); phased (system installed in phases- each piece tested); parallel (complete new and old systems run together- very safe but expensive); plunge (high risk if new system fails, used if new system not vital)
50
system maintenance (SDLC)
fix or enhance the system after development
51
how can scrum overcome problems of SDLC
scrum is agile development method that handles change better than SDLC
52
Scrum roles
product owner (represents the customer); scrum master, team members (5-9)
53
key scrum principles
embrace changes in requirements, deliver working versions, testing and improvement, work in short cycles, daily standup meetings
54
padim, is must have many bs, is cia, ba goal,
yes acronyms
55
ETL
extract, transport, load
56
3 primary activities in BI
APP- acquire, perform, publish
57
big data
velocity, variety, volume
58
5 components of BI system
pple, procedures, hardware, software, data
59
4 implementation
pilot (one department), plunge (do when operation isnt vital), parallel (new and old same time), phased (each piece tested)
60
BPR
changing the structure
61
3 enterprise IS
ERP (core business function) , EAI (connects) , CRM (customers)
62
customer life cycle stages
ASSRC (ass rack)
63
