System Components: software enhancements and algorithms
System Components: firmware functionality

Technology Benchmarks
Competitive advantage. CRM-Customization-Personalization-RISN-BTO
Improved Productivity.
Enhanced Profitability.

Comp Advantage
“profitable and sustainable position against competitive forces
Evolutionary Cycle: Price-> Quality-> Service-> Customization
Forms of Comp Adv.
Low Cost Advantage
Price Advnatage
Quality Advantage
Service Advantage…….

Improved Productivity … we look for
Transactions per hour
Process integration
Work flow processing
Control flow
Resource scheduling
Inventory control
Space management

Safeware-how to keep running system continuously well
Peopleware- train people to use software correctly to get the main benefits (control)
Netware: all devices can comm. With each other
Underware: physical characteristics of technology

Input/output Unites
K: Keyboard
I: Impulse  External Storage Device
P: Printed 
V: Verbal
G: Gesture Info Flow ^ v ^  Central Processing Unity  ^ Control Flow Control Flow
Higher the speed, the faster access
External Storage Device
SEQ: Magnetic Tape
Volatile Electivity to maintain contents
NON-Volatile: no electricity to maintain contents
Hard Drive
Flash Drive
Zip Drive
DVD Drive

Central Processing Unit
CU- Online / Offline
OS- Firmware
ALU- co-processor. (math)
ROM- syntax /mfg role. Read only memory (limits functionality of the system).

System Jargon
Sequential Access: Tape
Sequential Access: Record
Random Access: CD
Stereo System: Plug
Computer System: Port :location to connect to devices
Network System: Node

Peripheral Devices
Port: physical device connection
Parallel- 8 bit transmission
Serial- single bit transmission
USB- universal serial bus
ECP- extended capabilities port
IRDA- infrared device accessibility
Wireless- no physical connectivity
MDB- multi-drop bus connectivity
Node- network device connection
Pnp- plug and play auto-configuration

Bus Structure
Bus- electric circuitry for power, data, and other signals
Bus Architecture
Data Bus- controls transportation of data
Address Bus- directs operations/secures data
Control Bus- governs the processing of data (what to do when we find it)

Multiprocessor Inferfacing (connecting 2 devices together)
The 5 C’s
Confidence: Test each system separately
Contracts: analyze existing provisions
Communications: what, how and when sent
Comparisons: identify installed users
Contingencies: Place downtime strategies if interface is not working
System Designs
System Products
Vendor Designed
Types of Systems
In house – on property
Shared – some components on your premise, some on another (wide area network)
Off Premises:

System Boot (every time start system)
Diagnostics- system gives you message ?
Maintenance: tell you to compress files, make room
Operating System
Application Software
Program Design
Generic Software- can use in any industry ( word, excel, pp)
Industry Software-
Integrated – best
Non Integrated

Programming Protocol
Compiler- takes entire program as input
Interpreter- takes single…

Source-Object Code
Source Code  Compiler  Object Code
Source: Human readable programming (Spoken Language) Non-proprietary
Flowcharts Depict : easy way of seeing the detail
Information Flow
Documentation Flow
Communication Flow

Software Design: Payroll Management
Output Process Input
Payroll Checks
