… idea that business process can be changed / improved

… is the questioning of “why things are done a certain way” and not accepting the answer, “because that’s the way we do it”

Provided training, consulting, and technical support to capture and improve the business processes of the logistics center

Investment: $3.75 Million in total Savings: $2.5 Million per year since 1993 Continuing to use AI0Win, ProSim and WITNESS for

ongoing CPI and BPR efforts

“Just as computer-aided design (CAD) tools have improved the speed and quality of hardware design and manufacture, these computer-aided enterprise engineering tools will enable the quick and precise design, testing, and implementation of business process changes”

BPR Success StoriesBPR Success Stories Johnson Controls, Inc.

A multibillion-dollar service provider (outsourcing agent), needed to redesign their new-hire system.

The previous new-hire process took seven weeks to place a new employee on the job, resulting in long cycle times, poor-quality products, and unhappy customers.

Used AI0Win, ProSim and WITNESS for BPR effort After the redesign of the new-hire process, virtually

eliminating processing errors and reducing system requirements by 90%, the new process took only one day to place a new employee on the job.

Need to improve their Procurement Process. The goal of this project was set to optimize the transfer of

information related to all business transactions by replacing the paper-based system with one that relies on Electronic Data Interchange (EDI).

Used AI0Win/ABC and ProSim/WITNESS for the effort Estimates indicate that for every $1.00 dollar invested with

the new system, $23.00 saved. This project was so successful that it recently won the

“Commander-In-Chief National Award for Project Excellence,” which is awarded to the best project in the Department of Defense.

Changes made:– Single loan generalist– Up-to-date software to support the generalist– The trivial loan requests approved via simple table look-up,

more complicated ones forwarded to experts.

Results: – Turnaround time lowered from 6-14 days to 4 hours– Fewer personnel– Order of magnitude increase in number of deals handled

Risks in BPR/How They can be Mitigated Risks in BPR/How They can be Mitigated

Risks Mitigation

Most BPR efforts don’t address implementation

Too much dependence on in-house personnel to perform BPR

Cost, time, and resource requirements are not accurately established

Implementation Planning begins with Project Definition

Established throughout effort to derive better cost, time, resource requirements

Build in-house (organic) capability to leverage domain expertise; use external BPR expertise for facilitation, training, and focused consulting

1. Process design is a design endeavor

2. It requires a set of skilled people

3. Object design plays a central role

4. Consistency in decomposition and allocation

5. Maintenance of input/output contiguity

6. There will always be failure that must be addressed

7. Processes produce other than just the desired product

8. Design of processes for coordination and management (e.g., resource management)

Simulation Modeling

Page 88: Business Process Reengineering: The Key to Success in a Changing Environment Dursun Delen, Ph.D. Assistant Professor Oklahoma State University.

Delen MSIS 5653 - Advanced Systems Development 89

A method for conducting numerical experiments on a computer, based on mathematical and logical representations of a system, in order to evaluate the structure and behavior of the system over extended periods of time.

System

– facility or process of interest

Model

– an idealization of reality

– developed for a specific purpose

Simulation

– a technique for experimenting with the model over time

– to conduct what-if scenarios without distracting the reality

Discrete Event Simulation– The state of the system changes when an event occurs

(at discrete points in time)

Continuous Simulation– The state of the system changes continuously with

respect to time (differential equations provide the relationships for the rates of change)

Significant randomness in the system – need a mechanism to understand the impact of variability

No confidence in meeting the assumptions underlying formal analytical methods

Contention for shared resources [heavy use of priorities and interruptions]

Significant system complexityDesign of new systems with little data

Real world systems are too complex for current analytical techniques

Estimate performance of existing systems

Experiment with proposed designs

Complete control over experimental conditions

It’s a sampling experimentRequires data collection

and distribution determination

Tough to validateInterpretation can be

difficultOften creates a tendency to

place greater confidence in the results than is justified
