• Introduction
•Re-design Process
•The Purpose of Process Redesign
•Re-Design Heuristics
Agenda
Where We Are
• Complex structures: • not transparant: badly controllable, fault intolerant
• System proliferation:• overlap, difficult information exchange, uncomfortable, bad
maintainability,
• Inflexible structure:• change = pulling a house of cards
Process perhaps designed once, but organic evolution for years...
Introduction: Existing processes
•What is (re)design?• Narrow scope: adaptation of process
• Business Process Redesign, Business Process Reengineering, Business Process Improvement, etc.
• “fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical measures of performance” (Hammer and Champy, 1993)
• Organize before automation Process thinking
•Existing organization, “sick” workflow: redesign
•New organization, no workflow: design
(Re)design of processes
The distinction between design and redesign

The Purpose of Process Redesign
•Purpose: Identify possibilities for improving the design of a process: “as is” “to be”
•No silver-bullet: requires creativity
•Redesign heuristics can be used to generate ideas
Descriprive modelling
of the real world (as-is)
Prescriptive modelling
of the real world (to-be)

(T+/-,Q+/-,C+/-,F+/-)
Design criterion 1: Time
•Cycle time, including• service time (including set-up)• transport time (can often be reduced)• waiting time
• Due to resource contention (limited capacity)
• Due to external communication (waiting for client/partner)
•Several ways to improve time properties:• Improve average• Improve variance
• Increase ability to meet due dates• Increase perception of wait time
•Product•Product meets specifications and/or expectations
•Process, e.g.•Promises made to customers and (reasonable)
customer expectations are met•Data and documents are handled correctly•Decisions made in the process are correct•Correct & timely information is provided to the
customer
Design criterion 2: Quality
•Type of costs• fixed or variable•per time unit, per use (consumable resources)•processing, management, or support.•human, system (hardware/software), or external,
Design criterion 3: Cost
•Ability to react to changes.
•Flexibility of• resources (ability to execute many tasks/new tasks)•process (ability to handle various cases and changing
workloads)•management (ability to change rules/allocation)•organization (ability to change the structure and
responsiveness to demands of market or business partners
Design Criterion 4: Flexibility
Re-Design Heuristics
1. Task elimination
2. Case Assignment
3. Parralelism
4. Task Composition
5. Flexible Assignment
6. Outsourcing
7. Task Automation
8. Integration
• Sometimes "checks" may be skipped: trade-off between the cost of the check and the cost of not doing the check.
Task Elimination
•Other tasks to consider for elimination:•Print•Copy•Archive•Store•More generally: non-value adding activities
•Task elimination can be achieved by delegating authority, e.g.•No need for approval if amount less than Y•Employees have budget for small expenses
Task Elimination (cont.)
(T+,Q-,C+/-)
Case assignment (ASSIGN)
“Let workers perform as many steps as possible for single cases”
•Most extreme form: for each work item the resource is selected that has worked on that case before

(T+/-,Q+, F-)
“Consider whether tasks may be executed in parallel”
Two types of parallelism: semi and real parallelism
Parellelism (PAR)

Task Composition (COMPOS)
“Combine small tasks into composite tasks and divide large tasks into workable smaller parts”
•Combine small tasks into a larger one:• setup reduction, no fragmentation, more commitment•more work to commit, one person needs to be qualified
for both parts

(T+,F-)
Assign resources in such a what that maximal flexibility is preserved in the future”
•For example, assign work item to most specialized resource.
Flexible assignment (FLEX)

“Consider outsourcing a workflow in whole or parts of it”

Task automation (AUTO)

• Lecture:•Redesign is crucial for many organizations•Redesign is never final•Redesign often means that a trade-off must be made•Redesign is difficult
