”Redesigning Enterprise Processes for e-Business”, Omar A. El Sawy
• BPR: • ’a performance improvement philosophy that
aims to achieve quantum improvements by primarily rethinking and redesigning the way businesses are carried out’
• Business Processes: a set of activities that transform a set of inputs into a set of outputs

Enterprise Resource Planning
• ERP is a software solution, with all the organisation’s records managed from one large database. An integrated IS.
• It takes the process view of an organisation to meet the organisational goals tightly integrating all functions of an enterprise.

Relationship BPR - ERP
• A BPR study• brings out deficiencies of the existing system• attempts to maximize productivity through
• re-structuring and • re-organising the human resources as well as the
divisions and departments in the organisation
• BPR will initially question the value-add of the particular process
• Then it will go on to put some systems and procedures in place -> ERP is a key enabler in any BPR effort

Relationship BPR – ERP (2)
• You can• do BPR without buying an ERP solution,
• unusual
• buy an ERP solution without doing any BPR• wasteful investment...
• The question is not whether ERP functions or not without BPR
• Key question: whether every company that implements ERP has to reengineer its processes

ERP
• ERP doesn’t blindy automate- it takes into account• company’s internal issues,
• but also factors in the external imperatives in terms of competition, time-to-market,...

IPOM approach
• New managerial approaches• Concurrent Engineering:
• an integrated, dynamic approach to new product development. New product development teams composed of experts from different functions. Share the same goals.
• Group Technology: • focused “cells” specialising in a small number of
similar products.

IPOM approach (2)
• Development of IS:• MRP- Material Requirement Planning
• not good enough on its own...
• Integration of modern DBMS, DSS and MIS • -> the new generation of ERP systems was
borned
• An essential process- The order fulfilment • -> Integrated Production and Order Management
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 20

IPOM approach (3)• Process-based
• Process: order fulfilment- from the reception of a customer order to the supply of the right goods on time, the required quantities and at a competitive cost
• ERP supported• 3 types of IS support Order fulfilment process:
• Transaction Processing System (any transaction can be ordered/analysed via the software)
• MIS (a unique database)• DSS (decisions’ consequences can be analysed, ...)

IPOM (4)
• An Integrated IS• finance, marketing, production, purchasing
• that supports order fulfilment process:• Transaction processing systems / MIS / DSS
• A single DB• A model base (for well-structured/routine
processes, for non-structured/-routine problems, or for process control)

Production and order policies
• Process triggered by customer orders• Written form, long term contract, order issued
by marketing based on a demand forecast
• Orders entered into Master Production Schedule
• Competition in order fulfillment process:• time, cost, flexibility, and quality
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 24
University of

Production and order policies (2)
• Inventories of finished goods are used to buffer against uncertainty (in forecasting)
• Several alternatives to initiate purchasing orders and production orders:• based on firm customer orders
• based on demand forecasts (+raw mat. inv.)
• based on firm customer orders + current inv. level of raw materials and parts
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 25

Production and order policies (3)
• Importance of lead-time• time from order to delivery
• “Supermarket approach”• if acceptable lead-time > actual lead-time;
no inventory– reduce setup times and batch sizes
• if acceptable lead-time < actual lead-time; keep enough inventory to cover for the difference
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 26
University of

Three types of order policies• Make to stock
• new production triggered by forecasts
• Minimizes the promised lead-time at the cost of carrying inventories
• Make to order• No stocks carried
• Only customer order triggers production
• Assemble to order• Raw materials and parts stocked but final assembly triggered by
customer order

Master Production Schedule (MPS)
• Statement of planned future, gross requirements of end products
• MPS triggered by the market demand• combination of orders and forecasts
• If order fulfillment process not well integrated conflict highly likely:• marketing, production/purchasing
• different measures of performance
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 28
University of

Master Production Schedule
• To avoid conflict:• common set of goals
• Appropriate performance measures
• Management of MPS:• introduction of new requirements
• updating existing requirements
• monitoring and control of actual performance compared to goals

Lead-time and time based competition
• Importance of time in order fulfillment• shorter lead-time
• competitiveness and ability to get new business
• delivery on right time
• promised vs. actual lead-time
• Lead-time:• data processing, decision making, production
• Each operation affects lead-time• should be studied and optimized
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 30

Optimization of operations
• Elimination of unnecessary operations
• Minimization of the duration of necessary operations
• Minimization of delays before, after, and during the operations• batch production --> reduce setup times
• get rid of bottlenecks (DBR)
• information sequentially - hierarchy levels
• control points --> data sharing

Cost considerations -cost based competition
• Profit = selling - buying price
• Higher profit: reduce the cost of products
• Problem of measuring costs of a unit• direct, indirect costs
• fixed, variable costs
• Solution:• Look at the throughput

Job Shop:Implementing Priority Rules (2)
• Machines performing the same function grouped
• Scheduling objectives:• on time completion of each part according to MPS
• the completion of all jobs as early as possible
• minimization of the time that parts spend in the shop (min. process inventory)
• maximization of the utilization of resources by minimizing their idle time
• minimization of costs by using less expensive materials

Job Shop:Implementing Priority Rules (3)
• When setup time is significant and machine capacity limited --> batch processing
• Several models exist to provide optimum• only for very small problems
• based local view of a larger situation
• How to assign priority (simple methods):• FIFO (First In First Out)
• EDD (Early Due Date)
• Current job (to save setup time)
• SPT (Shortest Processing Time)

Job Shop:Implementing Priority Rules (4)
• How to assign priority (complex methods):• Critical ratio (CR)
• difference between due date and current date divided by time required to complete the remaining work.
• Slack Time Remaining (STR)• difference between the time remaining before the due date and
the time required for processing the remaining jobs.
• Slack Time Remaining per Operation (STR/OP)• average slack time per remaining operation.
• Smaller values have higher priority (for the 3 methods)

Job Shop:Implementing Priority Rules (6)
• The selection of most appropriate priority rule as well as decision to expedite a job, is based on the Shop floor control system• current information on the jobs waiting for processing
in front of each machine
• Priority rules based on single machine• starvation --> monitor continuously inventory levels in
front of each machine
• control by input-output analysis• identify bottlenecks

The Just In Time (JIT) Approach
• Founder Dr. Ohno of Toyota, Japan
• Profit = revenue - costs
• to increase profit:• increase revenue
• reduce costs
• Focus on cost (waste) reduction
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 59
University of
Jyväskylä
University of
Jyväskylä
JIT Approach (2)
• Potential forms of waste according to JIT• Quality related waste
• Inventory related waste
• Waste of space
• Material handling waste
• Distinction between value-added and non value-added operations• eliminate (if not possible minimize) non value-
added operations, such as material handling
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 60
University of

JIT Approach (3)• Impacts of JIT in scheduling
• minimize process inventories• use small batch size (ideal batch size 1)
• promote faster setups
• use of scheduling systems
• limit space available for inventories in process
• preventive maintenance efforts
• quality at the source
• long term, close relationships with suppliers to ensure quality and delivery when needed
By: Anicet Y., Maria-J. E., Seppo S., Department of Grouptechnology, Faculty of IT 61
University of

JIT Approach (4)• To succeed in the elimination of waste while
keeping the competitive edge in time based competition, the order fulfillment process in the JIT system is synchronized and controlled by a special system• KANBAN cards
• Contains information: production order, purchase order, inventory control device
• Integrated (all work centers are connected)
• Dynamic (inventories limited by # of Kanbans)

JIT Approach (5)
• Just in time is a form of synchronous production• a system in which entire order fulfillment process
is synchronized (i.e. works in harmony) to achieve its multidimensional goals (time, cost, flexibility, and quality)
• The synchronizing device - the Kanban card provides tight connection between the work centers

The Dynamic Shop:Expediting and Changing Priorities
• Demand fluctuates over time, solutions:• manufacturing to stock
• buffer inventories
• freeze MPS (master production schedule)• stabilize demand over the freeze period
• monitor each job as it moves• ERP systems: analyze data and support decision making
• focus on problematic work centers• derive the schedule according to bottlenecks

The Drum, Buffer, Rope (DBR)Approach
• In this scheduling technique the schedule of all work centers is driven by the schedule of critical work centers (insufficient capacity)
• Three performance measures:• MAX: Throughput (T) = Sales - Expenses
• MIN: Inventory (I)
• MIN: Operating expenses (OE)• avoid production to stock

Material Requirement Planning (MRP)
• Is an early attempt to develop an integrated MIS for the order fulfilment process• By combining information on the demand for products purchased
by the customers with information on the structure of these products,the required quantities of dependent demand item do not have to be forecasted-they can be calculated.Uncertainty associated with forecasting is reduced
• By integrating the inventory management information into the system the requirements for dependent demand items as well as those for independent demand item can be placed against existing inventories and pipeline inventories so that only the net required can be ordered

MRP (2)
• By introducing lead time information for purchased items and for manufactured items manufacturing and purchasing orders can be time phased to ensure delivery exactly when needed
• The original MRP System (MRP I ) combined• Marketing information in the Master Production
• Technological information about the structure of each product and its manufacturing process
• New capabilities were added to these systems including:• Planning module that reveal capacity shortage
• Shop floor control modules that utilise limited capacity efficiently
• MRP II (Manufacturing resource Planning).Systems that deal with resource capacities were born

The typical data file (2)
• Many MRP installations did not fulfil the expectations improve the order fulfilment process. There are several reasons for the failure of MRP System:• Quality of input data

The typical data file (3)
• The important data files in the early MRP applications were the following:• The Master Production Schedule (MPS)- The MPS is
the anticipated build schedule for selected (independent demand) items by quantity per planning period
• Marketing information on actual customer orders and forecasts of future demand.
• Manufacturing information on the current load on the shop floor and the ability to supply additional customers orders during each period in the planning horizon

The typical data file (5)
• The time frame used for the MPS is important.The minimum planning time period known as time buckets specifies the accuracy of the planning process, a time bucket of one week is typical • The minimum length of the planning horizon should be
equal to the total time required to purchase raw materials and component parts, to manufacture and assemble the independent demand item with the longest lead time, to provide enough time for the order fufilment process to supply this item when needed

• Key issue´s to consider are who should mange the MPS and How• The Bill of Material-The Bill of Material or BOM is the
source of information about the structure of each independent demand item. Through the BOM it is possible to coordinate the requirements for subassemblies, components and raw materials
• The Inventory Record-To function properly, the MRP system compares the gross requirements for each part number to its current inventory.Only if the gross requirements exceed the current inventory an order for that part number should be issued

Gross to net and time phasing: The MRP logic
• MRP systems are designed to support the material management function in the order fulfilment process
• The Basic idea is that the same logic can be used for ordering purchased materials or parts, manufactured components and assembled products
• The MPS is the source of information on gross requirements for independent demand items
• Basic MRP logic makes use of this information as input and translates it into time phased net requirements

Modification of: The MRP logic
• MPS is used as the resource of Gross requirements for independent demand items.
• Basic MRP logic is modified to accomodate special situations. a common modification is in the lot sizing policy
• The Economic Order quantity (EOQ) logic discussed early, is frequently used to calculate this minimum size. The same logic applíes parts when economy to scale is available• Ex: The cost per unit decrease as the order size
increases

Modification of: The MRP logic
• Two types of buffers• Buffer stock- in this case the minimum
inventory level target is set.• Buffer lead time-this method is designed to
protect the system from fluctuations in supply lead-time. It is based on increasing the lead time of part number by a predetermined amount to protect the system against uncertainty in the actual deleivery dates

Capacity considerations• MRP logic of gross to Net and Time Phasing derives the
requirements for material from the MPS
• Early applications of MRP logic focused on material requirements
• To coordinate resource availability with resource requirements, capacity considerations had to be added to the basic MRP system
• One way of doing that is known as Rough cut Capacity Planning (RCCP)
• Another approach is known as Capacity Requirement Planning (CRP)

Capacity considerations: Rough cut Capacity Planning (RCCP)
• Goldratt’s logic is translated into the following step:1. Identity the system’s constraints ( the bottlenecks)-this step can be
based on rough estimates of the load on each resource compared to its available capacity
2. Develop a detailed schedule for the bottlenecks-using simple techniques such as Gantt Chart
3. Derive the schedule for all non-bottleneck resources from the schedule developed for the bottlenecks. Since the non-constrained resources have excess capacity the assumption is that it is possible to schedule these resources to support the schedule of the bottlenecks
4. Repeat the process-Since bottlenecks may change over time as the product mix changes or due to changes in resources capacity, it is necessary to identify the system’s constraints repetitively every and to watch the actual utilisation of the bottleneck to avoid idle time

• Logic based on the output of the MRP-work orders generated by the gross to Net and the Time Phasing logic
• Based on the orders released by MRP logic, the required periodical capacity of each resource is calculated
• The MRP logic that generates work orders takes existing in process inventories into account in its gross to net analysis the capacity requirements are more accurate

Capacity considerations: CRP Vs. RCCP
• Both CRP and RCCP are tools for testing the feasibility of the plans developed by the MIS
• The RCCP test the feasibility of the MPS while the CRP tests the feasibility of the MRP plans

2. Select members based on skill and their potential. not personalities
3. Pay particular attention to first meetings and actions. Initial impressions always mean a great deal.
4. Set some clear rules of behaviour. Rules regarding attendance, discussion confidentiality and contributions are very important and help the team perform its tasks in the early stages
