4Quality As A Competitive Weapon
Actual Performance
Design Specifications
Customer Satisfaction
Quality of Design
Conformance Quality
- Costs of quality (COQ) are costs incurred to
rectify the production of of low-quality product
Pages 656 - 660
5Four categories of COQ
- - Prevention costs (design and process
engineering) - - Appraisal costs (inspection costs)
- - Internal failure costs (spoilage and rework)
- - External failure costs (warranty repair work)
6Methods to Analyze Quality Problems
- Statistical quality control (SQC) or statistical
process control (SPC) employ control charts to
monitor successive observations at regular
intervals of time - Pareto diagrams indicates the frequency of
failures (defects) - Cause-and-Effect diagrams identifies potential
causes of failures or defects such as human error
or component failure
Pages 660 - 662
7Relevant Costs and Benefits of Quality
Improvements
- Relevant costs/revenues are those costs/revenues
that differ across alternatives and therefore
must be considered in deciding which alternative
is the best. - In considering quality improvements the relevant
costs/revenues are those that differ between
quality improvements made and quality
improvements not made. - Consider revenues, fixed costs, and variable
costs, before and after the quality improvements.
8Non-Financial Measures of Quality and Customer
Satisfaction
- Even if a product is defect free and meets
conformance quality, it still must satisfy
customer needs - consider total customer satisfaction including
- features that provide fair value
- delivery when promised
- delivery a defect-free product
- ensure that product will not experience early
failure - ensure that product will not fail excessively in
service
9Non-Financial Measures of Customer Satisfaction,
more examples
- the number of defective units shipped
- number of customer complaints
- customer response time ( differences between
scheduled delivery date and date requested by the
customer - timeliness of delivery
10Financial Measures of Quality
- The cost of quality report
- - focus attention on costs of poor quality
- - useful for comparing different quality
improvement programs and setting priorities - - useful for evaluating tradeoffs among
prevention and failure costs -
11Non-financial Measures of Quality
- The advantages of non-financial measures of
quality - often easy to quantify and understand
- direct attention on physical processes and the
exact problems - immediate short-term feedback on quality
improvement efforts - useful indicators of long-term performance
Pages 666 - 667
12Time As A Competitive Weapon
- Time is a key variable in competition
- Doing things faster helps increase revenues and
decrease costs - Think of time in terms of
- - Customer response time time from order receipt
to delivery of product - - On-Time Performance delivered on scheduled
date
Pages 667 - 672
13Time Driver
- A time driver is any factor where change in the
factor causes a change in the speed of the
activity - - Uncertainty about when the customer will order
is a time driver - - Limited capacity and bottlenecks are also time
drivers - A bottleneck is an operation wherein the work
required approaches or exceeds the available
capacity
14Average Waiting Time
- The average waiting time is the average amount of
time that an order will wait in line before it is
set up and processed.
15Theory of Constraints (TOC), Three Measurements
- 1. Throughput contribution, i.e., sales revenue
minus direct material costs - 2. Investments equal to the sum of material costs
of direct materials inventory, work-in-process
inventory, and finished goods inventory, plus RD
costs, plus costs of equipment and buildings. - 3. Operating costs, equal to all operating costs
(other than direct materials) incurred to earn
throughput contribution including salaries and
wages, rent, utilities, and amortization.
16TOC, the Objective
- Increase throughput contribution while decreasing
investments and operating costs when faced with
some bottlenecks and non-bottleneck operations..
The theory of constraints considers short-run
time horizons and assumes other current operating
costs to be fixed.
17TOC, Steps in Managing Bottlenecks
- 1. Recognize that the bottleneck resource
determines throughput contribution of the plant
as a whole. - 2. Search and find the bottleneck resource by
identifying resources with large quantities of
inventory waiting to be worked on. - 3. Keep the bottleneck operation busy and
subordinate all non-bottleneck resources to the
bottleneck operation. - 4. Take actions to increase bottleneck efficiency
and capacity
18TOC, Focus
- Measuring throughput by the value of production,
and not by physical units.
19TOC Compared to ABC
- Some observers have claimed, incorrectly, that
ABC costing assumes that almost all
organizational costs are variable. This is
incorrect. - In most organizations the only variable costs are
the material costs (and perhaps energy)
associated with the incremental order - TOC claims that material expenses are the primary
short-term variable costs. - ABC was never intended to measure short-term cost
behaviour.
20TOC, Operating Expense Validity
- 1. How did operating expenses reach their current
level? - 2. All organizations in the same industry and the
same line of business have the same level of
operating expenses?
21TOC, Assessment
- The assumptions of TOC are excellent
approximations of the reality for the problem.
TOC has been designed to solve short term product
mix and scheduling of bottleneck resources. - This is a problem for which ABC provides little
insights since during such a short period, all
organizational expenses, other than materials and
energy, are pre-committed.
22Enterprise Resource Planning Systems
- An ERP can provide a firm with an integrated set
of operating, financial, and management systems. - An ERP has a a common data structure and a
centralized, accessible data warehouse that
permits access from any of numerous systems or
modules. - An ERP allows all systems and modules to be
brought into a single integrated system. - Integrates financial accounting, ABC, operational
feedback, inventory, budgeting, etc.

37SAP, Process Redesign
- SAP almost always forces a firm to redesign its
business processes - Process redesign is changing strategic
value-added business processes and the systems,
policies, and organizational structures that
support them, in order to optimize productivity
and the flow of work. - The goal of process redesign is to eliminate
non-value adding work, not necessarily to
eliminate jobs. - Process redesign with SAP allows the automation
of low-value adding work
38Process Redesign, Themes
- 1. Gets products to customers
- 2. Uses sophisticated IT
39Process Redesign, Foci
- 1. Reduction in process costs and time
- 2. Improvement in quality and customer service
