Customer Value Proposition


Customer Value Proposition: a set of benefits that the firm
offers to customers.
Customers purchase based on the value they derive from
the product/service. This value is the greatest amount a
customer is willing to pay (the reservation price).
If this value > price, the customer enjoys positive net
value (consumer surplus). Customers will buy the
service/product that offers highest consumer surplus.
Zara's main business is the design, manufacture,
distribution and retailing of clothing. Differentiates itself
from rivals  timely fashion for the masses. The customer
value proposition  timely yet limited variety at modest
cost and quality.

Mercedes-Benz
In 1993, Mercedes-Benz decided to build the first factory
outside Germany, in Tuscaloosa, AL to produce the M-class
(to cut tariff by 25%).
A Consolidation Center opened near the plant to manage the
parts/subassemblies from 65 suppliers.
A distribution network to transport the vehicles to 135 countries.
The firs car was sold in 97. Demand quickly surpassed all
forecasts and the capacity of 65,000.
The initial $300 million plant was expanded in 98-99 to 80,000
at a cost of $80 million; still insufficient. In 1999-2002, the
M-class was also produced by contract developer in Austria.
To produce R-class too in AL, a $600M expansion in 2004
doubled the factory size; 4000 workers, 160K vehicles per
year.

Operations Strategy: Resource View
1. How many resources should we invest in? The capacity,
in aggregate and per main resource type. MB, the
aggregate annual capacity was 65000 at 1993.
2. When should we increase or reduce resources? The
availability of capacity and the timing of capacity
adjustments. MB, 85000 in 99, 160000 in 2004.
3. What kinds of resources are best? HR or CR? To what
extent can a capital resource operate unsupervised? i.e.,
the level trade-off between capital and human. What
degree of flexibility is required? from single-task
(specialized) to multi-task (flexible)? How the 160K
capacity split into M and R-classes? Are the assets
specialized to produce one or flexible to produce both?

4. Where should the plants be located and what is their
roles in the supply chain? How should the M-class plant
location be chosen and what responsibilities should it
have. Location decisions are part of network strategy
which also includes topology (FedEx: hub-and-spoke,
Car companies: tiered or tree) and configuration (
transportation modes). Also whether processes should
be standardized or localized; e.g., should Tuscaloosa
processes be similar to the German processes?

The process view  how resources perform activities and add
value. A process is a network of activities with precedences.
By starting with inputs (customer demands) and ending with
outputs (served customer demands), the process view is
compatible with a customer-centric view of the world.
From this customer-centric view, value stream mapping
defines value from the perspective of the customer: a valueadded activity is an activity that benefits the customer.
The process view: a horizontal view of the organization that
cuts through functional silos ( finance, accounting,
production, marketing sales, etc). Inter-functional
relationships as well as the interfaces with external customers
and suppliers.

Coordination and IT: Centralized or distributed planning,
control? In planning phase  coordinate financial, sales,
marketing, and operations forecasts. In the execution
phase  making events happen at the right times.

Product technology: Is the product designed in modules
or as an integral system? Does the design take into
account manufacturability, testability, or reusability?
Process technology: The transformation process and
methods. The layout of the process in terms of the
physical arrangement and flow pattern of the unit loads,
i.e., job shop or flow shop.
Transportation technology: material handling in the
plant and transportation network throughout the supply
chain. Also includes how insurance policies are moved
between the different processing steps.

The Competency View of Operations




Values are a third factor that affect what an operation
(or an organization) can and cannot do.
Values are the standards by which employees set
priorities at every level. Some priorities are
programmed into a process but many are not. Ex.
whether an order or customer is attractive, whether
a suggestion to improve a product or process is
attractive, whether an investment is worth making.
As organizations become more complex, consistent
values are powerful mechanisms for employees to
make independent but consistent decisions.
Values constitute the organization’s culture

The Competency View of Operations


The competency view characterizes the abilities of the
organization's resources, processes, and values.
Competencies determine the set of outputs that the
operation will be particularly good at providing.



A premier management consulting company is good at
providing high quality customized advice.
An efficient operation such as McDonald's is good at
delivering inexpensive food quickly, but from a standard
and limited menu with a well-defined quality level.
Zara is good at quickly delivering a large selection of
new designs at a reasonable cost.

Operations Strategy: Competency View
1. Cost, including input costs and resource costs. Is important in
low margin markets.
2. Response or lead time. The time needed to transform inputs into
outputs? Responsiveness is important due to changes in
customer preferences and technologies.
3. Quality. Quality refers to the degree of excellence of the process,
product, or service. It has design-related dimensions such as
performance and features, as well as process-related dimensions
such as durability and reliability. Is a key differentiator in luxury
and high precision businesses.
4. Flexibility, to change inputs, activities, volumes, or outputs.
Similar to quality, flexibility has several dimensions such as
scope flexibility (the selection or range of products and services
offered, including the level of customization), volume flexibility,
and robustness.

The Competency View of Operations

Foundations of competencies change over time; they
start in resources, gradually migrate to processes,
and eventually reside in values.




Most of what gets done in start-up companies is attributable
to inputs and resources. Losing a person can be detrimental.
As activities become more recurrent, processes are defined.
As it becomes clear which business needs should be given
highest priority, values emerge.
With hundreds of new recruits and departures per
year, top management consulting companies remain
successful because their processes and values are so
strong that project staffing changes have little impact.

Zara's operational system is not a panacea. Sweden's
Hennes & Mauritz AB competes with Zara. It produces
much fewer new styles per year with a much slower
design-to-rack time of 16 weeks.
Without the stringent speed requirement, H&M has
more leeway in configuring its operations; more
outsourcing and higher capacity utilizations resulting
in much lower fixed capital. The lower safety capacity
and responsiveness is replaced by higher safety stock
to buffer demand uncertainty.

Whereas the strategic operational audit is a highlevel
tool for improving fit, the product-process matrix

and delivered product attributes.
The product-process matrix starts by evaluating the
promised value proposition and the process used to
deliver value. It verifies alignment along one
dimension, often by comparing the degree of variety
in the value proposition with the degree of process
flexibility. This combination is then represented by a
covered area in the matrix where the distance to the

Threestar chefs who serve simple meals (burritos and
tacos) with their highly flexible job shop process incur
high opportunity costs. Substantial savings would
result from changing resources (including chefs) and
streamlining the process into a flow shop.
Asking Chipotle's to change its menu daily would
