Operations Strategy
There’s nothing here to take by storm; to strategy we
must conform.
Johann Wolfgang von Goethe (Faust,1808)

Principle 1 (Value Maximization) The goal of strategy
is to maximize the long run NPV of the organization.
It is not a pure NPV defined for shareholders, it also
takes into account stake holders (social
responsibilities), as well as environmental impact
(sustainability).
Competitive strategy (Business Unit Strategy).
Relates a company to its environment. Strengths and
weakness of the company (the system) to be related
to opportunities and threats in the environment
Chooses an attractive competitive position  by
offering a high customer value proposition.

Organizational Resources


Organization is a bundle of real recourses.
Real Resources



Tangible real resources: human resources (people) and
capital resources (property, plant and equipment).
Intangible resources: relationships with suppliers or
customers, reputation and brands, technology and know
how.
To pay for the real resources, sell pieces of paper;
financial resources; securities.

Operations Strategy: Resource View
1. How many resources should we invest in? The capacity, in
aggregate and per main resources.
2. When should we increase/reduce resources over time? The
availability of capacity and the timing of capacity
3. What kinds of resources? HR or CR? The trade-off between capital
and human (unsupervised operations). What degree of flexibility?
from single-task (hard- targeted towards producing a specific
product) to multi-task (flexible- to produce a continuum of
products)?
4. Where should the plants be located and what is their roles in the
supply chain – each location is responsible for what parts or
products. What is the topology connecting these nodes of supply
chain? - FedEx: hub-and-spoke, Car companies: tiered or tree.
What are the modes of transportation in the network? T? R? A? W?
Are the processes standardized or localized; e.g., should Mercedes
Benz processes in be similar to the German processes?

Operations Strategy: Process View



The process view  how resources perform activities and
add value. 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
value-added 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). It represents interfunctional relationships as well as the external interfaces
with customers and suppliers.

Operations Strategy: Process View
1. Sourcing decisions: make or outsource?, supply
network (how many suppliers and how to manage
them?), vertical integration.
2. Which technologies ? Four types of technology:



Product technology: Is the product designed in modules
or as an integral system? Does the design take into
account manufacturability and reusability?
Process technology: The transformation process and
methods. The physical layout (job shop vs. flow shop)
and material (unit load) flow pattern.
Coordination and IT: Centralized vs. distributed planning
and control? planning systems (e.g., ERP),
communication technology (e.g., Internet, RF).

Operations Strategy: Process View

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.
3. How do we match demand and supply? Demand
planning and forecasting, tactical capacity allocation
and revenue management; airlines and hotels.
4. How and when do we improve and innovate in
products and processes? R&D, continuous
improvement, learning and knowledge management.

Values




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

Operations Strategy: Competency View
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.
1.Cost, including input costs and resource costs. Is important in low
margin markets.
2. Flow time. Responsiveness (short flow time) is important due to
changes in customer preferences and technologies. Both Flow
time and reliability in flow time (standard deviation).
3. Quality. Quality refers to the degree of excellence of the product
and process. It has product dimensions such as performance and
features and process dimensions such as durability and
reliability (retaining high quality over time). Is a key
differentiator in luxury and high precision businesses.
4. Flexibility. Ability to change type and volume of the operations.

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.

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.
Alcoa started with low price of electricity, then developed
Aluminum smelter processes and exported the processes.
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.

A Framework For Operations Strategy
1. Organization  Customer value proposition for each
market segment?
2. Operations  Prioritize competencies for each market
segment?
3. Which resources and processes best provide that
competency prioritization? For each targeted
customer segment, how the resources (sizing, timing,
type, and location) and processes (supply,
technology, demand, and innovation management)
are configured?

congruent set of objectives in terms of demand
(product, market) and supply (input, technologies,

operational excellence, 40% gross margin, 70% of
patients pay almost nothing, and the hospital does
not depend on donations.
A focus process is not limited to a few products.

PWP: The business strategy is diverse. But the
entire business is divided into several mini-plants
each with focused processes. One PWP may focus on
low cost, the other on quick response.
To sustain competitive advantage, a firm must
ensure that its competitors are not able to imitate
its chosen position. An sculpture not a block.
Supporting the strategic position with multiple
mutually reinforcing activities creates a sustainable
competitive advantage. It is harder for competitors
to imitate an array of interlocked activities.

This "top-down and outside-in" ensures that
operations reflect the intended market position.
Market driven strategy creates a customer-driven
organization.
In “a bottom-up and inside-out”, the building blocks
of strategy are not products and markets, but
processes and resources. The value proposition
offered to customers seeds in the operational
capabilities. The technology driven strategy creates a
resource-driven organization.

Organizations must maintain alignment by adopting
both perspectives. In order to satisfy a new customer
need, the firm may need to build new competencies,
processes, and resources. Those operational
capabilities may later be used to invent new products
and services that may create new markets.
Honda's abilities and knowledge in high-performance
engine technology has been the driving force in
deciding which markets to enter and which products
to offer.

facilities (also outsources locally), two major DCs, and
90% of 724 retail stores.
The design capacity of 11K new styles/yr by over 200
professionals is in line with the timely fashion (design
to rack of 3 weeks).
Owns two central warehouses in Spain. The recent
123,000 m2 DC has a capacity of 80K garments/hr.

utilization is 50%, many facilities are single shift.
The supply network centered in Spain (25% from the
rest of Europe and 25% from the rest of the world).
The proximity of suppliers  inputs are received
quickly  fast speed-to-market. Local facilities are
used to produce the products with most demand
uncertainty and time-sensitivity, off-shoring for basic
products with more predictable demands. Industries
exercising (fast response times + high demand
volatility) experience low capacity utilization

Short lead time for product with high variability in
their demand. Local manufacturing processes have
short setup times and run in small batches, while offshore manufacturing of more predictable demand can
have longer lead times.
Distribution is highly centralized to reduce the
number of stocking points and the associated
handling time and so that one store's upside demand
fluctuations can offset another's downside.

Intentionally short style campaigns that are likely to
run out of stock create a scarcity image. Customers
visit stores frequently and are likely to buy what is
available at that moment because that particular
product may no longer be available next time. The

Fast new product design is a key enabler of Zara's
strategy. Ideas inspired by urban hot spots, fashion
shows, and store customers are transmitted to the
creative teams. Design style platforms are created
ahead of the season and are modified just before
production based on feedback from retailers regarding
the most recent fashion. This postponement of design
styling requires fast and efficient information transfer.

Should Every Retailer Adopt the Zara Model?


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.

Should every retailer adopt the Zara model?

The Zara model is not used in other industries such as
toy, cell phone, or auto manufacturing. Zara model
requires:
1. High customer willingness to pay for speed-to-market.
2. Short product life cycles with high demand uncertainty.
3. Low cost of excess capacity with low importance of scale
economies.
4. Low cost of stockouts and distribution relative to inventory
holding.

Great operations strategies are tailored to each
company's competitive strategy. While companies
may share some elements, a complete tailored
operations system is unique
