What Is Manufacturing Strategy?
35E00100 Service Operations and Strategy #1 Aalto/BIZ Logistics11
Author Manufacturing strategy connotation Skinner (1969) Refers to exploiting certain properties of the mfg function as a competitive weapon.
Hayes and Wheelwright (1985)
A sequence of decisions that over time, enables a BU to achieve a desired mfg structure, infrastructure and set of specific capabilities.
Fine and Hax (1985)It is a critical part of the firms's corporate and business strategies, comprising a set of well coordinated objectives and action programs aimed at securing a long-term sustainable advantage over competitors.
Hill (1987)It represents a coordinated approach which drives to achieve consistency between functional capabilities and policies and the agreed current and future competitive advantage necessary for success in the marketplace.
Swamidass and Nevell (1987)
The effective use of manufacturing strengths as a competitive weapon for the achievement of business and corporate goals.
McGrath and Bequillard (1989)
Overall plan for, how the company should manufacture products on a world wide basis to satisfy customer demand.
Hayes and Pisano (1994)
In today's turbulent environment a company more than ever needs a strategy that specifies the kind of competitive advantage it is seeking in the markeplace and articulates how that advantage is to be achieved
Berry et al. (1995)The choice of a firm's investment in processes and infrastructure that enables it to make and supply its products to chosen markets
Cox and Blackstone (1998)
A collective pattern of decisions that acts upon the formulation and deployment of mfg resources. To be most effective, mfg strategy should act in support of the overall strategic directions of business and provide for competitive advantage.
Brown (1999)Driving force for continual improvements in competitive requirements / priorities and enable the firm to satisfy a wide variety of requirements.

Competing on capabilities (Stalk, Evans & Shulman 1992)
Noteworthy steps Manufacturing as a competitive weapon (Skinner 1969)

A
35E00100 Service Operations and Strategy #1 Aalto/BIZ Logistics16
• Manufacturing should actively seek to influence corporate strategy and to develop and exploit manufacturing capability proactively.
• Manufacturing (and operations) have been a limited contributor to competitive advantage since most companies are stuck at stage 2.
Stage 1
InternallyNeutral
“Minimizemanufacturing’s negative impact”
Stage 2
ExternallyNeutral
“Achieve parity with
competitors”
Stage 3
InternallySupportive
“Providecredible support to the business
strategy”
Stage 4
ExternallySupportive
“Manufacturing as a
significantcontributor
to competitive advantage”

World Class Manufacturing (WCM) Background
Initiated by the increasing competitiveness of Japanese in the early 80s Behavior among U.S. Manufacturers
Wide implementation of improvement programs such TQM and JIT Use of programs as solutions rather than as stepping-stones
Development of the WCM concept Hayes and Pisano (1986) coined the term
Criticized that lean manufacturing, continuous improvement or WCM are not strategies to gain competitive advantage
Schonberger (1986) “Blended management marshals resources for continued, rapid improvement” Introduced a 17-point action agenda to guide toward mfg excellence
Hanson et al. (1994) and Collins et al. (1996) “WCM is the achievement of standard in both practice and performance that allows to equal or surpass the very
best international plants.” Made empirical analyses in Europe and developed a simple framework.

Key Points
Manufacturing also matters! MPC systems
A basic structure exists Change along with technology, products, market requirements, etc.
Manufacturing strategy Its definition is somewhat ambiguous. Typically at least one of the following is included:
Competitive priorities (cost, quality, delivery time etc.)
Manufacturing approach (MTS, MTO, ATO etc.)
Outsourcing (Make-or-buy)
Alternative paradigms support each other.
Industries and countries differ…
