Topic

Development and Application of general modular systems theory

Purpose

Develop a general theory of modular systems drawing on system theories from many disciplines

Apply the general theory to derive a model of interfirm product modularity , integrating the existing constructs

associated with product modularity

Contributions & Implications

Developed a casual model tying various constructs together to explain the adoption of increasingly modular

forms(especially product designs) , filling the research gap

Implications for management and public policy

1. Overview

2. Modular systems

Definition

All entities are a system of components and each of those components is a system of finer components, which could

be perceived as hierarchically nested systems

System hierarchy could overlap enabling the components to serve multiple systems

System should be distinguished from context within which it exists

Warm up Q ; Modular vs. Integrated design

Modular design 과 Integrated design 의 장점 / 단점 ?

Modular Integrated

장점

Module 내부에서는 interdependency 를 고려하지만 Module 간 Interdependency 는 줄여 효율성과 생산성을 높일 수 있다

Economies of scale 이 가능하다

구성요소간의 Interdependency 를 만족하는 수준에서 개선된 값을 도출하는 과정에서 innovation 이 발생할 수 있다

구성요소간 Interdependency 의 고려로 최적화된 디자인이 도출되기 때문에 높은 Performance 를 기대할 수 있다 .

단점

Module 화 하기 위한 작업에 시간과 비용이 많이 들어간다

Module 간 interdependency 를 제대로 파악하지 못할 경우 실패로 이어진다 .

Standardization( 표준화 ) 의 과정이 선행되어야 한다

구성요소의 숫자가 늘어날수록 Iteration 에 들어가는 시간과 비용이 급격하게 늘어난다

Exploration 의 속도가 느리고 한번 정해진 디자인의 변화가 쉽지 않다 .

2. Modular systems

Main factors & Assumptions

1. Fitness and Adaptation : The degree to which the system and its context are “Mutually acceptable”

가정 : 복잡한 시스템의 경우 context 나 더 좋은 fitness 의 방향으로 Adaptation / Evolution 할 수 있다 .

Context creates forces that draw a system toward a particular state

System often will not achieve an optimal fit with its context : issue of Inertia / Time

System and its context coevolve ; 저자는 Deterministic perspective (system responds to its environment) 에서 주로 바라봄

2. Coupling and Recombination

가정 : 모든 system 들은 components 간 어느 정도의 coupling 으로 이루어져 있고 완전히 분리 불가능한 system 은 거의 없다 . 즉 모든 system

은 Modular 하다 .

Speparability (influenced primarily by the degree of synergistic specificity characterizing the system) is the strongest factors

conditioning whether a system will respond to pressures to become more modular

Heterogeneity of inputs and demands : system 을 구성하는 Heterogeneous 한 input 이 많을 수록 recombination 을 통해 만들어 질 수 있는

configuration 이 많아진다 . 또한 Heterogeneous 한 demand 가 많을 수록 recombination 의 value 가 높아진다 . 추가적으로 가능한

Configuration 이 많을 수록 heterogeneous 한 demand 을 만족시킬 수 있는 system 이 만들어질 가능성이 높아진다 .

Heterogeneity of inputs + Heterogeneity of demands = Powerful incentives to adopt a modular design

2. Modular systems

Main factors & Assumptions

3. Migration and Equilibria

The balance between the gains achievable through recombination(Modular) and the gains achievable through

synergistic specificity determines the pressure for or against the decomposition of the system

Trajectory of system is bidirectional : as the environmental changes or the separability of the system changes, the

system might migrate up or down a trajectory, toward or away from increasing modularity

4. Overcoming Inertia

Systems do not respond immediately and vigorously to every external influences ; Inertia

즉 , 항상 실제 separability , heterogeneous input/demand 에 비해 더 modular 하거나 덜 modular 하다

To what degree a system responds to changes in its context are influenced by forces in the context that create

urgency

Ex) Time / Competitive intensity can catalyze the balance

Discussion 1

Industry 의 전반적인 측면에서 보았을 때 Modularity 가 심해지면 , 각 components 를 생산하는

Vendor 간의 힘이 평등한 것이 아니라 ( 본 논문에서의 Windows) 어떤 제품의 Core 한 요소를

생산하여 이에 대한 Standard 를 가지고 있는 Vendor 가 가장 Bargaining power 가 강해질 것이라

생각된다 . 이러한 상황은 오히려 Industry 전반에게는 Innovation 을 저해하는 요인이 되지 않을까 ?

본 논문에 의하면 Modularity 가 증가하면 증가할 수록 , 고객은 다양한 Needs 에 맞춰 다양한 선택지들 중에서 원하는 것을 고를 수

있어 Switching cost 를 낮출 수 있는 이점이 있고 vendor 의 입장에서는 Specialization 을 통해 제품을 이루는 모든 Components

를 관리하고 생산하지 않아도 되기 때문에 결국 Fixed cost, variable cost, inventory cost 등의 비용에서 절약을 할 수 있게 되고

이에 따라 Margin 을 얻기 위한 비용이 낮아져 Product cost 자체를 낮출 수 있는 장점이 있다고 한다 .

하지만 , 이를 다른 측면에서 생각해보면 , Modularity 가 이루어질 수 있는 전제 조건이 Standardization 임을 고려했을 때 어떤

제품을 구성하는 Component 중에서도 Core component 를 생산하는 vendor 의 힘이 강해지고 이로 인해 결국 industry 전체의

innovation 가능성을 저해됨과 동시에 Standard 가 요구하는 조건을 맞추기 위해 다른 vendor 들은 오히려 높은 비용이 드는

경우도 있을 것 같다 .

3. Interfirm Product Modularity

Product systems are modular

Interfirm modularity enables customers to assemble their own multivendor configuration

Modularity within the firm enables economies in design and simplify coordination

Modular technologies give users greater discretion over the function and scale of the end product, enabling

users to create products that perform functions more suited to their needs

Enables customers to use components from a variety of different vendors rather than being locked into a single

vendor

Application of general theory to Interfirm product modularity

앞에서 도출한 General modular systems framework 를 product level 에 적용시킴으로써 어떻게 Dominant design of

a product system 이 modularity 를 증가 혹은 감소시키는지에 대한 이해를 할 수 있다 .

Heterogeneity of input/demand and Urgency : External factors

3. Interfirm Product Modularity

Others (not related to propositions)

1. Network Externality

Firms can reap advantages of compatibility with a wide range of complementary goods by encapsulating

proprietary technology within a components that conforms to an open standard based architecture while

still retaining the rent generating potential of their proprietary component

2. Market power and architecture control

If a firm possess a unique asset or position in the market, it can respond to the pressure of heterogeneous

inputs and demands

4. Impications

Management

Understanding product system’s migration toward increasing or decreasing modularity is valuable both to incumbents

and new entrants

Policy makers

Some industries will benefit from increasing integration whereas some will not

Model helps to clarify when integration is desirable from the customer’s point of view and when it actually constitutes

an injurious tie-in

Expectations of certain industry

For what degree of concentration we should expect to see in an industry

Strong customer, technological and firm pressure to deliver an integrated product ; Greater industry concentration and

larger firms in the industry

Strong pressure of modularity ; Fragmented industry

Discussion 2

Product 외에 Modularity 가 적용될 수 있는 것은 어떤 것이 있고 , 적용될 수 있다면

구체적으로 어떤 방식으로 적용될 수 있을까 ? 서비스의 경우 Platform 화와 차이가 있는가 ?

본 논문에 의하면 모든 System 들은 기본적으로 Modular 한 성격을 가지고 있다고 한다 . 하지만 논문에서 구체적으로 다루고 있는

것은 Interfrim product modularity 이다 . Product 의 경우 Design 의 과정에서 Modular 혹은 Integrated 의 방향으로 명확하게

구분 지어 개발될 수 있다고 생각한다 . 예를 들어 Integrated 의 경우는 과거 일본의 Compact 한 전자제품들이라던가 아니면

Apple 제품의 디자인이 있고 Modular 한 경우 Google 의 경우나 Samsung 제품의 경우를 들 수 있을 것 같다 . 하지만 서비스의

경우나 다른 어떤 형태의 경우는 선뜻 떠오르지 않는데 어떤 것이 있을까 ?

또한 , 서비스의 경우 Modular 하게 개발할 경우 Platform 의 형태와 비슷할 것으로 예상되는데 이에 대해서는 어떻게 생각하는가 ?
