1 "Content analysis of key words in 30 definitions led the authors to
identify 3 general categories of definitions based on their principal
1.1 These 3 categories "represent a hierarchy in that the
perspective becomes more comprehensive as one
progressively moves from the economic to the
operational to the strategic levels." p727
1.2 1) Economic: the "most rudimentary level" & "the
concern is with the logic of profit generation."
1.2.1 "Stewart and Zhao (2000) approach the model as 'a
statement of how a firm will make money & sustain profit
stream over time'." p727
1.3 2) Operational: "the model represents and architectural configuration. The
focus is on internal processes and design of infrastructure that enables the
firm to create value." p727
1.3.1 "Mayo & Brown (1999) refer to the 'design of key interdependent
systems that create and sustain a competitive business."p727
1.4 3) Strategic: "definitions at the strategic level emphasize overall direction in the firm's
market positioning, intention across organizational boundaries, & growth opportunities.
1.4.1 "Of concern is competitive advantage & sustainability."
1.4.2 "Slywotsky (1996) refers to 'the totality of how a company selects its customers, defines &
differentiates its offerings, defines the tasks it will perform itself & those it will outsource,
configures its resources, goes to market, creates utility for custoemrs & captures profit'."
1.4.3 "Among the available definitions, strategic elements are most prominent." p727
188.8.131.52 "An analysis of models frequently cited as being well
conceptualized (e.g. Dell, Nucor, WalMart, IKEA, Walgreen)
suggests that the elements making these models unique
transcend the architecture of the firm or how it makes money," &
"the model captures the essence of how the business system will
be focused." p727
2 "No generally accepted definition of the term 'business model' has emerged."
3 "Diversity in the available definitions poses substantive challenges for delimiting the
nature and components of a model and determining what constitutes a good model."
4 "The Dell business model integrates strategic considerations, operational
processes, and decisions related to economics. It is designed around elimination
of intermediaries, systems built to order, highly responsive customer service,
moderate margins, rapid inventory turn-over, speedy integration of new
technologies, and a highly efficient procurement, manufacturing, and distribution
4.1 "Adherence to these elements guides
operational decision making and the
firm's ongoing strategic direction."
5 "The business model is related to a number of other managerial concepts. It captures key components of a business plan,
but the plan deals with a number of start-up and operational issues that transcend the model. It is not a strategy but
includes a number of strategy elements. Similarly, it is not an activity set, although activity sets support each element of a

7 "Early work focused on capturing web-based firms.
Subsequent efforts identified model types based on
product offerings, value-creating processes a, and firm
architecture, among other variables." p727
8 "It became evident that the number of potential models was limitless, researchers
began focusing on model taxonomies." p727

model appropriate, ways in which models interact with organizational
variables, existence of generic model types, and dynamics of model evolution,
among other questions." p727
11 "Attempts at model decomposition acknowledge the existence of
interdependencies among other components but shed little light on the nature of
the relationships." p727
