Enterprise Systems and Transformation

Learning outcomes

After completing this chapter, the reader should be able to:

  1. Explain enterprises as open dynamic systems: purposeful wholes maintaining themselves through continuous exchange with an environment, and formalize this claim in the system septuple of Definition (see book).
  2. Distinguish systems, subsystems, and environments, and apply the distinction consistently to concrete enterprises at several levels of resolution.
  3. Describe enterprise boundaries and interfaces, explain why boundary placement is a modeling decision, and state precisely what is and is not invariant to that decision (Theorem (see book)).
  4. Explain feedback and adaptation, distinguish them formally (feedback acts on inputs; adaptation acts on the rule), and reduce adaptive systems to ordinary systems on an augmented state space (Proposition (see book)).
  5. Interpret transformation as system evolution: a designed change of state, structure, or rule, formalized as the enterprise transformation process of Definition (see book).
  6. Relate systems concepts to enterprise modeling, identifying for a given analytical question the appropriate boundary, resolution level, and feedback structure.

Exercises

16 exercises, grouped A concept checks · B mathematical · C computational · D enterprise applications. Starred (★) exercises are on the advanced track. Full solutions appear in the Instructor's Manual, Chapter 2.

A. Concept checks

  1. 2.1
    For an enterprise you know well, instantiate every slot of the septuple (see book) in one line each, at enterprise-level resolution.
  2. 2.2
    Using Table (see book), explain why a run-off insurance portfolio approximates a closed system and why the approximation degrades over time.
  3. 2.3
    Classify each of the following recurring boundary debates as a choice of BB in Definition (see book), stating for each what moves between interface and interior: (a) franchisees; (b) a 40 (d) a sole-source supplier under a ten-year contract; (e) a captive finance subsidiary.
  4. 2.4
    Give Meridian's three-level hierarchy explicitly and, for the Advanced Materials division, list its environment per Definition (see book).
  5. 2.5
    Classify each of the following as negative or positive, and as first- or second-order, feedback (Table (see book)): (a) a thermostat-style working-capital policy; (b) a bonus formula revised after a risk failure; (c) viral referral incentives; (d) an annual strategy review that changes capital-allocation rules; (e) credit-rating downgrades raising funding costs.
  6. 2.6
    State, in two sentences without symbols and then in one line with symbols, the difference between feedback and adaptation.

B. Mathematical exercises

  1. 2.7
    In Proposition (see book), the absence of algebraic loops relied on the output map having no direct input channel.
  2. 2.8
    Write out the augmented system of Proposition (see book) fully for the scalar case xk+1=θkxk+uk+wkx_{k+1} = \theta_k x_k + u_k + w_k, uk=−θkxku_k = -\theta_k x_k, θk+1=θk+η (xk2−c)\theta_{k+1} = \theta_k + \eta\,(x_k^2 - c), identifying FF explicitly.
  3. 2.9
    Prove the following supplement to Theorem (see book)(iii): if B⊆B′B \subseteq B' and both induce the same classification of FF, then every entity of B′∖BB' \setminus B is flow-disengaged (∉EF\notin E_F).
  4. 2.10 ★
    Let E={1,2,3}E = \{1, 2, 3\} with flows F={(1,2,κ1),(2,3,κ2),(3,1,κ3)}F = \{(1,2,\kappa_1), (2,3,\kappa_2), (3,1,\kappa_3)\}.

C. Computational exercises

  1. 2.11
    Write a one-page memorandum to Meridian's board resolving the dealer-network boundary question.
  2. 2.12
    For the hospital of Example (see book), draw the loop diagram containing: occupancy, staffing, fatigue, attrition, quality, and referral volume.
  3. 2.13
    For the bank of Example (see book), express the state-dependence of the decision set as an explicit constraint uk∈U(xk)\uc_k \in \Uc(\x_k) induced by a capital-adequacy rule of the form (risk-weighted assets)/(capital) ≤κ\le \kappa.
  4. 2.14 ★
    Ashby's law of requisite variety [3] asserts, informally, that a regulator must command at least as much variety as the disturbances it regulates against.

D. Enterprise applications

  1. 2.15
    (With AXIOM-02 or the Chapter 2 notebook.
  2. 2.16
    (With AXIOM-02 or the Chapter 2 notebook.
