OUTLINE Background Why simulate organizations? Why start with project organizations? Why use “information processing” as the central modeling framework? VDT Model Concepts and Evolution VDT Applications to Date Using VDT models as “virtual prototypes” Using VDT models as “virtual experiments”
4
The Big Ideas 1.Validated analysis tools are central to design; they distinguish real design from trial-and-error experimentation! 2.In the same way that physical-science-based analysis tools help engineers design bridges, airplanes, semiconductors, pharmaceuticals, etc., social-science- based analysis tools can help managers design their organizations systematically 3.A small number of validated organizational analysis tools are already being used by managers to design organizations for projects, programs, and enterprises (SimVision, OrgCon… ) 4.Validated organizational analysis tools also allow researchers to conduct new kinds of virtual computational experiments
5
Steps in a Formal Design Process START… Set Design Goals Design Synthesize: Develop a candidate design solution Analyze: Predict candidate solution’s performance Evaluate: Compare predicted performance vs. goals Iterate Designs u Relax Design Goals …TERMINATE—Success or Failure?

SCOPE: Product Development Organizations? I. Practical Motivation—High Economic Importance Product lifecycles and market windows are shrinking for many consumer and industrial products, To accelerate time-to-market, complex, highly interdependent work processes must be executed concurrently This causes an exponential increase in the amount of needed coordination work and rework Insufficient “information processing capacity” emerges as a leading cause of “failure” in product development organizations Extant theory and tools cannot help managers to predict whether, when and where their organizations will fail due to information processing overload
10
Why Study Product Development Organizations? II. Theoretical Motivation—Perfect fit for IP framework Task Interdependence Goal Incongruency/Ambiguity Task Routineness
11
Fast Track Projects are Information-Intensive High performance, complex product has high level of inter- dependency between its subsystems Fast-track schedule triggers unplanned coordination and rework for project organization ProcessOrganizationProduct Project team must process large amount of information under extremely tight time constraints
12
Using an “Information-Processing” Simulation Framework to Design Project Organizations 1.Model work process to determine “IP load” on organization arising from direct work, coordination and rework 2.Use simulation model as “virtual prototype” of real organization executing work process 3.Highlight predicted bottlenecks in IP capacity as likely loci of schedule and quality failures 4.Evaluate alternative “virtual prototypes” of work process and organization to test and select potential managerial interventions
13
What Affects Frequency of Exceptions for Workers and Managers in Projects? For Workers: Task complexity relative to workers’ skills Task interdependency Task concurrency For Managers Above factors, plus: Organizational span of control Level of decentralization
14
OVERVIEW OF VDT REPRESENTATION & REASONING
15
VDT Info-Processing Abstraction Workers Process Information = “Direct Work” TASK/ACTIVITY: (Volume of Information) “ACTOR”: (Information Processor) Coordination & Rework
16
Exceptions must be Processed by the Organization = “Hidden Work” (Jay Galbraith, 1973) “Exception”
17
Direct Work is not Total Work! Total Work = Direct Work + Hidden Work (Jay Galbraith, 1973) Project Organization must also Coordinate and Supervise + “Exception” Project Participants Perform Assigned Tasks Direct Work “Hidden Work”
18
Fast-Tracking Amplifies Hidden Work
19
REPRESENTATION CPM to model processing of direct work Add two additional kinds of task interdependence Add actor skill levels, application experience Add organization structure, culture, meetings …
20
Information Volume from Project Tasks & Dependencies: Direct Work, Communication Work and Rework
21
Project Team Information Processing Capacity: # Actors, Skill Set, Experience, Structure, Policies
22
VDT Information Processing Model: Matching IP Capacity to IP Demand
23
REASONING Monte-Carlo discrete event simulation of information processing and communication Used previously to model flow of physical work and materials through a supply chain In VDT, direct work and hidden work are both simply quanta of information to be processed by humans and information processing/communication tools
24
Communications to other actors “Out tray” Actor “In tray” Communications from other actors Direct Work VDT Simulates Actors Working and Communicating Simulates: - every actor (team) & activity - work, errors, coordination, waiting, decisions, rework Produces: - “database” of actor and project behaviors/outcomes Simulates: - every actor (team) & activity - work, errors, coordination, waiting, decisions, rework Produces: - “database” of actor and project behaviors/outcomes

Research Modalities in Engineering Science — (Pre-1960s) Empirical Data Inputs Outputs Physical Scale Models Inputs Outputs Empirical scaling rules Theory Physics Chemistry Biology (generally expressed as sets of linear or differential eq’s.)
45
Limitations of Physical Scale Models Costly and time-consuming to build Required skilled physical model builders (often built by model shop technicians—not scientists) Slow and costly to modify Scientists could not adapt models rapidly to react to surprising data or to test new insights Calibration against real world data took decades Results needed to be interpreted with care Many important effects do not scale linearly
46
Physical Scale Models Inputs Outputs Empirical scaling rules Research Modalities in Engineering Science — (Post-1960s) Empirical Data Inputs Outputs Computational Modeling & Simulation Inputs Outputs Limiting modeling assumptions Theory Physics Chemistry Biology
47
How CM&S Affected Engineering Science and Practice Rapidly declining time & cost to build and change models Two orders of magnitude improvement “disruptive” changes Progress of Engineering Science Dramatically Accelerated Could rapidly modify models to test & refine theory iteratively “Regress” micro-modeling assumptions against meso/macro data Engineering practice made huge leaps forward “Real-time” prediction now feasible for even complex problems Wider range of mathematically indeterminate problems can be solved Computational modeling now part of standard BS/MS curricula Model results still need to be interpreted with great care! Violations of assumptions can be catastrophic —e.g. Sleipner platform)
48
Research Modalities in Organizational Science—Pre-1970s Empirical Data from Natural Experiments Micro/Meso/Macro Inputs Micro/Meso/Macro Outputs Span 1 or, at most 2, levels Empirical Data from Synthetic Experiments Micro/Meso Inputs Micro/Meso Outputs Theory Sociology Psychology Economics (usually expressed in words & diagrams; sometimes in mathematical or computational models)
49
Limitations of Synthetic Experiments Modest time and cost to design and perform experiments Validation, calibration against real world data is difficult Individual motivation and context are very difficult to replicate Many effects do not scale linearly Ethical concerns nowadays preclude many kinds of experiments previously conducted on human subjects No links between micro-behaviors and macro outcomes Micro inputs and outputs cannot generally be related to, or reconciled with, macro data or even macro-theory Result: Discipline-Based “Islands of Theorizing”

Empirical Data from Synthetic Experiments Micro/Meso Inputs Micro/Meso Outputs Research Modalities in Organizational Science — Post ~1970 Empirical Data from Natural Experiments Micro/Meso/Macro Inputs Micro/Meso/Macro Outputs Computational Modeling & Simulation Micro/Meso/Macro Inputs Micro/Meso/Macro Outputs Nested models link micro- macro data and theories Theory Psychology Sociology Economics
51
Computational Virtual Experiments CM&S of organizations now beginning to be used to replace some kinds of natural or synthetic social experiments A validated “emulation” model can be viewed as an “organizational test bench” for theorem - proving experiments CMOT Journal has already published several papers of this type (Wong & Burton, Carroll & Burton, …)

How Computational Modeling is Affecting Organizational Science and Mgt. Practice Rapidly declining time and cost to start generating validated predictions for a modeled system u Organization Science poised to make huge leaps forward ÙCan now rapidly modify models to test & refine theory iteratively ÙCan “regress” micro-modeling assumptions against meso/macro data ÙValidated models beginning to serve as “virtual synthetic experiments” u Org. Design practice starting to incorporate CM&S ÙRapid feedback develops “management judgment” by induction Enabling “flight simulation of alternatives” and “extreme collaboration” u CM&S Entering Mainstream Education and Research ÙComputational modeling & simulation now taught as part of PhD/MS/(BS) ÙMIT launching a Center for Computational Politics u Model results still need to be interpreted with care ÙContingency theory says context matters greatly! ÙDifferences in task, technology, … must be taken into account
