Joint Activity

New synthesis of key aspects of team coordination. Joint activity depends on mutual predictability of the participants’ attitudes and actions which is based on common ground—pertinent knowledge, beliefs and assumptions that are shared among the involved parties. Joint activity assumes a basic compact, which is an agreement (often tacit) to facilitate coordination and prevent its breakdown. One aspect of the Basic Compact is the commitment to some degree of aligning multiple goals. A second aspect is that all parties are expected to bear their portion of the responsibility to establish and sustain common ground and to repair it as needed. Joint Activity pdf

Handoffs and shift change

As hospitals across the United States develop policies to prevent worker fatigue and ensure patient safety, a study at Ohio State University has identified key strategies that might make the job easier. Culled from high-risk environments as diverse as a railroad dispatch center and the NASA Johnson Space Center, the strategies address the most critical time during any workday -- the shift change -- when incoming and outgoing workers have to exchange information and hand-off important duties. handoffs in health care pdf

Supporting Intelligence Analysis

W. Elm, S. Potter of ManTech/Aegis CSEC with D. Woods of OSU have developed a framework of what is support for intelligence analysis.

The basic insight is that success in analysis work is a process of convergence, while the risk is premature narrowing. The diference is that convergence alternates narrowing processes in cognitive work with broadening processes. The framework has 3 generic processes -- down collect that identifies potential relevant source material, conflict and corroboration that develops a set of findings to be explained, and hypothesis exploration that develops a coherent explanatory story that accounts for the findings. In between the support functions for these processes are phases of broadening checks (see entry on Study of Analysts under Data Overload for one set of supporting evidence). Successive cycles of narrowing and broadening produce convergence and avoid premature narrowing.

The framework of support functions is illustrated in these animations produced by A. Roesler (28 Megs and 11 Megs respectively):

Discovering How Cognitive Systems Work

Chapter from "Handbook of Cognitive Task Design," E. Hollnagel (ed.), Erlbaum, 2003. CTD Handbook Chapter pdf
Given the starting point that field settings also function as natural laboratories, the chapter shows how different classes of methods represent different ways to shape the conditions of observation. The chapter discusses the relationship of in situ obervation (or natural history techniques), staged or scaled world simulations, and experimenter created artificial tasks. The chapter provides guidance, especially on how to carry out process tracing methods.

Envisioned World Problem

The envisioned world problem--
~ How does one envision or predict the relation of technology, cognition and
collaboration in a domain that is in a process of becoming?
~ How will envisioned technological change shape cognition and collaboration?
~ How will practitioners adapt artifacts, given new capabilities and new
complexities to meet their own goals?
~ How can we predict the changing nature of expertise and new forms of failure
as the workplace changes?

For description of the envisioned world problem see pages 3 to 7 of animock pdf
It is also discussed in the following paper: technology change pdf
