Organizational Adaptation and Agility
•
•
•
•
Redundancy in access to personnel, resources, and
expertise
Congruence so that work is performed effectively
Cognitive Demand - Personnel fill multiple roles, and in
particular there are change agents with high cognitive
demand who coordinate others
Transactive memory
•
•
Detailed and “lossy” shared
•
so have high level of shared situation awareness
Organized as small world
DNA tools to measure and assess all of these

The Science of Dynamic Network Analysis
•
•
•
The theory and design of dynamic networks among
diverse entities and the study of all phenomena
emerging from, enabled by, or constrained by such
networks.
Entities include both intelligent agents such as humans
or robots and artifacts such as events, resources and
locations.
Theory, models, metrics, evaluation

Yours, Mine and Ours
Joe: I think Sandy knows
design and is working on
the candy Y add. I wonder
if Bill could work on Soda
Y. They could do it
together.
Sandy: I know design but Joe
knows marketing. I need to
know what products are
bought with soda X so I can
finish the add. Joe should
know who knows this. I’m not
asking Bill – he’s a moron.
Perceptions of the network differ
… sometimes due to “mission”

Network Based Approaches to
Organizational Modeling
Organizations can be represented as a meta-network linking actors,
knowledge, resources, tasks

Challenge: Global Versus Local Constraints
Global – the whole network matters
Local – I know at most 3 degrees out
1) measures computationally less complex
2) derived groups more meaningful
3) needle in the haystack

Is Your Organization a Set of Silos?
Information flow in an extended
leadership team.
Each program area is a different
color.
Large nodes represent program
managers and smaller ones their
direct reports.
July 18, 2015
Same network without program
managers. Despite good intentions
and engaged leadership, the
equivalent of functional silos had
emerged underneath each of the
managers.
This was a problem because people
lower in the hierarchy needed to
connect across programs to provide
services for customers.
