Week 4 April 23, 2002 Group Dynamics ETM 5221 - Engineering Teaming Spring 2002 2
Agenda • A quick review of difficulties with groups • Helping direct group dynamics • Jelled teams and productive workplaces • The mythical man-month • Key features of the Group System Concept ETM 5221 - Engineering Teaming Spring 2002 3
Meeting purposes: Almost 2/3 involve complex group processes (Monge, P. R. , Mc. Sween, C. , & Wyer, J. 1989) ETM 5221 - Engineering Teaming Spring 2002 4
Look who’s talking • Traditional Teamwork – Boss talked 33% of time – Next person 22% • Technology Supported Teamwork – Boss talked 5 % – Next person 8% (From Romano) ETM 5221 - Engineering Teaming Spring 2002 5
A quick review of difficulties with groups • Some tasks are simply not well suited for group methods or processes • Often develop preferred ways of looking at problems that can inhibit innovation • Synergistic effect can be absent – For example, brainstorming doesn’t exceed performance of individually produced and combined results ETM 5221 - Engineering Teaming Spring 2002 6
Difficulties (continued) • Politics, power, and position can dominate methods or results – Or can suppress contributions of others • A group fulfills social needs, but group seldom has ways of regulating amount • Fairly reliable characteristic of groups to get off track and get stuck there ETM 5221 - Engineering Teaming Spring 2002 7
Difficulties (continued) • Groups tend to have relatively low aspiration levels with respect to quality of solutions accepted – Once some level of acceptance is inferred, little further search happens • Often lack concern and method for dealing with way to best utilize and communicate members’ knowledge ETM 5221 - Engineering Teaming Spring 2002 8
Difficulties (continued) • Strongly influenced by cultural norms – In natural groups, members tend to be conservative, circumspect • If the group’s efforts do not appear reinforced, effort is reduced • As group size increases, effort contributed by each individual member tends to decrease ETM 5221 - Engineering Teaming Spring 2002 9
Difficulties (continued) • Reliably exhibit norms against devoting time to planning their methods – Move immediately to attacking problem, relying on implicitly shared methods – Considerable likelihood that method is poorly adapted to task and only modestly effective – Seldom have ability to change the method when things not going well ETM 5221 - Engineering Teaming Spring 2002 10
Effective use of roles and process help direct dynamics • Group process management roles • Group process member roles – Task – Maintenance – Non-productive • Group process communication patterns • Team member roles ETM 5221 - Engineering Teaming Spring 2002 11

Major problems not so much technological as social • Most managers agree, but then don’t manage this way – Background and training – High tech illusion » Mostly in human communications business – Easier to do ETM 5221 - Engineering Teaming Spring 2002 66
Development inherently different from production • Encouraging some errors (experimentation) vs. squeezing out errors • Working smarter vs. pressure to work harder • Unique, skilled knowledge work vs. routine production or service work ETM 5221 - Engineering Teaming Spring 2002 67
Development inherently different (cont’d) • Dynamic effort vs. steady state • Effectiveness (doing right things) vs. efficiency (doing things right) ETM 5221 - Engineering Teaming Spring 2002 68
People under time pressure don’t work better, just faster • More per hour of pay or more per hour of work? • The push of delivery dates and tight schedules • The pull of other places, other things • Overtime less Undertime equals zero • Risk of increased turnover • Productivity as benefit divided by cost ETM 5221 - Engineering Teaming Spring 2002 69
Quality leads to higher productivity • Market derived quality standard make sense only if effects on builders ignored – To builders, tied to self-esteem, pride of work – Builders chided for tinkering, then blamed for poor quality ETM 5221 - Engineering Teaming Spring 2002 70
The new converging conference room walls 71 helped make meeings short and to the point. ETM 5221 - Engineering Teaming Spring 2002
High quality, low cost: like having cake and eating it too • Improved quality often requires significant investment • The power of veto over delivery ETM 5221 - Engineering Teaming Spring 2002 72
Organizational busy work tends to expand to fill day • Parkinson’s Law – work expands so as to fill the time available for its completion – Doesn’t apply to most people – Research suggests programmers more productive when setting own schedule » And even more productive when set by systems analyst » And still more productive when no estimate prepared – When to apply schedule pressure? ETM 5221 - Engineering Teaming Spring 2002 73

Quantity of hours easier to measure than quality • Gilb’s Law – Anything you need to quantify can be measured in some way that is superior to not measuring at all • Effective use requires that management cut itself out of the loop – Individuals inclined to use data for improvement ETM 5221 - Engineering Teaming Spring 2002 79
Typical objections to rearranging physical space • People don’t care about glitz – Doesn’t mean they don’t care about any workplace attributes • Cheaper ways to deal with noise – The effects of lost creativity are cumulative ETM 5221 - Engineering Teaming Spring 2002 80
