AFM280 Lecture Notes - Lecture 11: Nominal Group Technique, Production Blocking, Process Gain
Chapter 11
WHY ARE SOME TEAMS MORE THAN THE SUM OF THEIR PARTS?
• Some teams might have less talented individuals but as they work together, they become more than
the sum of their parts
• Process gain: when team outcomes are greater than expected based on the capabilities of the
individual members
• Aka. Synergy
• Required in high complex work environment

• Process loss: the opposite of process gain
• What factors conspire to create process loss?
• coordination loss - When members have to not only work on their own parts but coordinate
their activities with other members
• Coordination loss is often driven by production blocking, which occurs when
members have to wait on one another before they can do their part of the team
task
• Motivational loss- loss i tea podutiit ous he tea ees do’t ok as had
as they could
• Motivational loss is driven by the fact that its often quite difficult to gauge exactly
how much each member contributes to the team. Sometimes its less obvious when
a ee otiutes so othes do’t see it. Also, ees of a tea do’t alas
work together at the same time as a unit

TASKWORK PROCESSES
• Taskwork processes are the activities of team members that relate directly to the accomplishment
of team tasks
• E.g. interacting with tools that are used to complete work
• Three types of taskwork process are crucially important: creative behaviour, decision making, and
boundary spanning

CREATIVE BEHAVIOUR
• Focused on generating novel and useful ideas and solutions
• Creative behaviour in teams can be fostered when members participate in a specific set of activities
• The best one if brainstorming
• Most brainstorming centre around the following rules:
• Express all ideas that come to mind (no matter how strange)
• Go for quantity of ideas rather than quality
• Do’t itiize o ealuate the ideas of othes
• Build on the ideas of others
• Such brainstorming sessions rarely work as well as intended. Members are better coming up with
ideas individually. Why? Three reasons
• 1. There may be a tendency for people to social-loaf in brainstorming sessions- not work as
hard
• 2. Members may be hesitant to express ideas that seem silly or not well thought out
• 3. Brainstorming results in production blocking, because members have to wait their turn to
express their ideas
• Why do organizations still do brainstorming?
• The general idea of brainstorming is well known and leads people to believe that it works as
advertised
• There are benefits of brainstorming beyond just generating ideas
• E.g. build morale
• One offshoot of brainstorming that addresses some of its limitations is the nominal group
technique
• Starts off by bringing the team together and outlining the purpose of the meeting →
members have a set period to write down their own ideas individually → share
ideas with team in round-robin fashion → clarify and build on ideas → members

rank order ideas on a card individually and submit to a facilitator→ scores are
tabulated and get the winning idea
• This technique can decrease social loafing and not be hesitant to give ideas and also
judge ideas
DECISION MAKING
• Involves multiple members gather and considering information relevant to their area of
specialization, and then making recommendations to a team leader who is ultimately responsible for
the final decision
• Three factors to effective decision making
• Decision informity which reflects whether members possess adequate information about
their own task responsibilities
• Staff validity which refers to the degree to which members make good recommendations to
the leader
• Hierarchical sensitivity reflects the degree to which the leader effectively weights the
recommendations of the members
• More experienced team tend to make better decisions because they develop an understanding of
the ifoatio that’s eeded ad ho to use it, ad leades deelop a udestadig of hih
members provide the best recommendations
• Team decision may be improved by giving members feedback about the three variables involved in
the decision-making process and not only on the final decision
• E.g. if the members are told that they have to share and consider additional pieces of
information before making recommendation to the leader
• Better for leaders to consider recommendations and make decisions when they are away from the

who may be more assertive or better at articulating and defending their position
BOUNDARY SPANNING
• Involves three types of activities with individual and groups other than those who are considered
part of the team
• Ambassador activities refers to communications that are intended to protect the team, persuade
others to support the team, or obtain important resources for the team
• Members who engage in this tend to be higher up in the organization e.g. senior
management
• Task coordinator activities involve communications that are intended to coordinate task related
issues with people or groups in other functional areas
• Scout activities refers to things team members do to obtain information about technology,
competitors, or the broader marketplace
• The marketing team member who meets with an engineer to seek information about new
materials is engaging in scout activities
TEAMWORK PROCESSES
• Teamwork processes refer to the interpersonal activities that facilitate the accomplishment of the
