Project loafing in Projects

Revision as of 21:47, 20 February 2022

Collective work, collaboration, and the exchange between individuals are inherent in our society. Those relations are important in all aspects of life: social and professional; and at an early age, people learn the importance of teamwork. Most companies and institutions rely on teamwork and team effort. Most of the time, this strategy is highly successful, but why do so many people don’t like group working? One of the biggest reasons could be a phenomenon called social loafing.

Social loafing is the tendency of people to make less effort when working in a group than when working individually (Latane et al., 1979). There are many reasons why this happens, one example is that individuals tend to loaf when their performance cannot be evaluated (Harkins, 1987). Many experiments were made during the past decades to investigate why, and in which circumstances social loafing occurs. It is a big challenge to project leaders to avoid this behavior in their teams. How to keep a team motivated? How to make people work collectively keeping up the high efficiency and quality of the work delivered?

The article will go through some of the experiments made to investigate social loafing, such as the simple rope-pulling task made by Ringelmann in 1913, to a more complex task that requires concentration from the participants; probable causes why individuals don’t give their best when working in a group; and to conclude, some measurements and actions to prevent social loafing to occur. Avoiding social loafing has considerable importance to project management because this tendency can be detrimental to a project’s success.

1. Social loafing

Social loafing is defined as the reduction of effort and motivation of individuals when working collectively, compared to working by themselves or in coactive work (Williams et al. 1993). Coactive work means people having individual tasks within a team setting.

Our society is based on group work: governments, organizations, sports, etc. And the success of the tasks performed by a group depends on many different factors. A project is usually composed of multiple people with different expertise, therefore good group and project management are crucial, and identifying possible problems, such as social loafing, is extremely important.

Many psychologists and researchers realized different experiments to understand why people tend to loaf when working in groups, and what could be done better to improve the overall performance of a group. For Latané, Williams, and Harkins, social loafing could be considered a social “disease” for having “negative consequences for individuals, social institutions, and societies” (Latane et al. 1979).

1.1. Experiments tasks inputs

Those experiments involved tasks with different inputs that can be classified as (Williams et al. 1993):

• Types of effort necessary: physical, cognitive, perceptual, or evaluative

• Difficulty levels: simple or complex

• Criteria of performance: maximizing or optimizing results

• Task value for the subjects: high or low

• Group value: close friends, teammates, group cohesiveness, etc.

• The expectation of group members performance: high or low

• Group or Individual evaluation: opportunity to get feedback and be individually evaluated

• Task uniqueness: if all subjects had the same task or different one

• Group size

• Age of the subjects

• Gender of the subjects

• Status of the subjects: young students, undergraduate students, or companies’ employees

• Subjects’ culture: Eastern or Western

1.2. Investigating social loafing: examples of experiments

A. Pulling-rope experiment

In 1913, a German psychologist called Ringelmann made an experiment involving rope pulling. This experiment was never published but it was described and used in many papers to explain social loafing. The experiment consisted of asking workers to pull a rope as hard they could, and the force was measured by a machine that could tell how many kilograms of pressure they were making when pulling the rope. They expected that the group force would be equivalent to the sum of the individual efforts, but the result was completely different. As the group members increased, the force made by each worker decreased (Latane et al. 1979).

In 1972, Steiner proposed two possible causes of the lower individual performance in Ringelmann’s experiment: loss of motivation or coordination loss (Williams et al. 1993).

B. Hand clapping and shouting loud

First experiment:

Latané, Williams, and Harkins proposed a new experiment, they evaluated how much sound pressure a group of undergraduate students made when standing alone, in pairs, in groups of 4 and 6. The students were placed in a soundproof room, with a General Radio sound-level meter. The results were similar to Ringelmann’s experiment, as the group increased, the individual performance decreased (Latane et al. 1979).

Second experiment - Coordination Loss or Reduced Effort:

A second experiment using the same task of clapping and cheering was made but with the difference that the participants couldn’t see each other. They were given a blindfold and headsets and asked to do the same thing as the first experiment: cheer and clap as loud as they could. They were told that either one other person will shout with him, or all six were shouting together. On the headset, a recording of people cheering was played so the participants could not evaluate their performance. These actions were made to analyze if the performance drop was due to lack of effort or if it was coordination loss. The procedure change was not enough to eliminate their teamwork feeling, or social loafing (Latane et al. 1979).

Both experiments, with different methodology, presented the same result: as the group increased, there was a decrease of sound pressure produced per person (Latane et al. 1979).

C. Brainstorming and Vigilance task

First experiment - Brainstorming (maximizing results):

In this experiment performed by Harkins (1987), the participants were divided into singles and pairs. They were instructed to brainstorm as many different uses they could find for a given object (maximizing). Some participants were told that their performances could be evaluated, that everyone had the same object, and others were told that their performances could not be evaluated since it was given a unique object.

The results showed that when evaluated, the participants tend to have a better performance in both single and coaction conditions. According to the analysis made by Harkins (1987), the participants in the coaction/pooled output condition felt that their individual performance could not be measured (evaluated), therefore had almost the same result as the coaction/no evaluation condition.

Second experiment - Vigilance (optimizing results):

To investigate different criteria of performance, the participants were asked to perform a task involving optimizing the results. The participants were also divided into individual and pairs (coaction), and the task was to report when random signals occurred on a TV screen. Some were told that a computer will track their performance, while others were told that the computer is not working properly, simulating the scenario of evaluation and no evaluation (Harkins 1987).

The results showed that in both experiments evaluation has a great impact on the performance of the participants. On the brainstorming task, they suggested more uses for the given object, and on the vigilance task, they made fewer mistakes. Harkins discusses in the journal about Social Loafing and Social Facilitation, that a plausible reason why coaction (pairs) performance outcome the single’s performance is that working together gave the participants a possibility of self-evaluation, by comparing their performance with his partner (Harkins 1987).

D. Integrative Model of individual Effort on Collective Tasks (CEM)

In 1993, Karau and Williams proposed a method that could predict what key attributes are more valuable in a group, and what would motivate more the individuals in this group. The CEM analyzed and crossed different experiments involving social loafing (Williams et al. 1993).

Conclusions of CEM (Williams et al. 1993):

• Identifiability only augmented the effort in tasks when individuals thought it was not important or relevant, but in meaningful tasks, it showed no effect at all or even a decrease of effort.
• The individual’s gender, culture, and preferences are very relevant to the group outcome.
• When individual behaviors are dispensable to the outcome of the project, it is less likely to have a high level of effort.
• Good communication within the group members showed to be positive to collective effort when showing the importance of the task, but negative talk has the opposite effect.
• Group structure and members’ roles are important to the group effort. Being seen as important in the group, contribute to enhancing the effort made.
