Title: The E-Collaboration Paradox: Evidence from Two Empirical Studies


1
The E-Collaboration ParadoxEvidence from Two
Empirical Studies
  • Ned Kock

2
The e-collaboration paradox
  • Media naturalness proposition
  • The less face-to-face-like a medium is, the more
    obstacles exist for effective communication.
  • Compensatory adaptation proposition
  • Often individuals avoid using unnatural media,
    but, if they decide to use them, those
    individuals compensate for the communication
    obstacles posed by the media.

Study 1
  • An Experimental Study of 20 Process Redesign
    Dyads
  • Analysis Method Used Comparison of Means (ANOVA
    Mann-Whitney U Tests)

4
Participants
  • The research study involved subjects with
    substantial hands-on experience in process
    redesign in the defense sector, recruited from
    management and engineering ranks of a large
    defense contractor.
  • Their ages ranged from 23 to 60, with a mean age
    of 35. Fifty-nine percent of the subjects were
    males.

5
Treatment conditions
  • The subjects were randomly assigned to dyads and
    to communication media conditions.
  • Each dyad completed two similar process
    redesign-related tasks using different
    communication media for each task.
  • Half of the dyads (i.e., 10 dyads) completed one
    of the tasks face-to-face while the other half
    completed the same task electronically.
  • After this, all dyads moved on to the next task,
    using different media than they had used in the
    previous task that is, the dyads previously
    interacting face-to-face now interacted
    electronically and vice-versa.

6
Electronic communication medium
  • A set of Web-based threaded online discussion
    boards created the electronic communication media
    employed in the experiment.
  • The online discussion boards were developed using
    Microsoft Frontpage 2000 and Active Server Pages.
  • They were used in a quasi-synchronous manner
    i.e., they were refreshed at short time
    intervals, creating an online chat-like
    environment where the discussions were threaded.
  • One Web-based online discussion board was created
    for each dyad. All online discussion boards were
    identical.

7
Variables and measures
  • Cognitive effort
  • Measured based on NASAs task load index (a.k.a.
    NASA-TLX) developed by Hart and colleagues (Hart
    and Staveland, 1988).
  • Communication ambiguity
  • Measured based on an instrument previously
    developed and validated by Kock (2001), answered
    on a 1 to 7 Likert-type scale.
  • Message preparation
  • Measured based on an instrument previously
    developed and validated by Kock (2001), answered
    on a 1 to 7 Likert-type scale.

Variables and measures
9
Variables and measures
  • Fluency
  • Measured by counting the number of words
    exchanged by the members of the dyads and
    dividing it by the number of minutes each dyad
    took to complete the task (Kock, 1998).
  • Task outcome quality
  • Measured by comparing the process sketches
    generated by the dyad members with correct
    models (Kock and Murphy, 2001). Two different
    coders generated similarity scores used to
    assess task outcome quality independently.

Results
  • The results suggest that the use of an
    e-collaboration tool, when compared with the
    face-to-face medium, increased perceived
    cognitive effort by about 41, perceived
    communication ambiguity by about 80, and
    perceived message preparation by about 47, while
    at the same time reducing fluency by
    approximately 77.
  • The study also suggests that the use of the
    e-collaboration tool had no significant impact on
    the quality of the outcomes generated by the
    dyads.

13
Conclusion
  • The study supports the e-collaboration paradox
    notion
  • Media naturalness proposition
  • The less face-to-face-like a medium is, the more
    obstacles exist for effective communication
    obsv. cognitive effort, communication ambiguity.
  • Compensatory adaptation proposition
  • Often individuals avoid using unnatural media,
    but, if they decide to use them, those
    individuals compensate for the communication
    obstacles posed by the media obsv. message
    preparation, fluency, task outcomes.

Study 2
  • An Survey Study of 290 New Product Development
    Teams
  • Analysis Method Used Structural Equation
    Modeling (PLS)

15
Participants
  • Contact persons in a variety of technology-based
    companies in the Northeastern USA were selected
    to participate in the study.
  • To be included in this study, each company must
    have developed a product that had been launched
    into the marketplace and commercialized for at
    least six months.
  • Data from 290 new product development projects in
    66 companies were obtained.

16
Research instrument
  • A questionnaire developed based on previous
    research on NPD teams (Kessler and Chakrabarti,
    1999 Lynn et al 2000) was used.
  • All constructs in the study were measured using
    multiple-item scales, which in turn were
    Likert-type scales (0 Strongly Disagree to 10
    Strongly Agree).

Conclusion
  • The study supports the e-collaboration paradox
    notion
  • Media naturalness proposition
  • The use of electronic communication (as opposed
    to the face-to-face medium) induces procedural
    structuring, which suggests an attempt (through
    procedural structuring) to compensate for media
    obstacles.
  • Compensatory adaptation proposition
  • Procedural structuring has a stronger effect on
    task outcome variables than electronic
    communication use, as individuals compensate (or
    perhaps overcompensate) for the communication
    obstacles posed by the electronic communication
    media.

22
Implications
  • Development of e-collaboration tools in
    situations where compensatory adaptation is
  • Desirable and unhindered
  • Desirable but hindered (e.g., cognitive fatigue
    situations)
  • Undesirable (e.g., entertainment-related B2C
    situations)
