Activity vs hierarchy – influence in ESN

In a recent study we looked into the ways in which users gain influence in Enterprise Social Networks: Is it through their position in the organisational hierarchy (formal influence) or by way of being an active contributor to the network (informal influence)?

We measured influence through the ability to garner responses to one’s messages posted into the network. In other words, does my ability to convince others in the network to reply to my messages depend on what my formal role is or does it depend on whether or not I am an active contributor myself.

Study approach

For this study we had access to the ESN data of Deloitte Australia, who were also able to provide data on the formal role and hierarchy position of about 65% of their users. All data was anonymous; users where only identified through an ID.

We operationalised three separate dependent variables: reply received yes/no, number of replies received, and time lag until first reply received.

We then hypothesized that 1) the higher one’s position, the more elikely they are to receive a reply, the more likely they are to receive more replies, and faster. 2) The same hypotheses were formulated for activity: The more active someone is in the network, the more likely they are to receive more replies, and faster.

After statistical testing, our results confirm both forms of influence. Interestingly however, the informal influence of communication activity is the much stronger effect. 

Hierarchy in ESN matters – but not much

On average, a user’s hierarchical level has a statistically significant influence, but this influence is so small that it does not to matter in day-to-day practice. For example, a user who outranks another user by one level in the hierarchy is able to elicit on average 1% more responses.

Interestingly, messages from users in higher positions elicit slightly slower responses on average. We reason that people might need more time to formulate an adequate answer or take more care in editing replies to users in higher positions. The reason might be the perceived social distance between sender and receiver.

Being active matters most

The strongest finding from our study is that a user’s communication behaviour has a much stronger effect on response behaviour than their hierarchical position. Our findings thus confirm the long-standing argument put forward by proponents of ESN that the social networks that emerge on ESN platforms can lead to a re-balancing of influence in organisations – away from formal hierarchy toward recognising user contributions.

In other words, people who have something to contribute will be recognised by the organisational community and be able to derive influence from their standing in the community, even if they do not sit in high-level hierarchical positions.

At the same time, our findings show that formal hierarchy does not lose its influence entirely, as both formal and informal hierarchy show up in our data. We also need to point out that the results operate on averages, it does not mean that single individuals will not derive significant ESN influence from their position on the org chart.

Yet, being the first of its kind, our study demonstrates that prolific knowledge workers might benefit from their contributions to and investment into the ESN, because they are able to draw on the network for contributions, not having to rely merely on information flows along the organisational hierarchy. We are conducting further research to unpack these effects with more detailed analyses. I will post more results in due course.

  1. So true, being active does matter the most. We found at Mumba Cloud that true adoption depends on the actual user’s day to day engagement in tasks, projects and overall discussions. Objectives and Goals need to be discussed before hand and tackled one step at a time in order to increase the engagement in the implementation process.

    Overall ESN’s improve productivity, increase task efficiency, boost communication, reduce costs and build a healthy culture which has endless benefits to any organization.

    Thanks for the great insight Kai
