Role ambiguity and blurred boundaries: meaning and application

You are asked to 'just' take on an extra task, but nobody says what it involves or how long it takes. This is role ambiguity and blurred boundaries: the boundaries of a role or task are unclear and seem to keep expanding. This article explains its basis, how it differs from related concepts and how to make task boundaries explicit.

Role ambiguity and blurred boundaries describe a situation in which the boundaries of a role or task are unclear and its responsibilities gradually expand, or in which people expect this.

This Neurofactor working concept combines role ambiguity, uncertainty about what is expected of someone, with role creep or job creep: roles that grow without anyone noticing. It also covers the expectation of expansion as a reason to turn down a task.

Role blurring has no single originator; it is a Neurofactor working concept building on three lines of research. A role is the set of expectations attached to a position or task.

The first line is role ambiguity. The book Organizational stress: Studies in role conflict and ambiguity by Kahn, Wolfe, Quinn, Snoek and Rosenthal (1964) gave role ambiguity a central place in research on work stress. Rizzo, House and Lirtzman (1970) developed a questionnaire in which role ambiguity and role conflict were separate factors among managers. In the meta-analysis by Jackson and Schuler (1985), about 85 per cent of the research used those scales. A later meta-analysis by Tubre and Collins (2000) found a negative relationship of r = −.21 between role ambiguity and rated job performance, and a negligible relationship (r = −.07) for role conflict.

The second line concerns expanding roles. Morrison (1994) showed among 317 clerical employees that people differ in what they count as part of their role. In her view, the in-role/extra-role boundary is not clearly defined. Van Dyne and Ellis (2004) used the term job creep in a chapter on extra effort as overfulfilment of obligations, set against organisations asking people to "do more with less". We use role creep as a broader term for a role that grows without new agreements.

The third line concerns role boundaries. Ashforth, Kreiner and Fugate (2000) place roles on a continuum from segmented to integrated. Integration makes transitions smaller but, in their account, increases role blurring, making boundaries harder to create and maintain.

Role conflict and role overload have a separate article on role interference. Scope creep is the project management version of this pattern. Komal et al. (2020) describe it as a frequently cited cause of delays and higher costs in software projects, and found that factors behind scope creep were negatively related to project success.

Role blurring usually develops in small steps, through three mechanisms.

• Incomplete agreements. A task is requested in general terms, such as "being the point of contact", leaving its content implicit: the core of role ambiguity. Newer scales by Bowling et al. (2017) ask, for example, whether someone is sure what is expected of them at work.
• Shifting definitions. What one person sees as extra, another sees as part of the role. Morrison (1994) found these views were related to commitment and social cues, and that people showed extra behaviour more often when they counted it as in-role. Voluntary extra effort can thus become an expectation.
• Pressure to do more. In a study of 245 employees, Bolino, Turnley, Gilstrap and Suazo (2010) found that perceived pressure to be a "good soldier" was associated with more extra-role behaviour, but also with more work–family conflict, job stress and intention to quit. These relationships held after controlling for extra-role behaviour, role overload and hours worked.

These findings are correlational: they show association, not cause.

Role blurring can also weigh in beforehand, when people decide whether to accept a task. Someone who saw a small commitment grow into a permanent responsibility may judge a new request through that lens. Alongside "do I want to do this?", the question becomes "where does this end?".

This is an editorial interpretation. The sources consulted did not measure the expectation of expansion separately; it is a testable hypothesis, not an established mechanism.

The distinction is practical. If rejection stems from expected expansion, a more attractive description helps little and credible boundaries make more sense. If people find the task itself unattractive, clear boundaries will not fix that.

The organisation is not the only one setting boundaries. In the job crafting model of Wrzesniewski and Dutton (2001), people themselves change the task, relational and cognitive boundaries of their work. That latitude can change the trade-off but does not replace clear agreements.

These steps are editorial advice. They have not been studied as a whole but build on role ambiguity and role creep.

1. Describe what the task includes. Name concrete activities and the expected result, not just a job title.
2. Describe what the task does not include. Stating what falls outside the task makes expansion something to discuss, not assume.
3. Set the time investment. Indicate hours per week or month, and what happens if this is structurally exceeded.
4. Agree on an end date or review point. Clarify when the task stops, when it is reviewed and how someone can step down without losing face.
5. Name a contact person. Record who handles new requests and who decides whether they belong to the task.
6. Revisit the agreements when things change. Boundaries lose their value if new tasks are added silently.

In target group research, role blurring can explain resistance to an offer that brings extra responsibility: a new role, a pilot, an ambassador programme or a product that shifts tasks. Then also investigate which boundaries people expect.

Useful questions: what do people think the task involves, what expansion do they expect, what is that based on, and what information would change it? In association research, you can check whether a role or task is mainly linked to concepts such as "unbounded", "always on call" or, conversely, "manageable". Such an association is a clue, not proof of behaviour.

Distinguish uncertainty about content, expected growth and actual scope. Each needs a different solution: information, agreements or a different division of work.

This example is fictitious; no research results are attached to it.

Situation. A volunteer organisation running neighbourhood activities seeks volunteers to become coordinators. Volunteers like their current tasks, but few respond.

Decision question. Why do experienced volunteers decline, and what can the organisation change?

Available information. The call describes the role as "the point of contact for your team". Time, tasks and duration are not mentioned. Informally, some volunteers mention a previous coordinator who "ended up doing everything".

Suitable approach. Short interviews and a questionnaire among volunteers and former coordinators: what does the role involve, what expansion do they expect and what would change their decision? Plus a draft agreement with tasks inside and outside the role, a time indication, a term with a review point and a fixed contact person, shown to some volunteers.

Possible interpretation. If volunteers mainly mention the unbounded scope, that points to role blurring. If they find the tasks unattractive, or lack time regardless of boundaries, the explanation lies elsewhere. A small group does not allow conclusions about all volunteers.

Next step. Decide in advance what to compare, such as reactions to the old and new description, and check after a set period whether the agreements are kept.

• Confusing role blurring with workload. Even a light task can be refused over unclear boundaries; more capacity does not solve that.
• Only changing the description. Unkept agreements confirm the original fear.
• Always treating expansion as a problem. Growth can also offer development; the question is whether it was agreed.
• Relying on self-report alone. Most research on role ambiguity uses questionnaires. Jackson and Schuler (1985) noted that most studies were cross-sectional, without clear causal conclusions. The validity of the classic scales is also debated (Bowling et al., 2017).
• Ignoring context. What counts as a clear boundary differs across paid work, volunteering and organisational cultures; findings do not transfer automatically.
• Using group results as an individual diagnosis. A group-level association does not predict what one person experiences or does.

Role ambiguity and blurred boundaries describe unclear, expanding task boundaries and the expectation that they will keep shifting. The concept builds on research into role ambiguity, job creep and role boundaries. If people turn down a task, check whether the task is the problem or the uncertainty about where it ends. Whether explicit agreements help in your context needs investigating.
