Information Overload and Role-Based Access

In 2023, a summary in Harvard Business Review reported that 27% of surveyed employees felt at least somewhat overloaded by organizational information and meetings. The survey, conducted by Gartner, reflected a workplace in which constant updates and messages had become the norm rather than the exception.

At the same time, many non-executive employees now see a broad range of financial, operational, and strategic information through digital tools and internal platforms. Yet the formal authority to change budgets, policies, or risk positions often remains concentrated in a smaller leadership group.

This gap between what employees know and what they can change shapes how information overload is experienced. Visibility without corresponding authority can turn transparency into a source of strain rather than a source of control.

Information Overload by the Numbers

Information overload describes a situation in which the volume or complexity of incoming information exceeds a person’s practical ability to process and use it. The authors of the 2023 Harvard Business Review article characterize modern organizations as operating on an "always-on" communication model.

They note that overload can contribute to disengagement and weaker decision quality. In that analysis, employees who reported overload described an environment with many channels, frequent meetings, and a sense that they could not keep up with everything they received.

When a large portion of the workday is consumed by reading, listening, and reacting to internal updates, less time remains for focused execution.

A 2023 systematic review on PubMed Central synthesizes evidence on information overload across multiple studies. The review reports that overload is positively associated with strain and burnout and that it is linked with various health complaints and lower job satisfaction. The review notes that “information overload was cited as one of the most frequent stressors by 22.5% of respondents in a representative German sample (Meyer et al., 2021).”

The same review highlights evidence that overload is associated with performance losses and lower decision quality. When workers face too many inputs, disruptions, and interruptions, they may struggle to distinguish relevant details from peripheral updates in the time available.

A 2025 study on digital work, also published on PubMed Central, focuses on the side effects of digitalization for employees. The authors report that information overload created by digital tools exacerbates role conflict.

Excessive information input contributes to cognitive overload, which further intensifies role conflict and job burnout. Together, these results link high information volume with both psychological strain and degraded work outcomes.

They also indicate that digitalization, if unmanaged, can increase the risk that employees will face overlapping or conflicting demands while trying to keep pace with continuous flows of data.

When Awareness Outpaces Authority

Organizational transparency often expands through shared dashboards, open channels, and broad access to planning documents. Non-executive employees can see more of the organization’s risks, tradeoffs, and delays than in earlier eras of tightly controlled information.

However, the formal authority to change course in areas such as budgeting, compliance, or strategic direction typically remains limited to managers and executives. For employees who observe problems but cannot meaningfully influence them, awareness can coexist with a sustained sense of powerlessness.

That dynamic can amplify the psychological costs documented in the research on overload. When employees read about risks or inefficiencies without clear avenues to act, the information adds concern but not necessarily agency. This can contribute to frustration and lowered morale over time.

The 2025 blog on information overload from LumApps describes a related operational pattern. The article notes that many workers spend significant time searching for documents, messages, or contacts across fragmented repositories instead of applying information directly to their tasks. As the LumApps piece summarizes it, “Employees are spending valuable time hunting for what they need – time that could be better spent on actual work. This impacts productivity, innovation, and even employee satisfaction.”

In such environments, information is both abundant and hard to use. Employees may feel responsible for knowing as much as possible about organizational activity, while also lacking clarity on which issues they are expected to own and which remain outside their remit.

When everyone can see a risk but no individual is explicitly assigned to manage it, accountability can diffuse. This diffusion can leave non-executive staff feeling exposed to bad outcomes while being unsure whether their role includes the authority or obligation to intervene.

Over time, broad but unstructured access may also affect trust. If visibility into decisions does not come with meaningful opportunities to contribute, employees may question whether transparency is intended to enable them or simply to keep them informed without real influence.

How the Need-to-Know Principle Works

Information-security practice offers a different model for structuring access. The need-to-know principle, summarized by DataSunrise, states that people should only access the information necessary for them to perform their job well.

In this approach, the default is not that everyone can see everything. Instead, access is granted because a specific task or role requires particular data, and other users do not receive that access, even if they are technically capable of viewing the information.

The U.S. Centers for Medicare & Medicaid Services applies a related standard in its security guidance. The CMS access-control manual states that system access must be based on the principle of least privilege.

This means accounts should be provisioned with no more access than is required to fulfill job duties, and it notes that limiting access to those with a documented need to know helps protect sensitive information.

Role-based access control, commonly abbreviated as RBAC, translates these principles into a structured model. In their 1992 paper for the National Institute of Standards and Technology, David Ferraiolo and David Kuhn describe role-based access controls that assign permissions to defined roles rather than to individual users.

Under RBAC, a system administrator defines roles such as "regional sales analyst" or "claims reviewer" and associates each role with explicit permissions across systems and datasets. Individual employees are then mapped to one or more roles, and changes in responsibility are reflected by adjusting role assignments.

From the perspective of information overload, this structure narrows the scope of information that appears in a typical workday. When dashboards, shared drives, and channels reflect the domains tied to a person’s responsibilities, employees can spend more time interpreting a focused set of inputs.

This alignment also clarifies authority. If access is granted because a role is accountable for a process or metric, the people in that role are less likely to receive streams of data about areas they cannot change JerdenThey are more likely to see information that they are actually expected to act on.

Designing Exceptions for Collaboration

Some positions require a broader view of organizational activity to coordinate work across boundaries. Program managers, integration engineers, and other cross-department liaisons often need insight into multiple systems or teams. This insight helps them align schedules, manage dependencies, and surface conflicts early. These roles, sometimes described informally as "glue" positions, present a design challenge.

Giving them universal access increases the risk of overload and exposure to issues that they cannot address, while limiting them too narrowly can obstruct coordination and delay problem solving.

Role-based access control allows organizations to address this by defining liaison roles with carefully chosen privileges across several domains. Instead of a blanket entitlement, these roles can receive read or edit rights only where cross-team coordination genuinely depends on shared information.

Guidance from CMS highlights the importance of auditing and monitoring how privileged accounts are used. The access-control documentation emphasizes that systems should log actions such as account creation, modification, and removal.

Organizations should be able to trace administrative actions for review. By applying similar logging and review to liaison roles, organizations can support broader visibility where needed while retaining accountability.

If sensitive information appears in a shared space or is used in a questionable way, audit trails make it easier to understand what happened and adjust permissions accordingly.

The research on information overload suggests that even employees who are expected to handle complex, cross-cutting information remain vulnerable to cognitive strain when exposure grows without limit. Keeping the scope of what these employees see close to what they are expected to coordinate helps balance coordination benefits with the mental demands of their role.

Operational Steps to Reduce Overload

Addressing overload linked to broad access begins with understanding where information resides. Organizations can start by cataloging their major knowledge repositories, including shared drives, collaboration platforms, reporting tools, and ticketing systems.

They should also assign a clear business owner to each repository. This inventory often reveals channels or storage locations that no longer have active owners but still produce notifications or serve as de facto archives.

Clarifying which teams are responsible for each repository is a prerequisite for aligning access policies with actual work. The next step is to describe roles in clear operational terms and map each role to the repositories and data types that are essential for its core responsibilities. For example, a quality engineer may need detailed defect reports and test logs, but not the full set of financial forecasts that a treasury analyst uses.

Implementing this mapping within technical systems is where models such as the RBAC framework described by NIST become practical. Identity and access-management tools can associate users with roles and apply consistent permissions across multiple applications.

Policy is only part of the solution. Communication practices also shape overload, since many systems allow users to subscribe themselves to channels, alerts, or reports beyond those technically required for their job.

Clear norms about which spaces are intended for broad awareness and which are restricted to specific roles help prevent informal permission creep. Organizations can monitor indicators that overload is rising, such as the proportion of time spent in meetings or the number of communication channels employees follow.

The academic literature’s association between overload, strain, and lower job satisfaction provides a basis for treating these metrics as early warning signs rather than isolated complaints.

Regular reviews of exceptions are important as responsibilities evolve. Liaison roles or project-based access grants that were appropriate during a merger, product launch, or crisis response may be unnecessary once the work transitions to a steady state.

What Balanced Access Looks Like

A balanced access model seeks to combine targeted transparency with focused responsibility. Instead of providing real-time financial dashboards to all employees, organizations can share quarterly summaries and narratives with most staff.

Finance and risk teams that directly manage financial figures would retain access to granular transaction feeds and scenario models. Project-management tools can present only the tasks, risks, and dependencies that are relevant to a contributor’s current work.

Additional context can be made available on request rather than pushed by default. This keeps individuals aware of key interfaces without requiring them to track every initiative that the tool happens to contain.

Risk and compliance information can follow a similar pattern. Specialists may need detailed evidence, control mappings, and incident logs, while frontline teams benefit more from clear guidance on the specific procedures and checks they are expected to perform.

Structuring access in this way reduces the gap between knowledge and influence. Employees see more of the information for which they are actually accountable and less of the information that they could not act on.

This can support both clearer ownership and more confident decision making. Although storage costs continue to fall and collaboration tools continue to multiply, the evidence on information overload suggests that unbounded visibility has measurable human and organizational costs.

By aligning data flows with role-based authority and documented need, organizations can preserve transparency where it supports shared goals while limiting exposure that primarily produces stress, confusion, or a sense of powerlessness.
