Lasswell’s Questions: Expose the Assumptions Inside a Communication Plan

Communication · Executive Insight Brief · 173

Five fields. No place to hide.

Five analytical fields make source, message, channel, audience, and outcomes independently examinable.

Premise

Statements such as “the organization informed employees” conceal nearly every variable that determines whether communication can work. Lasswell’s five questions convert that claim into an audit: who communicated, what was said, through which channel, to which audience, and with what effect. For leaders, the value lies less in the formula’s simplicity than in its refusal to let authority, content, access, audience differences, and outcomes collapse into one activity metric.

The essential model

Lasswell’s 1948 formulation originally organized mass-communication research into analysis of control, content, media, audiences, and effects. As an editorially adapted worksheet, WHO covers authority, credibility, incentives, and production conditions; SAYS WHAT covers claims, evidence, framing, omissions, and requested action; CHANNEL covers reach, persistence, interaction, accessibility, privacy, and constraints; TO WHOM requires meaningful segmentation; and EFFECT requires an operational outcome. A responsible contemporary use may add feedback, intermediaries, algorithms, time, exclusion, unintended consequences, and comparison conditions, while clearly identifying them as extensions.

Why this matters

A new incident-reporting portal illustrates the diagnostic gain. A compliance email may describe the interface but omit whether reports affect performance reviews. Contractors may lack access, supervisors may carry more credibility than the nominal sender, and email opens may be counted as adoption. Lasswell’s fields reveal distinct failures of source, content, channel, audience definition, and outcome measurement. The response is not simply another announcement: it may require supervisor briefings, explicit non-retaliation language, contractor access, opportunities for questions, and evidence of valid reports submitted.

Risks and limits

The questions organize inquiry; they do not establish why an effect occurred. Planned audiences must not be reported as reached audiences, sent content as recalled content, or exposure as changed behavior. The formula can also appear falsely linear because it does not by itself model co-creation, relationships, cultural interpretation, network diffusion, or power. Effects may be delayed, cumulative, unintended, or produced jointly with other interventions, so the evidence design must extend beyond the five labels. Finally, Lasswell’s formula is not the hypodermic-needle or magic-bullet model; later histories constructed that direct-effects association retrospectively.

Executive takeaway

Use the five fields twice: once to document the intended design and again to record what evidence shows actually happened. The gaps between those two versions identify where the communication system failed. Executives should demand a specific answer in every field and reject labels such as “leadership,” “email,” “employees,” or “engagement” when they conceal consequential differences. For material campaigns, the completed worksheet should sit beside the decision record: it makes assumptions visible before launch and prevents retrospective claims of success from substituting for the outcome definition originally approved.

Key questions

• Which communicator has the authority and credibility required for each audience segment, rather than merely formal ownership of the message?
• What essential claim, risk, omission, or requested action must be visible in the message itself?
• Which channel properties are necessary for access, dialogue, persistence, privacy, and redistribution in this case?
• What observable effect will count as success, and what evidence could support a causal interpretation rather than simple exposure?
