Random assignment, participant choice, and explicit criteria address different constraints; none guarantees a learning outcome on its own. Choose by starting with the planned activity, the session’s constraints, and the information that is genuinely relevant to the decision. This guide offers a way to compare group arrangements without turning questionnaire responses into fixed profiles. Responses can inform the trainer’s choice; they do not make it for them. ## Describe the activity before assigning groups First specify what participants will do together and what they will produce: compare cases, rehearse a conversation, examine a situation, or prepare a decision. An arrangement that fits one activity may not fit another. Then note constraints that can actually limit the options: schedules, session length, group size, case confidentiality, necessary roles, and access needs. Separate requirements from preferences that can be discussed. To choose a procedure, compare [free choice, random assignment, and explicit criteria](/en/blog/the-end-of-random-group-formation-social-psychology-and-algorithms). Fairness of the process and fit between the group and the activity are distinct questions. A rule is easier to explain when you state its criteria, constraints, and how exceptions will be handled. ## What random assignment can and cannot do Random assignment may simplify the process when the constraints allow it. On its own, it does not check whether each group has the cases, roles, or conditions needed for the activity. Depending on the session, a group may bring together very different situations, similar situations, or an uneven mix of roles. These are possibilities to check against the activity, not automatic effects of random assignment. Likewise, sorting only by a declared level may hide differences in context or practice. Before choosing, ask: - Do participants need to work on a shared task or compare several situations? - Must each group include particular roles or cases? - What limits do time, confidentiality, or availability place on the options? - Does a simple rule already meet those constraints? If more than one method remains possible, state why you chose one and what might prompt you to revisit it. ## Collect only information that is useful A pre-course questionnaire can inform a decision when its questions serve a specific purpose and its answers are reviewed with their limits. A 1-to-5 rating, job title, or length of service may not describe the situation the activity will address. Two people selecting the same option may have different experience and needs. Self-reported answers are not a competence test or a motivation diagnosis. They do not establish a person’s personality, learning style, or future performance. Ask only for information that may inform the grouping decision, and avoid personal or confidential details you do not need. Depending on the activity, you might examine: ### 1. The stated goal Why is the person attending now? Do they want to work through a particular situation, prepare a project, or compare a practice? A shared goal may be one criterion to consider, subject to the session’s other constraints. ### 2. The work context Where will the practice be used? Field work, headquarters, a regulated setting, or a team task may involve different constraints. Context can help you decide which cases to compare; it does not determine the composition by itself. ### 3. The reported difficulty Ask what makes the task difficult: missing reference points, a need for practice, unclear instructions, tools, or organisational constraints. This is what the person reports, not an established cause. If people describe different difficulties, check whether the same activity can address them together or whether another format is needed. ### 4. Experience with the task Someone may have observed an activity without practising it, or practised it in another setting. If that distinction matters to the session, ask for an example rather than inferring general ability from a declared level. ### 5. Cases participants are willing to share A case, document, or recent experience may provide material for the session if sharing is appropriate. Ask permission before using an identifiable example and offer a fictional case when confidentiality requires it. ## Compare arrangements against the activity Homogeneous, heterogeneous, and complementary are not quality ratings. They describe possible arrangements to compare with the session’s goal and constraints. ### When to bring similar situations together This may fit when the activity asks participants to compare similar cases, work on a shared foundation, or follow the same progression. Check that useful differences are not lost and that the pace suits the people concerned. ### When to bring different situations together Different contexts may provide cases to examine when the activity is designed for comparison. Allow enough time to make the differences explicit and avoid treating a job-related constraint as an individual preference. ### When to consider complementary contributions For an activity about handoffs or coordination, people in different roles may help the group examine multiple parts of the work. Describe the contributions the exercise needs instead of looking for abstract profiles. Also check that everyone can participate and that no one is given responsibility without the authority to carry it. In each case, state the criterion before assigning groups and check that it matches the work planned. None of these arrangements guarantees participation, useful discussion, or a learning outcome. ## What open-ended answers can add An open response may give you a participant’s own wording, context, or a case that was not included in the options. It may also be brief, incomplete, or focused on something the questionnaire cannot verify. It is not automatically more useful than a scale. One possible prompt, to adapt and pretest, is: > Describe a recent situation at work where you used this topic. What would you like to examine during the session? Review answers with their context and differences. Keep the collected words separate from the trainer’s interpretation and the proposed grouping criterion. If the answers do not settle the decision, ask a follow-up or choose a simpler rule; do not turn uncertainty into a label about the person. The [training placement questionnaire](/en/blog/training-placement-questionnaire-how-to-keep-it-short-without-losing-quality) helps frame self-reported answers; the [actionable questionnaire guide](/en/blog/actionable-questionnaires-start-with-the-decision-not-the-questions) starts from the decision to inform. Neither replaces the trainer’s judgement. ## Fictional example: preparing an exercise on manager interviews Imagine four people attending a session on manager interviews: a manager preparing to conduct annual reviews for the first time, an experienced manager who wants to examine a difficult situation, a project lead who wants to practise wording, and an HR professional who wants to compare internal practices. These descriptions are fictional and reported for illustration; they are not assessed profiles. If the activity is to rehearse a shared conversation, the trainer could give everyone the same scenario and vary preparation time to reflect stated constraints. If the activity is to compare contexts, the trainer could bring different cases together, provided there is enough time to examine them and participants agree to share them. A third option is to have people work on their own case first, then compare approaches in pairs. The questionnaire does not choose among these options. The trainer compares them with the goal, constraints, and available answers, then explains the chosen rule. If information is missing, the trainer can ask a follow-up or use a simple composition. ## Turn responses into a reviewable decision Before assigning groups: 1. write down the activity and intended session outcome without promising a learning effect; 2. list required constraints separately from preferences that can be discussed; 3. collect only necessary information and note what remains unknown; 4. compare the simplest procedure with an option based on explicit criteria; 5. check the selected arrangement against the roles, cases, and conditions planned; 6. keep a record of the criterion and the trainer’s decision. A balance indicator alone cannot establish fit with the activity. Review a proposal against the criteria and adjust it if a real constraint is not met. When the questionnaire is ready for real participants, [Harmate Real Mode](/en/product/real-mode) collects responses. The workflow can help analyse them and propose groups from explicit criteria for the trainer to review and adjust. This proposal does not guarantee participation or a learning outcome. ## Points to check - Do not choose a procedure before describing the activity and its constraints. - Do not use a declared level as the only indicator of experience or competence. - Do not ask for information that has no use in the decision. - Do not treat a short answer as evidence of insincerity or low motivation. - Do not confuse a collected response, an interpretation, and a grouping decision. - Do not promise a learning benefit that group composition alone cannot guarantee. A group arrangement is a preparation decision, not a prediction of what participants will learn. The trainer remains responsible for checking it against the activity and its constraints. ## Conclusion To form training groups, start with the activity, roles, and session constraints. Then choose a procedure—random assignment, participant choice, or explicit criteria—that fits those elements and can be explained to participants. Questionnaire responses may inform the options, but they do not define people’s profiles or guarantee a learning outcome. The trainer makes the decision, explains the criterion, reviews the proposed arrangement, and adjusts it when important information is missing.
