In-house training or open class: how companies can choose the right format

Choosing between in-house training and an open class is not simply a question of where a course takes place. The more useful starting point is the capability the company wants to develop, who needs that capability and how closely the learning experience must reflect the organisation’s operating context.

For HR and L&D Managers, Supply Chain Directors and Operations Managers, the format therefore becomes part of the training decision itself. An open class may be the most efficient way to develop one or a few professionals. In-house training may be more appropriate when a team needs to build a common language, work toward shared objectives or connect learning more closely with company priorities. Live webinars can add another option when geographical distribution or scheduling makes classroom delivery less practical.

There is no format that is inherently better in every situation. The stronger choice is the one that matches the learning objective while keeping budget, calendar, participation and required customisation under control.

Why the training format should follow the business objective

Companies sometimes begin with a logistical question: should employees attend an existing course, or should the programme be brought inside the organisation?

That question is useful, but it comes too early.

The first issue is what should be different after the training. If the objective is to strengthen the expertise of one planner, buyer or Supply Chain Manager, the organisation is dealing primarily with an individual development need. If several people need to adopt the same concepts, terminology or management approach, the requirement becomes organisational as well as individual.

This distinction matters because training formats create different learning conditions.

An open class places individual participants within an established programme and gives them the opportunity to interact with professionals who may come from other organisations and industries. In-house training brings the learning experience into the company context and can make it easier to coordinate a group around shared priorities. Live online formats can preserve instructor-led interaction while reducing some of the geographical constraints associated with classroom participation.

The delivery mode should therefore be considered after the learning objective has been clarified, not before.

When in-house training is the better fit for a team

In-house training becomes particularly relevant when the need involves more than transferring knowledge to individual employees.

A company may, for example, want several people working across Supply Chain or Operations to develop a consistent understanding of planning principles, processes or management practices. In that situation, sending participants separately to different course editions may provide useful individual learning but does not automatically create alignment across the team.

A dedicated programme can instead give participants a common reference point and create the conditions for applying what has been learned to shared operational priorities.

Another potential advantage is the possibility of extending the learning journey beyond the classroom. An in-house programme can be connected to a post-training improvement project focused on selected processes or KPIs. Participants can then apply the methods and concepts covered during the course to a real business context, turning training into a structured opportunity to test, consolidate and transfer learning into day-to-day operations.

This approach can also strengthen the return on the training investment. Rather than evaluating the programme only in terms of attendance or knowledge acquisition, the company can link it to concrete improvement objectives and observe how effectively the learning is translated into operational practice.

This does not mean that every team should be trained in-house. The value depends on the number and profile of participants, the similarity of their learning needs, the importance of connecting the programme with the organisation’s operating environment and whether there is a meaningful opportunity to apply the learning after the course.

Team size and the need for a common learning path

The number of participants is one of the first practical variables to examine, but it should not be treated as an isolated threshold.

Two organisations with the same number of employees to train may have very different needs. One may have several professionals performing similar roles and requiring the same competence development. Another may be grouping people from unrelated functions whose learning objectives overlap only partially.

The second situation does not automatically become suitable for in-house delivery simply because enough participants are available.

The more important question is whether there is a meaningful common learning objective. When there is, a shared programme can support consistent terminology, concepts and methods across the group. For Operations and Supply Chain teams, where decisions frequently cross functional boundaries, that consistency can be particularly relevant.

When learning needs remain predominantly individual, an open class may preserve greater flexibility.

Customisation, scheduling and company-specific requirements

Customisation is another reason companies consider in-house training, but it is useful to define what customisation actually means before making it a decisive criterion.

A company may require adjustments to examples, emphasis, scheduling or the way certain topics are connected with its professional context. In other cases, the organisation may simply need a well-established programme delivered to a dedicated group.

These are different requirements.

The first calls for a closer examination of how far the training needs to reflect company-specific situations. The second is primarily about organising participation and creating a shared learning environment.

A further level of customisation can concern what happens after the formal training. When the programme is linked to an improvement project, participants can work on selected processes, performance indicators or operational issues with the explicit objective of applying the concepts covered during the course. This creates a stronger connection between learning and execution and makes it easier to assess whether the programme is generating value beyond the classroom.

Scheduling can also influence the decision. Bringing participants into the same programme may make coordination easier in some organisations, while in others removing several people from operational responsibilities at the same time may create unnecessary disruption.

In-house delivery gives the company greater control over some of these variables, but that control is useful only when it supports the learning objective.

When an open class is more effective for individual development

An open class is often the more straightforward option when the training requirement concerns one professional or a small number of employees.

Instead of designing or coordinating a dedicated company programme, participants can join an established course and follow its existing structure. For organisations managing different development needs across several functions, this can provide valuable flexibility.

An employee working in planning may require one programme, while a colleague in procurement or logistics may need another. Treating these as separate development paths can be more sensible than attempting to combine them into a single corporate initiative.

Open training should therefore not be viewed as a reduced version of in-house learning. It addresses a different type of requirement.

Training one or a few professionals without creating a dedicated programme

When only a limited number of people need a specific competence, the economics and organisation of a dedicated programme may be difficult to justify.

An open class allows the company to address the requirement without waiting for a broader group to emerge. This can be important when a competence gap is linked to an employee’s current role, a new responsibility or a defined professional development plan.

The same logic applies when employees need different courses. A company does not necessarily benefit from standardising every training decision across the organisation. Where roles and development objectives differ, individual course selection can be the more precise approach.

For HR and L&D teams, open classes can therefore support targeted development without turning every learning requirement into a company-wide project.

The value of learning alongside professionals from other organisations

Open classes can also create a learning dynamic that is difficult to reproduce in a programme reserved for one company.

Participants are exposed to questions, interpretations and professional situations from outside their own organisation. For experienced managers in particular, this can provide useful perspective by showing how similar Supply Chain or Operations issues are approached in different environments.

External comparison should not be confused with copying another company’s methods. Its value lies in challenging assumptions and widening the frame through which participants interpret their own work.

For some learning objectives, that cross-company perspective may be as valuable as contextualisation.

In-house training vs open class: a practical comparison

The two formats answer different priorities. Comparing them across a small number of practical criteria makes the trade-offs easier to see.

The table should not be read as a scorecard. A characteristic that is an advantage in one situation can be neutral or even undesirable in another.

Cross-company interaction, for example, may be valuable for a manager seeking broader professional perspectives. A company trying to align an entire planning team around the same working principles may place greater value on internal consistency instead.

The possibility of connecting an in-house programme with a post-training improvement project adds another consideration. Where the company has suitable processes or KPIs on which participants can apply the learning, training can become part of a broader capability-building initiative rather than remain an isolated educational intervention.

The criteria that should determine the training format

A useful format decision can usually be reduced to a few questions.

Who needs the training? What must participants be able to understand or do afterwards? Is the objective individual development or shared capability building? How much company-specific context is genuinely required? What operational constraints affect attendance? Is there also an opportunity to apply the learning to specific processes or performance indicators after the programme?

Answering these questions makes the comparison substantially clearer.

Learning objectives and expected organisational impact

The learning objective should carry more weight than the delivery preference.

If the desired outcome is the development of one professional, the organisation should evaluate the programme primarily on its relevance to that person’s role and competence requirements.

If the desired outcome is broader — for example, creating shared knowledge within an Operations team — the organisation also needs to consider how learning will transfer across participants.

This distinction between individual competence and collective capability is central.

A group of individually well-trained professionals does not automatically operate with a shared framework. Conversely, a common training experience is not necessarily efficient when participants have substantially different roles and knowledge gaps.

The format needs to follow the type of impact expected.

For in-house programmes, the expected impact can also extend beyond competence development. Where appropriate, a post-training project can provide a structured environment in which the team applies new concepts to an actual process, operational issue or KPI. This makes the transfer of learning visible and gives the organisation a more concrete basis for evaluating the effectiveness of the training.

Budget, calendar and operational constraints

Budget is important, but comparing only the visible cost of the course can lead to a weak decision.

Training also involves working time, travel where applicable, scheduling and the operational consequences of employee absence. For team-based programmes, coordination effort may also be relevant.

The appropriate comparison is therefore not simply between the price of an open-class seat and the cost of an in-house programme. Companies need to assess the complete use of resources associated with each option.

The potential for post-training application should also be included in this evaluation. If an in-house programme supports a structured improvement initiative, part of its value may come from helping participants translate learning into operational changes rather than from the classroom experience alone.

This does not guarantee a predefined financial return. It does, however, create a clearer connection between training expenditure, application of new competencies and observable business outcomes.

Calendar constraints deserve the same treatment.

An open class may offer a convenient scheduled date for one participant. For several employees, those dates may not align with operational requirements. An in-house programme can give greater scheduling control, but concentrating participants into the same period may create other constraints.

There is no universal solution. The decision depends on how the format interacts with the company’s actual operating calendar.

The level of customisation the programme actually requires

Customisation is frequently cited as a reason for choosing in-house training, but not every organisation needs it to the same degree.

Some companies require training to connect explicitly with internal processes, terminology or specific management challenges. Others mainly need several employees to follow the same high-quality programme together.

Before choosing the format, it is useful to distinguish between different needs: a dedicated audience, scheduling flexibility, content customisation and post-training application.

They are related, but they are not identical.

A company may need a dedicated edition without substantially changing the programme. Another may value content adaptation but have only a few participants. A third may find that a standard open class already covers the required competence sufficiently well.

In some cases, the strongest reason for choosing in-house training may not be additional classroom customisation at all. It may be the opportunity to use the course as the starting point for a structured improvement project, allowing participants to apply what they have learned to selected processes or KPIs.

Defining the requirement precisely prevents “customisation” from becoming a generic justification for a more complex training solution.

Where live webinars and other flexible formats fit

The choice does not always need to be reduced to classroom-based in-house training versus an open class.

Live webinars and other instructor-led online formats can be relevant when participants are distributed across locations, travel is difficult to coordinate or the organisation wants to maintain interaction without bringing everyone into the same physical classroom.

For international or multi-site teams, this can materially change the decision.

A virtual format can support a shared learning experience while avoiding some logistical constraints. At the same time, the company should evaluate whether the subject, learning objectives and planned interaction are well suited to online delivery.

The key principle remains the same: delivery technology should support the learning objective rather than determine it.

Online does not automatically mean more flexible in every respect, just as classroom training does not automatically mean more effective. The quality of the fit depends on how participants need to engage with the content, the instructor and one another.

Should the company train individuals or the whole team?

A practical way to reach a decision is to begin with the unit of change.

If the capability gap belongs mainly to one person, individual training is usually the natural starting point. If the gap affects how several people coordinate decisions, exchange information or apply a common methodology, the team becomes the more relevant unit.

Consider a Supply Chain function in which one manager needs deeper knowledge in a particular discipline. Sending that person to an appropriate open programme may address the requirement directly.

Now consider a team in which planners, managers and other stakeholders need a consistent understanding of the same planning approach. The training objective is no longer limited to individual expertise. It includes alignment.

In that case, a shared training experience deserves stronger consideration.

The case for in-house training can become stronger still when the organisation wants participants to move from a shared understanding to shared application. A post-training project focused on an agreed process or set of KPIs can give the team a practical environment in which to use the concepts learned, compare interpretations and translate training into operational action.

Companies should also avoid creating an artificial either-or decision. Development plans can combine formats. Selected professionals may attend open programmes for specialist development, while broader teams receive dedicated training when a shared capability is required.

The objective is not to standardise the training format. It is to create coherence between the development need and the way training is delivered.

Frequently asked questions about corporate training formats

How many participants make in-house training worth considering?

There is no universal number that determines when in-house training becomes the better option. Team size matters, but it needs to be evaluated together with learning objectives, scheduling, budget and the degree to which participants share the same development need.

A smaller group with a strong common requirement may have a better case for dedicated training than a larger but highly heterogeneous audience. The opportunity to connect the programme with a practical improvement project can also influence the decision, because the value of in-house training may extend beyond the number of classroom participants.

Can an open class still support company-wide development goals?

Yes, particularly when company-wide development is built through several individual learning paths rather than a single shared intervention.

Open classes can be appropriate when employees require different specialist competencies or need training at different times. Where the objective is to create a common framework across a team, however, the organisation should also assess whether separate attendance provides enough alignment.

Is in-house training always more customised than an open class?

Not necessarily.

In-house describes how and for whom the training is organised; it does not by itself define the degree of content adaptation. Companies should clarify whether they need a dedicated group, a different schedule, contextualised examples, substantial programme customisation or a structured post-training application project.

Treating these as separate requirements makes supplier and format evaluation more precise.

Can in-house training improve the ROI of corporate training?

It can create favourable conditions for a stronger return on the training investment, particularly when learning is followed by structured application.

For example, participants may work on a selected process, operational problem or KPI after the course, using the methods learned during training. This makes it possible to connect competence development with practical implementation and to evaluate whether the programme is contributing to observable improvements.

The effect should not be assumed in advance: ROI depends on the quality of the training, the relevance of the selected improvement project, management support and the organisation’s ability to implement what participants have learned.

When is a live webinar preferable to classroom training?

A live webinar can be particularly relevant when participants are located in different places, travel would create unnecessary complexity or a company wants instructor-led learning without organising a physical classroom.

Its suitability still depends on the topic, the required interaction and the learning objectives. The choice should therefore be made on educational as well as logistical grounds.

Choosing the format around the capability the company needs to build

The most useful training-format decision starts with the capability the organisation wants to create.

Open classes provide flexibility for individual development and can expose participants to professional perspectives beyond their own company. In-house training becomes particularly relevant when several people need a common learning experience, stronger organisational alignment or closer connection with shared requirements. It can also create the conditions for a post-training improvement project, allowing participants to apply new methods to selected processes or KPIs and making the transfer from learning to operational practice more visible.

Live webinars add another flexible alternative where location and scheduling would otherwise limit participation.

For companies evaluating professional training in Supply Chain and Operations Management, the decision is therefore less about identifying the “best” format and more about defining the right relationship between participants, learning objectives, company context, operational constraints and the expected level of application after the course.

Once those variables are clear, the format becomes easier to choose — and the risk of investing in training that is convenient to organise but poorly matched to the real development need becomes significantly lower.
