Multi-Project Management: How to Manage Multiple Projects Simultaneously

Categories: PM Knowledge|Published On: 17. April 2026|By Beate Schulte|

In many organisations today, numerous projects are running simultaneously. New projects are launched, existing ones evolve, and priorities shift. Whilst project management provides the framework for individual initiatives, a different question arises at the organisational level: how do companies maintain control over the interplay of all ongoing projects? This is where multi-project management comes in. It describes the active, cross-project management of priorities, resources and decisions during day-to-day operations. The aim is not only to ensure transparency across projects, but also to be able to intervene in the project landscape in a targeted manner – even when conditions change at short notice. Whilst project management provides the framework for individual projects, the focus here is on managing their interaction during day-to-day operations.

Multi-project management involves the cross-project management of several parallel projects within an organisation. It encompasses the adjustment of priorities, the reallocation of resources and the management of deadlines during day-to-day operations. The aim is to resolve conflicting objectives between projects and to actively manage the overall project portfolio.

In practice, multi-project management is particularly evident in specific decision-making situations: for example, when several projects are simultaneously accessing the same resources, short-term shifts in priorities become necessary, or dependencies between projects require adjustments.

Typically, decisions cannot be made in isolation. Any change in one project has an impact on other projects – making precisely these interactions transparent and actively managing them is at the heart of multi-project management.

The challenges of multi-project management include:

Resource bottlenecks caused by overlapping project requirements
Conflicts of interest between strategically important and operationally urgent projects
A lack of prioritisation at portfolio level
Insufficient transparency regarding dependencies between projects

These challenges demonstrate that multi-project management is not merely a matter of reporting, but an ongoing management responsibility.

Why multi-project management is more than just keeping track of things

Transparency is a prerequisite – but management is a lot more than that

An overview of all projects forms the basis of any cross-project management. Project lists, status reports and portfolio overviews provide transparency regarding ongoing initiatives, deadlines and budgets. Yet this transparency alone does not bring about change. In many companies, multi-project management ends precisely at this point: you know which projects are running and where they stand. What is missing, however, is the systematic translation of this information into decisions. Transparency answers the question ‘What is happening?’, but not ‘What does this mean for other projects?’ or ‘Where do we need to intervene?’. Control begins where transparency becomes the basis for cross-project decisions.

Project management begins where decisions about projects are made

The crux of effective management of multiple projects lies in decisions that affect several initiatives simultaneously. These include questions such as: Which project takes priority when resources are scarce? Which initiatives must be postponed to make way for strategically more important projects? Where is intervention necessary to mitigate risks affecting multiple projects simultaneously?

Such decisions go beyond the remit of individual project managers. They involve conflicting objectives between projects and require a broader perspective on the entire project landscape.

Operational levers for multi-project management in day-to-day project work

Cross-project management is not reflected in concept papers, but in concrete interventions in ongoing project operations. It becomes apparent where priorities are adjusted, resources are reallocated and projects are restructured.

Adjusting priorities during ongoing operations

Strategic priorities are not static. Market changes, regulatory requirements or new business opportunities can lead to projects being assessed differently than originally planned. Cross-project management ensures that such changes do not merely exist on paper, but also have operational implications.

This may mean that a project of high strategic importance receives additional support, whilst other initiatives are deliberately slowed down. Prioritisation thus becomes a continuous process. A sound basis for this is provided by project prioritisation within the organisation, where initiatives are assessed and ranked according to clear criteria.

Priorities can thus be adjusted not only periodically, but also at short notice as required.

In addition to prioritisation, other operational levers are employed in day-to-day project management: capacities are balanced across projects to avoid overloads, scenarios are run through to better assess the impact of rescheduling, and defined escalation mechanisms are triggered in the event of conflicting objectives.

These interventions do not take place in isolation, but in conjunction with one another – and this is precisely where the real challenge of multi-project management lies.

Redistribute resources between projects in a targeted manner

In practice, resources are often the limiting factor. Skilled staff, budgets or external capacity cannot simply be multiplied at will. Cross-project resource management makes it possible to view these capacities within the overall context of the project and reallocate them in a targeted manner.

If a critical project requires additional expertise, a decision can be made to withdraw resources from less urgent projects. Such decisions affect several projects simultaneously and highlight the fact that resource management is a central element of multi-project management.

Starting, postponing or stopping projects

Portfolio-level management also involves making structural changes to the project landscape. New projects are not launched in isolation, but are assessed in the context of existing workloads. Similarly, ongoing projects may be postponed or deliberately terminated if they no longer align with current strategic objectives.

Steering committees as a key element

Regular steering meetings instead of isolated project decisions

Effective management requires established formats in which cross-project decisions are prepared and taken. Regular steering meetings do not involve discussing individual projects in detail, but rather addressing overarching issues: Where are bottlenecks arising? Which projects influence one another? Where are adjustments needed?

These bodies create a binding framework within which priorities, bottlenecks and conflicts are assessed in a structured manner.

In practice, however, it is evident that decisions often fail due to unclear responsibilities, despite such formats.

For steering committees to fulfil their role effectively, clearly defined responsibilities are required. Strategic prioritisation typically falls to portfolio managers, whilst resource managers decide on capacities and their allocation. Project managers, in turn, are responsible for the operational implementation of individual projects.

What is crucial here is not merely the existence of such a committee, but the binding nature of the decisions taken and their consistent implementation in day-to-day project work.

Clear roles between project management, the PMO and senior management

Project managers provide the operational perspective on their projects. The PMO consolidates information, standardises it for comparison and ensures a cross-project perspective. Senior management takes on the role of setting overarching priorities.

Effective management of multiple projects only works if these roles are clearly defined and decision-making processes are transparent.

Escalation processes for conflicting objectives between projects

Where several projects run in parallel, conflicting objectives are inevitable. Two projects may require the same specialists, budgets may not be sufficient for all planned projects, or deadlines may clash.

Clear escalation pathways ensure that such conflicts are not resolved informally or by chance, but are escalated in a structured manner to the appropriate decision-making level.

Control mechanisms within the system – how multi-project management is supported in practice

How multi-project management is supported operationally Multi-project management requires more than just organisational structures and regular coordination. It needs a robust, integrated data foundation and tools that highlight cross-project interdependencies. Only when information from scheduling, resource management and controlling is consistently consolidated can a sound basis for decision-making at portfolio level be established.

This includes, in particular, key performance indicators such as resource utilisation across all projects, schedule variances within the portfolio, the relationship between project priorities and available capacity, and bottleneck analyses of critical resources.

Only on this basis can well-founded decisions be made and the effects of adjustments realistically assessed.

Dependencies and schedule chains as a basis for project management

Delays in one project rarely fail to affect other projects. Effective project management therefore requires transparency regarding schedules and dependencies across multiple projects. In PLANTA Project, schedule structures are managed centrally and displayed in clear planning views such as Gantt charts. This makes it clear which milestones are interdependent and where schedule changes trigger knock-on effects.

For the management of multiple projects, this means that schedule changes are not assessed in isolation, but within the context of the entire project landscape. Decisions such as reprioritisation or schedule adjustments can thus be made on the basis of consistent and up-to-date data.

Resource and capacity management across multiple projects

In multi-project environments, resources are often the critical bottleneck. Whilst looking at individual projects in isolation reveals the requirements for each project, it does not show the actual utilisation across all projects. PLANTA Project provides a cross-project resource and capacity overview that highlights both overloaded and available capacity. For optimal resource planning in multi-project management, available resources must be coordinated across projects in such a way that deadlines and budgets are met throughout the entire portfolio.

In addition, skills matching helps to take into account not only available hours but also suitable qualifications. This makes management more concrete: if a project requires additional expertise, it is possible to check specifically which individuals with the necessary skills are available and where a redeployment would be appropriate. Resource management thus becomes a conscious, data-driven decision at portfolio level.

Aggregated key performance indicators instead of isolated status reports

Individual status updates provide important detailed information, but are of limited use for cross-project decision-making. Managing multiple projects requires aggregated key performance indicators that highlight trends across the entire project portfolio.

Traffic light ratings can serve as aggregated leading indicators to highlight critical trends across multiple projects.

PLANTA Project provides consolidated reports, trend analyses and dashboards for this purpose, covering aspects such as schedule variances, budget trends or resource utilisation across multiple projects. These metrics serve not only to provide information, but also as a basis for concrete management actions when structural bottlenecks or systematic deviations become apparent.

Up-to-date project data as the basis for timely decisions

Cross-project management is only as effective as the timeliness of its data. Delayed or manually consolidated information makes decision-making difficult, as the situation across the project portfolio has often already changed by the time measures can be implemented.

In PLANTA Project, project, resource and status data are centrally available on a shared project management platform and are continuously updated. This enables the PMO and management to make decisions based on consistent information. Measures such as prioritisation adjustments or resource reallocations can thus be implemented promptly, rather than having to compensate for the impact on other projects after the event.

In practice, multi-project management involves identifying interdependencies between projects and using these to inform decision-making. This is based on up-to-date, centrally available project data, which enables management across all projects.

Multi-project management in a challenging environment: balancing stability and dynamism

Project landscapes must be both stable and adaptable. Projects require a reliable framework, whilst priorities, resource availability and external influences are constantly changing. Governance therefore involves providing structures that enable both reliability and adaptability.

Why management must be reviewed regularly

Project initiatives are constantly evolving. New projects are added, existing ones are rescheduled, and dependencies change. Without regular review, previous assumptions remain in place even though the reality has already changed.

In practice, this means that priorities, resource allocations and schedules must be reassessed at fixed intervals. In PLANTA Project, such adjustments can be made based on current project and resource data, ensuring that decisions are not based on outdated planning information.

Dealing with short-term changes during ongoing operations

In addition to regular adjustments, short-term changes also occur. A key member of staff is absent, a project is delayed, or new regulatory requirements arise. Such events rarely affect just a single project.

A cross-project management approach ensures that these changes are assessed within the context of all projects. In PLANTA Project, the impact on other projects and resources can be made immediately visible. This reveals where bottlenecks are arising or which projects need to be adjusted.

A typical scenario illustrates the necessary level of intervention: a strategic project launched at short notice requires key resources that are already firmly allocated to ongoing projects. In such a situation, it is not enough merely to highlight the impacts – rather, conscious decisions must be made, such as delaying projects, reallocating resources or resetting priorities.

It is precisely this ability to actively reprioritise that distinguishes effective multi-project management from purely observational project management.

Conclusion: Multi-project management is the active management of the project portfolio

Cross-project management means not merely monitoring projects, but actively shaping the project landscape. It combines transparency with clear decision-making processes and concrete opportunities for intervention. Priorities are effectively implemented, resources are deployed thoughtfully, and conflicting objectives are resolved in a structured manner.

In day-to-day project work, this is particularly evident where priorities are actively adjusted, resources are consciously reallocated and interactions between projects are specifically managed – and thus precisely in those situations where decisions must be made under conditions of uncertainty.

An integrated database, such as that provided by PLANTA Project, lays the foundation for well-informed decisions at portfolio level – and for a project landscape that remains manageable even under dynamic conditions.

FAQ on multi-project management

What is multi-project management?

Multi-project management refers to the cross-project management of several projects whilst business operations continue. It ensures that priorities, resources and deadlines are coordinated within the overall context and actively adjusted where necessary.

Why is multi-project management important?

Because projects within a company do not run in isolation. Without management, conflicting objectives, resource bottlenecks and scheduling issues arise that affect several projects simultaneously.

What is the difference between this and multi-project management?

Multi-project management describes the organisational framework and methods for coordinating multiple projects. Multi-project control, on the other hand, involves specific interventions in ongoing projects, such as prioritisation or the reallocation of resources.

In everyday use, both terms are often used interchangeably, but they describe different levels: whilst multi-project management creates the structural conditions, multi-project control determines how projects are actually aligned and adapted during day-to-day operations.

It is only through this operational control that strategic goals are not only planned but also implemented under real-world conditions.

When does multi-project management become necessary?

When several projects are competing for resources at the same time, there are dependencies, or priorities need to be adjusted on a regular basis.

What challenges commonly arise in multi-project management?

Typically, it is not so much individual problems as their interplay: projects compete for the same resources, dependencies lead to knock-on effects in the event of delays, and short-term changes require rapid reprioritisation across the entire portfolio. The challenge lies in making these interactions transparent and making informed decisions in the face of uncertainty.
