Comparable reporting in the case of structural changes - Part 2: Practical example of the use of comparable metrics in business planning and control

In the June edition of our magazine we outlined the essential requirements and principles for professional comparable reporting; in the second part of our report below, we demonstrate, by means of a practical example, how companies can set up a control system with comparable metrics in the case of structural changes. The focus here is on a pragmatic, system-based approach that meaningfully combines automation supplemented by manual input and deliberately restricts itself to a few selected planning and control-specific metrics.

Practical example - Baseline situation and vision

An industrial company, which operates internationally, is realigning its medium-sized organisation and supplementing its existing structure with product-oriented and segment-based logic. The aim is to map out clearer market and profit responsibilities and to align planning and control more closely with products and customers.

However, it should be possible for the management to analyse the new segments not only in the future, but also retrospectively over several years. Key questions concern the trends in revenues, results, and cash flow in the new segments. To this end, the historical data has to be selectively reconciled. 


Objective

For the company it is about having an additional planning and control perspective that provides historical comparability without changing the existing reporting logic. The original structure is retained as a reference while, at the same time, a new segment view is created.


System-based implementation

In the practical case that is being presented, the implementation of comparable reporting is supported by a system on the basis of CCH Tagetik, a financial platform that combines closing, planning and reporting - with expert AI that intelligently supports each process (a possible alternative would be, for example, Lucanet). The starting point is a structured comparison of the existing organisational units and the new product-oriented segments.

In the project, it was possible to derive a clear assignment to the new segments for a large proportion of the organisational units. In the system these assignments were defined on the basis of rules. On this basis, historical revenues, results, and cash flows can be automatically assigned to the new segment logic.

Important note

Automated derivations form the foundation of the entire approach. In the specific application scenario, this made it possible to transfer several years' worth of historical data into the new structure in a consistent format. The data is provided in a way that is reproducible and without the need for recurring manual interventions. This ensures that the new planning and control perspective remains viable in the long term and is not just a one-off analysis.

Supplementary classification and structured inputs

As in many comparable projects, the practical case study likewise demonstrates that not all situations can be automatically mapped clearly. It is moreover not always possible to assign, in particular, central functions, inter-divisional cost structures, or support units directly to a single segment.

In the specific project, a clearly defined supplementary process was set up, however, without using fully standardised allocation logic. Instead, the allocation took place directly in the system via digital input forms on the basis of existing profit centre structures and the professional assessments of the controllers. They were specifically involved and carried out some of the allocation manually on the basis of their detailed knowledge of business models and value chain inter-relationships. In this way, parts that could not be obviously assigned were able to be allocated comprehensibly and consistently to the new segments.

Please note

The aim was not to achieve complete theoretical perfection, but rather to create a solution that was both reliable and economically efficient.

Focus on the planning and control-specific metrics

A key principle of implementation in an industrial company is the clear focus on planning and control-specific KPIs. The emphasis is particularly on revenues, segment results and free cash flow.

Not every metric will be made comparable retroactively. This deliberate prioritisation ensures that the manual workload remains proportionate to the benefits. This increases the level of acceptance in the management.

Please note

The comparable reporting approach, described above, makes it clear that purely technical implementation is not required here, but rather that professional prioritisation by financial experts is always likewise required.

Integration of controlling and accounting

An adequate and effective comparable reporting approach does not end in the controlling department. In the practical case that was considered, the accounting department was also involved at an early stage because the new segments will have a direct impact on the financial reporting. 

In particular, consistent opening balance sheets have to be created for the new organisational structure. These serve as the basis for the ongoing accounting (cf. Fig.1). 

Fig. 1 Preparation of opening balance sheets as the basis for further analyses

Automated journal entries are based on ERP data with opening balance sheets in a new structure; at the same time, data consistency is ensured.

In the industrial company that is considered here, the implementation of this requirement was likewise supported by a system. The opening balance sheets were derived fully automatically from the legacy system data on the basis of a defined calculation logic and reconciled to the new segments. The underlying rules were defined once and then applied consistently. Subsequently, structured check reports were made available in order to identify any remaining inconsistencies and, if necessary, to make specific manual adjustments.

Interim conclusion

Using this approach meant that it was possible to ensure that the relevant balance sheet items have been fully and consistently assigned to the new segments while, at the same time, retaining the historical structure, which remains comprehensible.

Consolidated view and use in reporting

Following the transfer of the historical data, the values for the new segments were consolidated once again. This results in a coherent overall view of the company that includes both the previous structure as well as the new one.

The benefits of this solution are particularly evident in day-to-day reporting. The management can carry out evaluations both in the traditional organisational logic as well as in the new segment structure. Time series analyses over the course of several years will be possible and will provide comparable conclusions regarding the performance of the individual segments. Differences between the old and new structures can be traced at any time here. As both views are available simultaneously in the system it is possible for causes to be transparently analysed and explained. 

Another advantage is the ongoing usability of the solution. New periods can be shown in the new structure without any additional manual tasks. Even if further adjustments are made, the existing logic can still be used (cf. Fig.2).

Comparable reporting is generated in three steps for 1:1 and 1:n mappings, in each case with the maximum possible level of automation

Important note

Comparable reporting will thus become an integral part of business planning and control and not a one-off special evaluation.

Transparency and comprehensibility

It is of key importance that all assumptions, rules and supplementary inputs defined in the project are documented and versioned at the system level. This creates a high degree of transparency about the underlying derivations.

Please note

This is particularly important in the light of increasing requirements for comprehensibility and auditability. Regulatory frameworks, such as IFRS 18, are increasing the pressure on companies to clearly document and consistently apply the logic behind their planning and control systems.

Advantages realised in controlling and reporting

In the practical case study described above, the system-based solution plays a key role in meeting these requirements and, at the same time, enhancing reporting efficiency. The practical case study demonstrates that comparable reporting is not a theoretical concept, but rather that it can be implemented efficiently by using a clear methodological approach and appropriate system support.

The crucial factor is the interplay between professionally defined targets, intentional focus and technical implementation. 

Result

Companies that systematically reconcile historical data, prioritise relevant metrics and consider controlling and accounting to be integrated functions are able to create a robust foundation for their planning and control processes. With platforms such as CCH Tagetik or Lucanet it is possible to firmly and sustainably embed the aforementioned requirements in the system and to establish comparable reporting as an integral part of business planning and control over the course of many periods.
