By performing a comprehensive system analysis and assessment, businesses can ensure that their system is suitably configured and ready for integration with a three-way financial model.

Conceptualization & Design

Integrating a three-way financial model into an existing system requires careful conceptualization and design. There are several steps involved in this process, including assessing financial model requirements, designing the financial model, and creating documentation. Below is an overview of these steps.

Assessing Financial Model Requirements

The first step in integrating a three-way financial model into an existing system is to assess the financial model requirements. This involves determining the needs of the organization, identifying the data that needs to be included in the model, and specifying the desired outcomes and outputs. This is an important step as it helps ensure that the right data is included in the financial model and that the outputs of the model meet the needs of the organization.

Designing the Financial Model

Once the financial model requirements have been assessed, the next step is to design the financial model. This involves creating a framework for the model, establishing the accounting rules that will be used, defining the assumptions and parameters, and testing the model to ensure accuracy and reliability. It is important to ensure that the model is designed in a way that is both comprehensive and efficient.

Creating Documentation

Once the financial model has been designed, the next step is to create documentation. This includes creating user manuals, tutorials, and training materials to ensure that users can easily understand and use the model. It is important to ensure that the documentation is comprehensive and well-written so that users can understand how to use the model and get the most out of it.

Integrating a three-way financial model into an existing system requires careful planning and execution. The steps outlined above can help ensure that the process is successful and the model can meet the needs of the organization.


The implementation process of integrating a three-way financial model into an existing system involves building necessary components and connectors, ensuring data integrity, and ensuring data security. This section provides an overview of each step.
