Speed up and automate your decisions!

Decision Engine is a segment and product-independent solution that can handle various business-related decisions in a centralised platform, even the complex ones. You can easily add and update business-specific logic for any decisions. This allows you to react rapidly to the challenges of the turbulent banking environment with minimum risk and cost while your sensitive knowledge stays in-house.

Product Details

If you are looking for a segment and product-independent Decision Engine solution that can handle various business-related decisions in a centralised platform, even the complex ones, you are at the right place! Our solution is enhanced by user-friendly features designed to speed up maintenance and automate any business decisions in any banking processes, like pre-screening, scoring, monitoring, collection and so on. Business rules and decision logic with graphical visualisation can be built and customised by the Bank’s employees with relevant roles, even without deep IT knowledge.

The engine can work for pre-screening, classical scoring and any additional decision points. It is capable to handle an unlimited number of different or similar decision logics, which can differ by customer segment (including sub-segments), product, product variant, etc. The models can be different by product or client sub-segments. They can be versioned and test-live models can be compared (champion-challenger). All parameters within the system are base parameters therefore mass upload of data components are feasible through excel files.

The built-in decision tree enables users to analyze results and gain more knowledge on approvals or rejections. The system can work as stand-alone Decision Engine as well as it can be integrated with ApPello Loan Origination and Debt Collection Systems or other solutions. Furthermore, the decision engine is able to provide alternative loan offer combinations. Besides loan origination, ApPello Decision Engine can be fund of monitoring and collection strategy-development.

data processing

The strength of the Application lies in its openness and flexibility. The Solution is capable of taking the input data necessary for the rating and scoring process from any existing systems of the bank and also from external data sources, while the final output generated as a result of the rating or scoring workflow can be used by any connected application.

For example: the data from the loan origination solution or individual parameter tables are evaluated, scored, aggregated and assessed by ApPello Decision Engine. XMLs arriving from the Loan Origination solution are managed by the Engine and the processed data is sent back by the same manner. Having regard to the frequent regulatory and environmental changes, in case of the expansion of the XML the system is able to handle the assigning new tags to the new variables with the help of configurable interface.

As a result of the evaluation of the application, the Enginiers are able to provide clear answers and information of further workflow steps (acceptance, rejection, manual review,mitigation strategy: surcharge, guarantor, cover) for the Loan Origination System thus reducing operational risk and improving efficiency.

scorecard definition

The Decision Engine is responsible for scorecards and for their maintenance. Questionnaires and scorecards can be flexibly and periodically adjusted to reflect regulatory requirements or credit policy changes. Within the process, users are able to parameterise all rules in parallel.

Scorecards can be defined for different client segments, for different loan products and also for different purposes, such as pre-scoring and client scoring. Existing scorecards can be copied and modified into different versions.

Challenge your
calculation models

ApPello Decision Engine is a powerful tool to challenge your practices and build up different models that can be versioned and test-live models can be compared.

To make testing easy, there is a possibility to mass import test data from an XML data structure. XSD schema is available to download to be able to generate the XML data structure. Test data can be run through calculation trees to verify the correctness of it or to fine tune it. Based on the mass test data import functionality portfolio based testing and champion challenger modelling are supported as well.


The Decision Engine contains parameterized data models, processes and rules so for a new product or a client sub-segment further questionnaire and scoring models can be created by the Bank’s experts. When it comes to modification of a logic or parameter board, it is possible to add new parameters, clone, inactivate/activate or archive the old one without vendor or IT intervention thanks to the easy-to-use system.

It has never been so easy to orchestrate, test, evaluate the scorecard’s rules with the help of decision tree that visualizes the whole decision process. The system’s calculation/evaluation logic is highly formable and able to manage several logics at the same time based on the versioning function. For example, in a campaign for the same product different interest rates or conditions are applied.


Did you know that adding more additional input fields on a Loan application form you loose measurable number of new clients?

Our Decision Engine is integrated with a leading Workflow engine (Camunda) and with our Customer Portal. This 3 tools together makes a very flexible solution for digital decision making. For example users can design and even test new flows within hours. Input templates can be managed dynamically based on the previous behaviour of recently aquired clients.

For ALL segments &
complexity levels

The Decision engine serves both retail and non-retail segments. The risk conditions can be separated from each other, be associated with the given segment and work independently.

The Engine supports complex calculations for non-retail and retail segment using the advanced statistical and mathematical functions of the system. Logit transformation or PD calibration can be quickly implemented by the risk experts of the bank. The system also manages the different steps of the PD rating calculation (model PD, overruled PD, decided PD, etc.) and expected loss of calculations.
