In 2009, it was determined that a hands-on RCA model would be an effective way to demonstrate how RCA works. The ROSA application answers this need, and was designed as an interactive tool to aid in better understanding the principles and costing approach of resource consumption accounting. ROSA should be viewed as a cost planning and analysis tool and not as a pricing/profitability application. The ROSA open-source package contains:
ROSA manual – To start the install process, double-click Autorun in the ROSA_USB compressed zip folder.
Note: The Palo BI Suite support material should be used in conjunction with the ROSA Manual where necessary, particularly in areas concerning Palo installation, set-up and operation.
Features
ROSA uses the business intelligence application called Palo. Palo allows the ROSA base model database to be pre-configured so that the user can explore the look and feel of how a RCA model functions. Some of the primary features of the RCA open-source application are:
RCA modeling
*cost objects in an RCA model
*planning a cost object's output and primary costs
*importing of master data and planning data values
Limitations
There are certain cost modeling limitations inherent in the ROSA application. These limitations are specific to Version 1.0 of the ROSA application and should not be viewed as static. In other cases, customized versions of ROSA have been developed to fulfill client-specific requests addressing their firm's individual costing requirements.
No ‘actual’ costs – ROSA is a stand-alone application and does not have integrated links to import data. It supports the construction of an RCA model for cost planning and analysis. ROSA does not currently support the comparison of actual to plan within the application. The planning aspect allows for the definition of consumption relationships with operational resource quantities, valuing the resource quantities with dollars, and calculating product and service costs.
Excess/idle capacity – There is a limited ability to isolate excess/idle capacity in the application. The application currently deals only with planned information and is therefore not able to provide information on actual excess/idle capacity.
Model size limitation – The ROSA model was designed for optimum use for businesses with limited size RCA applications. However, the underlying database and technology used in this model is extremely scalable.
No profitability reporting – Rosa Version 1.0 is solely for the purposes of cost modeling. Customer or product revenue cannot be accommodated in this Version 1.0 of the application and reports on customer or product profitability are not provided.
This application uses an open-source Business intelligence software engine called Palo, published by . Palo has been designed as an Add-in to spreadsheet software.
