Issue
A decision is required on the technical approach to provide a new UI for PPM Item creation & maintenance:
- develop a custom app in-house
- purchase a partner solution
- modify standard UI using SAP Screen Personas
Recommendation
It is recommended that a custom app is built in-house, due to the following factors:
- Better user acceptance
- Alignment with Syway development approach for complex build
- Full influence over design to meet business requirements
Background & Context
The 'Portfolio Items' app is the main transaction used for executing PPM processes in S4HANA. The standard UI for this app comes with the following shortcomings:
- Based on old WebDynpro technology; the screens are not user friendly - they are convoluted, poorly laid out and not aligned with Fiori design concepts.
- Creation of a PPM Item requires multiple steps, navigating back and forth between S4HANA and SAC Planning. The standard UI cannot guide the user through this process and gives no indication of completeness of the required data.
- Business expectations for the user interface are based on the current WeGo/Accolade and Colmar tools which provide more user-friendly and intuitive user interface than PPM. KDD096 - replacement of Accolade assumes that a new improved UI will be provided
SAP does not have any improvement for the UI planned on their roadmap and have suggested a partner solution from sophisTex which provides a more flexible, intuitive and user-friendly interface. The following features are included:
- S/4HANA certified Add-on by SAP ICC
- Achieves Clean Core, no impact on S/4HANA EPPM upgradability
- Delivered with a default set of configuration to reduce implementation time
- Flexibility to further customize and enhance
- Stage Gate approval functionality is incorporated.
SAP Screen Personas provides capability to reformat and simplify WebDynpro screens.
The alternative is to develop a custom app in-house which, in conjunction with the SAP Consulting Solution for Stage Gate approvals, would provide the same capabilities.
Assumptions
It is assumed that:
- All options will require internal custom development for:
- Integration with OpenText
- Integration with SAC
- Automation of follow-on actions on Stage Gate approval
- The sophisTex solution will be fully tested and relatively bug-free, while an in-house development will inherently require more effort in testing and resolution of bugs.
- A dedicated UI developer would be required for a fully custom UI build.
- There will be approximately 2000 users of PPM
- SAP PPM licenses will be required regardless of the UI
Constraints
N/a
Impacts
The decision on UI does impact up-stream or down-stream processes or data.
The main impacts of the decision are:
- Financial (both to the project and ongoing BAU costs)
- In-house development team capacity
- Time to deliver
- Testing effort
Financial Impact
- The recommended option to develop an in-house solution has a lower cost, better user acceptance both for the project and ongoing.
- The sophisTex solution has a subscription-based pricing model with ongoing costs based on user numbers.
- Screen Personas has similar cost as the custom UI development but may have limited flexibility on UI
- Standard app is not a feasible option as it challenges the decision of KDD096
