In order to turn your mobile project into a success, you should keep in mind that mobile projects are a little more complex than traditional IT projects. This is because a broad range of technologies are used in a typical mobile project and you need to have somebody in your team with know-how on all of them. This does not have to be (and most likely won't be) the same person, but you should be able to cover a broad range of technologies ranging from SAP back-end systems requiring ABAP and/or business process knowledge to mobile clients, for which some Java experience might be very beneficial. This post will offer some tips for how to successfully staff your project.
The image below gives you a first impression of the system landscape in a Mobile Infrastructure-based project; as you can see, for a mobile project you need know -how for client, middleware and back-end.
The information given is based on SAP xApp Mobile Time and Travel 2.0 and SAP xApp Mobile Asset Management 3.0. Most of it is valid for other Mobile Infrastructure-based applications as well.
Experience has shown that the following roles need to be covered by members of your project team:
Application consultant needs to have the relevant back-end knowledge for the specific solution that is supposed to be implemented in your project
Mobile consultant should know about Mobile Infrastructure configuration, mobile application installation and should be experienced in technical blueprinting
Technical consultant should have know how regarding Web Application Server installation and administration
Development consultant is required to know about enhancements to the mobile application front-end and/or about back-end enhancements
Project manager is needed like in any other project
So now that we have had a quick look at the different roles that you need to fill with your team members, let's see what the detailed skill set required to fill these roles looks like:
Mobile consultant
- Web Application Server
- Mobile Infrastructure
- General networking knowledge
- Security (e.g. SSL)
- RFC
- Job scheduling
- SAP role concept
Technical consultant
