I worked with Tim as his team leader for almost 3 years. 
Tim has excelent process and SAP knowledge in combination with the strong ability to structure, analyse and timely deliver solutions for challenging and complex business and technical requirements. His effectiveness in leading meetings and workshops cross teams and/or business with his positive and delivery orientated attitude was outstanding. He became officially a technical lead / architect for SD area in the project. 
Tim is a hard working, very professional consultant highly focused on effectiveness and customer relations.

During his engagement Mr. Radlak has provided professional support in the area of functional design, maintenance and 3rd level support for SAP ERP MM, SD, LE areas. Mr. Radlak proved to be a very experienced functional consultant who is able to communicate and cooperate with BMW employees and Lodestone colleagues in a very professional and friendly way. Deliverables provided by Mr. Radlak were always provided in-quality, in-budget and in-time even for short notice requests of BWM.

We hereby confirm that Timothy Radlak, during almost five-year partnership with SAP Training Center Poland  repeatedly conducted numerous open trainings and dedicated workshops covering execution and configuration of logistics processes in SAP ERP (MM / SD / LE / WM)
Timothy proved high level of both technical competence and interpersonal skills reaching average ratings of 6.8 (on a scale to 7.0). He managed to establish a good connection with groups of participants, not only passing a professional knowledge but also a great passion.

Tymoteusz has constantly delivered very high quality work to the project (above expectations). He contributed to a training success in a difficult and new area of SRM module. His soft skills were very much appreciated by the training attendees. It would be a pleasure to have Tymoteusz again in a team in the future.

Tymek prowadził szkolenia dla konsultantów z zakresu MM, w których brałem udział. Oprócz bardzo dobrych zdolności do przekazywania wiedzy, które wykazał, na uwagę zasługuje również jego dogłębna znajomość modułu MM, a także doświadczenie w realizacji projektów do którego nawiązuje. Polecam.
