Tam Tam Consulting has both. Technical expertise and a deep understanding of the contractual side. Especially their last mile discussions with the provider were key to sort out open technical and procurement aspects. By asking the right questions, they made sure we ended up with a solid, agile and cost-effective solution to keep our business moving forward.

For many years Tam Tam Consulting has assisted Adecco with the benchmarking and auditing of its mobile contract. Because the mobile market landscape is constantly evolving, we thought it was logical to explore the market and launch an official RFP. Tam Tam Consulting assisted Adecco in the entire process, from identification of the IT, HR and procurement requirements towards the preparation of the RFP document, negotiations and screening of the final contract. With this, Adecco realized a saving of 50% on its mobile contract, while the available mobile data for the employees was increased from 2GB to 5GB and high service levels were maintained.
