For the second time this year, all project owners of the six difference VIA Water projects in Mali were invited to join the VIA Water café on the 21st of December. After getting to know each other and the projects better during the first meeting (September 2017) it was now time to dive into more detail into the projects. We started with an exchange on how the Sharing Skills seminar contributed to the daily working life of the project owners. What was most appriciated were the different personality types and how they can respond to each other, and which ways of communication work best when working in a team with different types of people. After this we had a group discussion on the main challenges related to Management, HR, Marketing, Communication and Finance. Per group people noted their main three challanges and after that we discussed them one by one. The most important challanges were related to the sustainability aspect of the project after the funding, how to make sure users will use their new application, webiste of platform, how to make the project well known to a broad public and how to deal with 'partners' who don't want to cooperate. Due to lack of time we couldn't do the second activity planned for the day, but we have decided to discuss to topic of sustainability during the next VIA Water café that will probably be held during the visit of Titia mid februari.
