      Learning opportunities exist but management issues persist

      Lead engineer
      Recommend
      CEO approval
      Business Outlook

      Pros

      Good learning opportunities and strong domain knowledge in the organization. The merger with the parent organization can help improve processes and collaboration across teams.

      Cons

      There are still many integration and management issues in the Med2 team. In many cases, decisions are influenced by a small group of people, which reduces wider technical participation and open discussion. Management approach is not consistent across teams. Sometimes personal relationships seem to have more influence than technical contribution or delivery performance. This affects team morale and limits independent ownership.
