Our small digital agency is currently running into project management problems, as we're following the waterfall methodology which we continuously have hold-ups in the design phase. Our clients are initially very active with feedback in the beginning but then it becomes 2-5 days sometimes before we get feedback on a design, which is affecting our pipeline as well as milestone payment cash flow. Can anyone recommend a web design pm course that will help us fix our problems? We may need to learn a new methodology i.e. agile, scrum etc in-order to fix the problem. We build websites on Magento, Shopify and WordPress. Any advice would be greatly appreciated!
Although project management training is great and I would recommend Agile or Scrum methodologies to assist you with your challenges, it sounds like the issues you are having may be related to needing some definition around roles and responsibilities, setting expectations and communication of the impacts of a slow response time. Using different methodologies can definitely help with that but in the near term maybe you just need some coaching in the softer skills to get through your immediate challenges.
I am a project management coach and would be more than happy to give you some pointers to help you out.
