    Sr. Project Planning, Scheduling and Data Analyst

    United States - Tests: 7 - Portfolio: 3

    Hello! Do you have a project you NEED to keep on schedule and deliver on time? For every milestone you miss you are in danger of missing your delivery date. Schedule slips mean you reduce your profit and your customer loses confidence you can deliver when you said you would. What you need is a project plan and schedule that will help you keep track of your project. Your schedule needs start of project, durations for each task, and a good logical network of predecessors and successors. Once you have that you need to baseline your project so at the end you can analyze where the bottleneck might have occurred. Let me help you build a realistic schedule so you can meet delivery on schedule which will help you deliver on budget. I have helped major aerospace companies achieve their goals on delivery saving them lots of $$$. I've also started helping out small companies so they can grow and profit as they implement better planning for their projects and products. Remember, you need to keep track of your projects and your production/services to optimize your business. You need my help whether your business is virtual or you have a physical location. Let me know if you have any questions. Regards, Minerva
