I have always earned the trust of team members and stakeholders alike by being true to my word. Specifically, there was a circumstance when a stakeholder had been promised, that a particular portion of a project would be complete by a certain date and the time. Unfortunately, this time frame was not met. I did an extensive evaluation on the reason for the failure and demonstrated via reports, charts and graphs a more realistic and feasible time frame. In adhering to this time frame, this particular portion of the project was completed as forecasted. Going forward, as a key contact for this customer, I had their complete trust. When the time came to negotiate the next phase of the project, they requested me and my team. They trusted that I would be fair, upfront and honest in my estimations.
I have great technical writing skills. In my past position as a business analyst I had created end-to-end process documentations for numerous complex business processes. I had analyzed and evaluated the the business activity from end-to-end. I identified and documented the entry criteria, stakeholders, the inputs, the outputs, the related activities, and performance measurement criteria along with a end-to-end process flow. In addition, I have also recently created internal control procedures that are currently being reviewed by the business process owner and senior management to be published as department-wide policies and procedures.
