Oct2012 to May2013 Role: Sr. Java Developer Project # 2 – STAR NORTH Project Description:
- 6. When an operational move was completed for the Star North facility on February 4th , 2012, this moved the facility; however, systems from the Home Office (HO) to Logistics remained the same. After the operational move was completed the facility received limited access to Logistics Human Resource (HR) applications, reports and systems. Subsequently, several unique manual processes were put in place to accommodate accordingly. The intent of the Star North project is to officially complete the transformation from a Home Office Facility to a Logistics Facility. This project will implement Logistics Human Resource systems, applications and reports in the facility enabling Star North Facility to shift away from numerous manual processes which are used to enforce Logistics processes, procedures and standards. Star North, Facility #8677, and Logistics Human Resource applications must interchange existing production systems, established reports and migrate current associates from Information Systems Division (ISD) Division Five to Logistics Division Thirteen. This will be achieved by an install, interchange and data transfer from Home Office systems and applications to Logistics Human Resource systems, applications and reports. Although a majority of the manual processes will be remedied, a few manual processes will still remain which were deemed Out of Scope such as the Human Resources Tracker used to manage Leave of Absence (LOA), Associate of the Month (AOM), Accommodations, and Management Contacts. Due to cost benefit associated with the HR Tracker, the said application will not be installed. Roles and Responsibilities:
