Hello,
I've been very frequently involved in procurement of electronics components like programmable Logic Controllers (PLC), process instruments and electrical equipment. We follow a well-defined procurement process/procedure for purchasing different components. I'll define for you the complete list of activities involved in the procurement process and all major milestones. I'll provide you representative durations for certain range of tasks. They are basically dependent on the size of procurement being initiated. Furthermore, all responsibilities will be clearly defined for each activity.
The procurement process is almost sequential in nature and you can add up individual durations to come up with total time of the process. I'll provide you a Gantt chart of the whole process to be developed in Microsoft Project.
I'll briefly describe each task/activity to provide you a crystal-clear procurement plan.
Hoping for a positive response,
Regards,
