• WGBH is the flagship station in the PBS system producing more than one third of the content distributed nationally.
IntroductionIntroduction
BackgroundBackground
• Over the years technological advancements moved the facility infrastructure from analog to digital but the production workflow was essentially the same .
• Workflow was mainly tape based with file based islands.
• This was a linear process involving movement of physical media from one step to the next toward the final deliverable

Why Fix It If It Isn’t Broken?Why Fix It If It Isn’t Broken?
• We live in a multi-channel multi-distribution platform world.
• We are doing more with less.
• Moving around physical media is inefficient
• CPU power, storage capacity and network bandwidth are increasing at an exponential rate. (Moore’s Law). Cost is coming down.
The GoalsThe Goals
• Ingest once output to all platforms
• Centralize ingest and trans-code services
• Desktop browsing and logging of SAN content
• Content remains as a file through process
• Archival for finished programs and raw footage

• In Fall 2008 WGBH Production Services (PS) began planning
• PS and Boston Media Productions (BMP) collaborated on workflow definition.
• BMP was already moving toward a file based workflow
• BMP needed more storage and a streamlined production process
• PS needed to sign up the first client.
PlanningPlanning
The ProcessThe Process
• Define workflow and deliverables with key stakeholders
• Establish a list of users and their access permissions
• Map out the folder structure of the storage volume and allocate space
• Develop operational procedures
• Educational seminars and training of users and support staff
