Our Improvement Goals
Planning process is a
nightmare – takes too
long, complicated,
requires too many
discussions in large
forums…
Estimated delivery date
of the backlog is
unknown.
Major epics don’t have
breakdown and
estimation for the GA
delivery. Big picture is not
clear
It takes too much
time to stabilize the
Sprint (monthly)
release
Stability of the main
truck is not consistent
“Feature team” is not a
silo - not fully allocated
for the feature
“Feature team” is not
permanent and in many
cases changes every
month.

Path to Tuscaloosa
Key Callouts:
• Now that we are on track to have BDN’s up and running in Seattle and Freedom, we need to focus our efforts on our approach to market trials
• Plan is to deploy one (or more) test CMs in the HE (off the vCMTS + RPS setup) with a banana pi and test server behind it to generate traffic and tests
Key Upcoming Milestones and Activities:
• Finalized physical architecture and BOM for deployment Tuscaloosa on 3/31
• Determine how CableOS code will be upgraded in the BDN and during market trials; can code be pushed directly to the HE? Who does the code upgrade?
• Next Code Drop: PI-3 iteration 1 on 12/2
