Problem Analysis:
Current Pain Point/Root Cause that Affect maintenance
People
lack of competency
time consuming to travel, people need to attend the fault if cant remotely done
multiple preventive maintenance schedule/health check yearly
multiple vendor to managed (IPJOS, WPO, RFC must apply per vendor)
Coordination with regional team to attend site (CNZ, DDZ etc.)
lack of tracking on PM findings
manually tracking AR -open and close
Human error
Material
not enough spare
complicated spare management proses
Space and management to store spare
Machine/Equipment
old system
multiple NE, system, services
No info on fibre spare core availability (PMW work to rectify high loss)
NE offline issue currently monitored via system Zabbix. To enhance system to able separate issue due to equipment or GIT(router/switch). No info on IP switch and port router.
No E2E of TM network to be able to tackle issue faster
different series of vendors in TM network
OS version out of date
manual AR open and close
Method/Process
time cosuming
Different interface for different services
For Fiberhome DWDM & Huawei, CTAC manually adjust power
Complicated process and many level to go thru for approval
DWDM SDH manual reroute due to congestion
Currently verification of PM done by Tx.
Suggest verification of PM done by CNZ (exec/mgr) instead of Tx (NOC). If there’s issue/abnormal action then proceed to NOC.
Broadcast report PM compile manually (~ 1K report yearly)
Implementation not follow the SOP
Environment
weather - hujan
More new equipment's being installed without considering dimensioning of the current aircond system that may lead to system failure.
High Temperature in equiptment's room due to problematic air-conditioning system
TM Node
long and complicated proses to enter premises
Problem Definition:
Ineffective Maintenance
How the maintenance is currently done?
Manually or half manual
Same type of equipment but different schedule
When
is the problem occurred?
during health check / pm
Alarm Monitoring
Log trigger from syslog server
What
is the current problem?
pm takes too long
manual maintenance
difficulty to tackle issue faster
too many systems i.e. EMS/NMS
Why
do we need to improve the problem?
improve productivity
reduce human error
Better and faster troubleshooting
New Working environment and style.
reduce complexity of process/system
Where the problem occurred?
Equipment
People
across NOC that handle maintenance
Network
Who experience the problem?
NOC staff
Regional staff
