OBSOLECENCE MANAGEMENT(OM)

• OBSOLESCENCE CAUSED BY CHANGE – INE9ITABLE AND CANT IGNORE

– ANTICIPATE ACCOMMODATE

OM IS PART OF LIFE CYCLE MANAGEMENT(PLCS) – MUST BE TAILORED TO SUIT THE NEEDS OF

PRODUCT AND PROGRAMME

–

SUMMARY (CONTD)

• PLANNED AND PHASED TECHNOLGY INSERTION

IS THE ECCONOMIC WAY TO MANAGEOBSOLESCENCE

•

NA9AL POLICY ON PLCS MAY NEED TO BEFORMULATED CONSIDERING OM

• COMPREHENSI9E LIFE CYCLE SUPPORT SHOULD
