Note(s): Internal Determinants is an aggregate variable made up of five management commitment-related lean practices (H1MC1, H1MC2, H1MC3, H1MC4, H1MC5), five teamwork-related lean practices (H2TW1, H2TW2, H2TW3, H2TW4, H2TW5) and four adaptabilities to change related lean practices (H3AC1, H3AC2, H3AC3, H3AC4). The external determinant is an aggregate variable made up of five community incorporation-related lean practices (H4CO1, H4CO2, H4CO3, H4CO4, H4CO5), five government support-related lean practices (H5GV1, H5GV2, H5GV3, H5GV4, H5GV5) and four other philanthropic organisations related lean practices (H6OP1, H6OP2, H6OP3, H6OP4)
