The second is related to where employees still need to improve their ability to maintain facilities in order to provide comfort to service users and are often late so that services are hampered. The third is related to responsiveness where employees are still lacking in providing innovative services so that they are still unable to compete with other parties but in responding to complaints and community needs are sufficient.
