Chapter 5 DOI: 10.4018/978-1-6684-9184-3.ch005 ABSTRACT This chapter evaluated the efectiveness of the current information communication technology systems in use by ELCIN and its impact on overall performance in the administration of the church. The study utilised a quantitative approach with a randomly selected sample . The fndings reveal that only 14% of ELCIN staf had PCs. On ICT skills competences, the digital illiteracy rates are high with databases (illiterate= 85%, literate=0%), PowerPoint (illiterate=87%, literate =13%), and Excel (illiterate=20%, literate=20%, not sure=60%). The study further reveals that there is generally non-usage (f=27, 90%) of specialised administrative software such as Oracle, Pastel, and SAP. The research also showed that there are varied reasons for the low adoption of ICT in ELCIN that include inadequate hardware and software and low skills capacitation among others. It is therefore recommended that ELCIN sends the staf members to refresher courses in basic ICT and to strengthen the digital literacy training. Also, proper system implementation should be accompanied by appropriate expertise.
