In spite of enormous investment and remarkable advancement in information system technology (IST) corporations, human integration remains the dominant factor in their success. While 10% of the failure can be attributed to technique failures, 90% are due to human issues. The purpose of this qualitative phenomenological study was to capture the lived experiences of 25 employees in their different midsize corporations in southern California. Moustakas' modified van Kaam methodology assisted in the analysis of data collection in the study. The data and analysis indicated the following themes necessitating organizational success during IS rapid change and implementation: (a) healthy working environment,(b) effective communication, (c) alleviate resistance to change, (d) assimilation, (e) minimizing stress, (f) knowledge sharing, (g) effective leadership, (h) empowerment, (i) risks taking, and (j) means of communications and collaborations. Several of the emergent themes corresponded with research on leadership, organizational and system theories perceived such as (a) strategic planning, (b) training and honing skills, and (c) motivating innovation.
