This document discusses the "big bang" and "phased" approaches to implementing a new Laboratory Information Management System (LIMS). The "big bang" approach involves a complete system implementation all at once, while the "phased" approach divides the implementation into multiple phases. Both approaches have advantages and disadvantages related to factors like time, resources, flexibility, and stakeholder satisfaction. The document recommends considering an organization's current situation, goals, processes, culture, and resources to determine the best implementation approach. Careful planning and stakeholder involvement are also keys to success.
