Laboratory systems have grown complex over 20 years. Adding features can harm functionality, meaning more options don't always equal better performance in daily lab operations.

Area of Science:

  • Laboratory automation and informatics
  • Clinical laboratory science

Background:

  • Laboratory information systems (LIS) have significantly evolved over the last two decades.
  • Increased system complexity due to feature additions may negatively impact overall functionality.

Purpose of the Study:

  • To highlight the discrepancy between the number of features and actual day-to-day operational functionality in laboratory systems.
  • To inform procurement processes regarding the true measure of system utility.

Main Methods:

  • Qualitative analysis of system evolution trends.
  • Review of common practices in laboratory system procurement and feature evaluation.

Main Results:

  • A growing awareness that feature count on a request for proposal (RFP) is not a reliable indicator of practical functionality.

  • Observed instances where extensive feature sets have led to decreased usability and operational efficiency.

    • Conclusions:

    • Procurement strategies for laboratory systems should prioritize demonstrated functionality over sheer feature quantity.
    • A critical evaluation of how added features impact workflow and user experience is essential for effective laboratory system implementation.
