“…We observe four interrelated research streams in the emerging literature on technical debt: (a) taxonomy, frameworks, and perspectives on technical debt [1,2,3,4,5,6,7,8,9]; (b) identifying, measuring, and visualizing technical debt [9,10,11,12,13,14]; (c) measuring and assessing the impact of technical debt on project and firm performance [6,15,16,17,18,19,20,21,22,23]; and (d) decision frameworks for managing technical debt [3,24,25,26,27,28,29]. Moving beyond the metaphorical conceptualization of technical debt, these four streams of research collectively pave a way to develop rigorous empirical models that could be used to derive appropriate policies for managing technical debt.…”
