Five whys (or 5 whys) is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. [1] The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "why?" five times, each time directing the current "why" to the answer of the ...
The development and improvement of products and technologies in accordance with TRIZ are guided by the laws of technical systems evolution. [1] [2] Its development, by Soviet inventor and science-fiction author Genrich Altshuller and his colleagues, began in 1946. In English, TRIZ is typically rendered as the theory of inventive problem solving ...
Although it may seem simplistic, the 5 Whys can be an invaluable tool for uncovering hidden problems and generating new ideas. Pugh matrix; Morphological analysis; 6 thinking hats; The method of loci: The method of loci is a strategy for memorizing new information. It is a mnemonic device that involves the visualization of placing pieces of ...
The iteration of such strategies over the course of solving a problem is the "problem-solving cycle". [ 30 ] Common steps in this cycle include recognizing the problem, defining it, developing a strategy to fix it, organizing knowledge and resources available, monitoring progress, and evaluating the effectiveness of the solution.
D2: Describe the Problem: Specify the problem by identifying in quantifiable terms the who, what, where, when, why, how, and how many (5W2H) for the problem. D3: Develop Interim Containment Plan: Define and implement containment actions to isolate the problem from any customer. D4: Determine and Verify Root Causes and Escape Points: Identify ...
Systematic inventive thinking (SIT) is a thinking method developed in Israel in the mid-1990s.Derived from Genrich Altshuller's TRIZ engineering discipline, SIT is a practical approach to creativity, innovation and problem solving, which has become a well known methodology for innovation.
In empirical studies of three-dimensional problem solving, Bryan Lawson found architects employed solution-focused cognitive strategies, distinct from the problem-focused strategies of scientists. [20] Nigel Cross suggests that "Designers tend to use solution conjectures as the means of developing their understanding of the problem". [21]
Gigerenzer & Gaissmaier (2011) state that sub-sets of strategy include heuristics, regression analysis, and Bayesian inference. [14]A heuristic is a strategy that ignores part of the information, with the goal of making decisions more quickly, frugally, and/or accurately than more complex methods (Gigerenzer and Gaissmaier [2011], p. 454; see also Todd et al. [2012], p. 7).
