The Hayes-Wheelwright matrix is a four-stage model; each stage is characterized by the management strategy implemented to exploit the manufacturing potential. In stage 1, the production process is flexible and high cost, and becomes increasingly standardize, mechanized, and automated, resulting in an inflexible and cost-efficient process.
Cycle times can be modeled through manufacturing engineering if the individual operations are heavily automated, if the manual component is the prevalent one, methods used include: time and motion study, predetermined motion time systems and work sampling.
A criticism levelled against the Hay Guide Chart is that the choice of factors is skewed towards traditional management values: "The Hay system consistently values male-dominated management functions over non-management functions more likely to be performed by women.” [2]
[1] He became a professor at the Harvard Business School, eventually receiving the Philip Caldwell chair in business administration. [1] He worked with William J. Abernathy. [2] Professor Wickham Skinner was one of their mentors. [2] Hayes served as the president of the Production & Operations Management Society. [1]

The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently (as of 2024) in its 105th edition, published in 2024.
John Patrick Hayes is an Irish-American computer scientist and electrical engineer, the Claude E. Shannon Chair of Engineering Science at the University of Michigan. [1] He supervised over 35 doctoral students, coauthored seven books and over 340 peer-reviewed publications. [ 2 ]
[1] The similitude principle was developed by Wallace D. Hayes , a pioneer in hypersonic flow , which is considered to begin at about five times the speed of sound, or Mach 5, and is described in his classic book Hypersonic Flow Theory co-written with Ronald Probstein and first published in 1959.
