  2. Quality Management Maturity Grid - Wikipedia

    en.wikipedia.org/wiki/Quality_Management...

    The Quality Management Maturity Grid (QMMG) is an organizational maturity matrix conceived by Philip B. Crosby first published in his book Quality is Free in 1979. [1] [2] The QMMG is used by a business or organization as a benchmark of how mature their processes are, and how well they are embedded in their culture, with respect to service or product quality management.

  3. Thin lens - Wikipedia

    en.wikipedia.org/wiki/Thin_lens

    A lens may be considered a thin lens if its thickness is much less than the radii of curvature of its surfaces (d ≪ | R 1 | and d ≪ | R 2 |).. In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces.

  4. Humphrey visual field analyser - Wikipedia

    en.wikipedia.org/wiki/Humphrey_Visual_Field_Analyser

    The analyser will provide a lens strength and type (either spherical and/or cylindrical), if required for the test. In these instances, wire-rimmed trial lenses are generally used, with the cylindrical lens placed closest to the patient so the axis is easily read. The clinician can alter the fixation targets as per necessary (see Fixation ...

  5. Hayes-Wheelwright matrix - Wikipedia

    en.wikipedia.org/wiki/Hayes-Wheelwright_matrix

    The Hayes-Wheelwright Matrix, also known as the product-process matrix, is a tool to analyze the fit between a chosen product positioning and manufacturing process. The first dimension of the matrix, the product lifecycle, is a measure of the maturity of the product or market. It ranges from highly customized products with low volumes, to ...

  6. Implementation maturity model assessment - Wikipedia

    en.wikipedia.org/wiki/Implementation_maturity...

    Implementation maturity matrix, which is an adjusted version of the test maturity matrix found in the test process improvement (TPI) model developed by Sogeti. The IMM matrix allows an organization to gain insight into the current situation of its implementation processes, and how it should pursue the desirable situation (i.e. a higher maturity ...

  7. Ray transfer matrix analysis - Wikipedia

    en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

    Note that, since the multiplication of matrices is non-commutative, this is not the same RTM as that for a lens followed by free space: = [] [] = []. Thus the matrices must be ordered appropriately, with the last matrix premultiplying the second last, and so on until the first matrix is premultiplied by the second.

  8. Electron optics - Wikipedia

    en.wikipedia.org/wiki/Electron_optics

    Magnetic lens. Electron optics is a mathematical framework for the calculation of electron trajectories in the presence of electromagnetic fields.The term optics is used because magnetic and electrostatic lenses act upon a charged particle beam similarly to optical lenses upon a light beam.

  9. Maturity model - Wikipedia

    en.wikipedia.org/wiki/Maturity_model

    A maturity model is a framework for measuring an organization's maturity, or that of a business function within an organization, [1] with maturity being defined as a measurement of the ability of an organization for continuous improvement in a particular discipline (as defined in O-ISM3 [dubious – discuss]).
