The phrase "a three phase process" is correct and usable in written English.
You can use it when describing a procedure or method that consists of three distinct stages or steps.
Example: "The project will be completed in a three phase process, starting with research, followed by development, and concluding with testing."
Alternatives: "a three-step process" or "a tri-phase process".
The few publications[ 4, 52, 53] are based on a three phase process: development, implementation and evaluation, as proposed by Goldenhar and colleagues[ 43].
These functions along with ABC transporters have been implicated in a three phase process of protecting nematode intestinal cells against environmental toxins (Cotton et al., 2014), and direct evidence for existence for six of these proteins has been established in the intestine of A. suum, of which four were inferred to be positioned on the integral intestinal membrane (Rosa et al., 2015).
The methodology consists of a two phase process.
The CRRP approach is in essence a two phase process.
With detailed understanding of the current development process (refer Fig. 3), it was mapped with a five phase process.
Under a two phase process, the stadium's capacity will be increased from 21,566 to 30,000 by 1 May 2015 for $65 million, and a canopy roof covering most permanent seating areas added by 1 May 2016 for $40 million.
Relevant articles were selected using a two phase process.
Seventeen reviewers extracted the data independently in the first of a two phase process.
As noted previously, Burton et al. [ 62] suggested that (1,3 1,4 -β-glucans might be assembled in a two phase process that involves more than one enzyme, and it was proposed that either XETs or GT48 callose synthases might be involved.
Quick et al. proposed a seven phased process model, upon which they conducted analysis to client-side artifacts for three cloud storage products to determine whether files were inadvertently modified during collection from these cloud storage services.
A dynamic model, called "immunoediting", more appropriately emphasizes the dual roles of immunity and describes tumour and immune system interactions in a chronological three phase process: elimination (immunosurveillance), dynamic equilibrium and escape [ 60, 61].
