Jonesa*  \na Bioengineering Branch, Mail Stop N239-8, NASA Ames Research Center, Moffett Field, CA, 94035-0001, [harry.jones@nasa.gov](harry.jones@nasa.gov)  \n* Corresponding Author  \nAbstract  \nMany engineering methods have been developed to help management select technology for a system design or further research. The simplest way to compare technologies is to use a checklist containing all the more or less important selection criteria, so that nothing is overlooked. The criteria usually include cost, safety, reliability and maintainability, and potential problems such as noise generation and microgravity sensitivity. The next step typically is to weight and score all the criteria. The process of weighting and scoring is helpful in bringing out different priorities and reaching a shared point of view. Group technology selection methods are designed to highlight initial disagreements and produce a shared consensus. Often a frank discussion led by management rather than decision analysts can be more effective. The final selection depends on management and engineering judgment and may include programmatic and organizational factors that are beyond the engineering checklist. The objective of engineering technology selection methods is to provide engineering information to assist management in making sound decisions.  \nProject management and technology selection are assumed to use rational engineering analytic methods, but they often do not. The reason is that human insight, intuition, and “gut feel,” rather than logic, more frequently determine our decisions. Project selection and management are strongly influenced by nonrational psychological influences, which can produce unjustified confidence and determination.  \nNevertheless, there is a strong need for space projects to do rational project analysis and selection. Demonstrating a rational spirit is necessary for a scientific and technical organization. Professional ethics at its best requires an open, honest, and fair process, without damaging politics. Rational analysis can help improve good projects and avoid selecting bad ones. A sanity check using rational analysis guided by a checklist can help avoid egregious and damaging errors.  \nKeywords: (project selection, checklists, engineering judgment, intuition, gut feel, nonrational decisions)  \nAcronyms  \nESM = Equivalent System Mass LCC = Life Cycle Cost  \nNPD = New Product Development NPV = Net Present Value Pr(LOC) = Probability of Loss of Crew R&D = Research and Development TRL = Technology Readiness Level WYSIATI = What You See Is All There Is  \n1. Introduction  \nSpace projects are usually supported and approved based on management judgment and the organizational budget process. The project selection process should also include an engineering technology selection method, such as using a checklist of criteria. This can help prevent the approval of seriously flawed project.  \n2. Engineering methods to select technology  \nThis section describes technology selection using checklists and mentions some other analytic and quantitative methods. A radar chart can be used to display the criteria on the checklist.  \n2.1 Checklists  \nChecklists are a simple way to identify the relevant factors in making a technology selection decision. Neglecting an important systems engineering consideration such as risk can be very harmful.  \n2.2 Space project selection criteria  \nA new space technology should not be selected for flight unless it meets the well-known criteria of safety, availability, performance, and cost. Safety appears to be most important in selection, availability next, then performance, and cost appears least important. But any single criterion can be the deciding factor. A candidate technology can be rejected because of deficiencies in safety, availability, performance, or cost.
