∗ Aviation organizations are replacing outdated systems to control maintenance operations.
∗ Maintenance areas are implementing support information processing technology as Computerized Maintenance Management Systems (CMMS).
∗ CMMS systems include algorithms automating the workflow.
∗ Rumors complicate the normal challenges during implementation. Change management should solve issues like problems with motivation and performance.
∗ Is there an age influence? First, an assessment is needed to evaluate opinions and factors influencing the opinions?
Introduction
∗ Assess the perception of people about age
influence on attitudes and performance of
maintenance employees in airline
organizations.
Objective
∗ A survey is elaborated to assess two aspects: attitudes and performance. ∗ Attitudes: confidence and excitement
∗ Performance, quantity of errors and completion time
∗ Respondents randomly selecting from different work areas within a typical maintenance organization (Line Maintenance, Quality Control, Materials, Engineering, Planning, etc.).
∗ Majority of respondents belong to the same company but some of the respondents work in the headquarters of the firm in a different country.
Methodology
Survey
Results
Question 1 Question 9
∗ Graph 2. Responses showing attitude respect confidence of workers over 50 years to use computer-based workflow processes
∗ Graph 1. Responses showing attitude respect confidence of young AMTs or engineers to do computer-based workflow processes.

Null Hypothesis
∗ From U-test tables @5% two tailed, Ucrit = 99
∗ U <= Ucritical?
∗ No, there is no significant difference between the answers
∗ Ho : There is not a significant difference between the answers provided for Q1 and Q9
Results
Question 1 Question 1

∗ Respondents believe young people is more motivated, interested, do less errors and finish sooner tasks in CMMS.
∗ They are consistent answering the related questions respect senior employees.
∗ Respondents are more neutral respect skills and motivation of seniors
∗ Previous experience is key according to respondents.
∗ These conclusions only apply to the population observed.
∗ 1. Age of the respondent is not a factor when agreeing or disagreeing with the statements.
∗ 2. Respondents were consistent with each pair of related questions. This conclusion is supported with the U-tests run.
∗ 3. There was not statistical evidence that work area is a factor influencing the level of agreement or disagreement. Again U-tests elaborated support this conclusion.
∗ 4. People were more biased to agree with responses favoring superior motivation and performance of young users of CMMS.
∗ 5. Respondents were neutral on attitudes respect skills and motivation of senior employees.
∗ 6. Previous experience using computers is an important factor, but more research is required to properly assess the impact or validity of such perception.
