The document presents the results of a survey assessing perceptions of how age influences attitudes and performance when using Computerized Maintenance Management Systems (CMMS) workflow processes. The survey was administered to maintenance employees across different age groups and work areas. The results showed respondents believed young people are more motivated, interested, make fewer errors and finish tasks sooner in CMMS. Respondents also remained consistent in their answers for related survey questions. No significant influence of work area or age was found. Respondents were neutral on attitudes toward skills and motivation of senior employees. Previous computer experience was seen as an important factor but requiring more research.

3. Introduction
∗ Aviation organizations are replacing outdated systems to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?

4. Objective
∗ Assess the perception of people about age
influence on attitudes and performance of
maintenance employees in airline
organizations.

5. Methodology
∗ 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.

15. Conclusions
∗ 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.
