**7. Conclusion**

To summarise, this research achieved an analysis on 221 samples to investigate two outcomes:


For interpretation, the literature review identified the essential HR determinants of engineering consultants to be knowledge, experience, motivation, professionalism, and the care factor. Following this, a set of hypotheses were formulated to highlight that these factors had a positive and direct effect on client satisfaction. A questionnaire was designed and distributed to various clients of an engineering consulting firm in Sydney, Australia; the response rate was 35% with a sample size of 256 and 221 valid responses were collected. Namely, it was discovered that due to high squared multiple correlations of the endogenous variables, there was enough statistical power to support the significance found for each HR determinant's impact on client satisfaction.

Thereafter, an extensive Exploratory Factor Analysis (EFA) of the data found that the questionnaire items loaded as expected to the original HR determinants. After a review of the questionnaire items and the data results, a Confirmatory Factor Analysis (CFA) and a Path Analysis were performed on the model that exhibited sufficient-togood reliability, validity, model fit, and squared multiple correlations. These findings

correspond with [6] who stressed the importance of the "unwritten expectations" that clients desire but do not clearly state.

In conclusion, Engineering Consulting Firms that can guarantee client satisfaction are more likely to retain those clients as well as receive recommendations that help them gain new clients. Specifically, it should be highlighted that experienced, knowledgeable, and motivated employees will always have the greatest and most desired impact on client satisfaction. Without a doubt, these firms should not only be aware of but also acknowledge that when their employees are satisfied, this will translate into satisfied clients and ensure satisfactory end products.
