The idiosyncratic trajectory of literature review for MBA dissertation projects on a single case study

The idiosyncratic trajectory of literature review for MBA dissertation projects on a single case study [in the agile literature review approach]:

Let us consider the following high-level research task (in the agile literature review approach [ALRA]):

To evaluate the managerial competence to retain staff in the sales department of ABC Ltd.

Ltierature review effort : from the general and broad themes (High level focus) to the idiosyncratic themes (Low level focus)

High level focus

Level 0: The human resource management function, with special reference to staff retention.

Level 1: The managerial competence with special reference to staff retention.

Level 2: Staff retention competence of salespeople from the perspective of levels 0 and 1.

Level 3a: Staff retention competence of salespeople in SMEs (ABC Ltd being an SME) from the perspective of levels 0 and 1.

Level 3b: Staff retention competence of salespeople in the interior design sector (ABC Ltd being an interior design company) from the perspective of levels 0 - 2.

Leve 3c: Staff retention competence of salespeople in Hong Kong from the perspective of levels 0 - 2.

Level 3d: Staff retention competence of salespeople in the context of covid 19 from the perspective of levels 0 - 2.

Level 4: staff retention competence of salespeople of HK SMEs in the interior design sector in the context of covid 19.

Level 5: level 4 with additional idiosyncratic considerations of ABC Ltd. (may have to do with company-specific internal and external organizational factors, such as peculiar executive personalities/ values and family business culture).

Low level focus

** Literature search with higher level focus is easier than that with lower level focus. Kindly also study the literature review funnel for enhancing knowledge on the idiosyncratic trajectory of literature review.

Now, As you go through the idiosyncratic literature review trajectory (e.g. from level 0 to level 5), take stock of what (i) academic theories, models and notions [including their definitions], (ii) research questions and research methods raised, and (iii) empirical findings have been identified by you as useful to inform your high-level research task: 

        "To evaluate the managerial competence to retain staff in the sales department of ABC Ltd", or "To evaluate the HRM competence of ABC Ltd, with special regard to staff retention of salespeople".
