BACKGROUND

Please describe your company and position.

I am the Managing Director of Bawaria Motors sp. z o.o.

Describe what your company does in a single sentence.

Bawaria Motors is a dealership that specializes in selling and servicing BMW/MINI vehicles.

OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire EFFECTIVENESS INC to accomplish?
I was looking for solutions to support team management, to be used in all HR processes, from recruitment through daily cooperation (improving the quality of our interaction) to employee development. My goal was to gain skills in working with competency assessments, which would provide reliable information about personality differences, give insights into how to collaborate with people of different communication styles, values, and motivations. I wanted the solution to be both accurate and simple, so that my managers could learn to use it.

How many teammates from EFFECTIVENESS INC were assigned to this project?

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

Our collaboration began with the DISC D3 certification. The training I participated in provided me with knowledge about the behavior model, and I gained the skill of interpreting competency assessment results in terms of selecting the right person for the team, better understanding of employees' needs related to daily cooperation, constructive approach to difficulties that arise in interaction, and areas for employee development.
The DISC D3 assessment helped me develop as a leader and consciously select people for the team and then manage that collaboration. Individual employees in my team conducted the DISC D3 assessment, and then we participated in a series of webinars aimed at better understanding how personality affects teamwork, which personality elements to consider when hiring the right person, and how to interpret the results of the DISC D3 assessment to use this information to increase effectiveness in one's role. Personally, I participated in many other meetings and trainings conducted by EFFECTIVENESS, aimed at developing skills in using DISC D3 in various HR processes.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

In recruitment, we introduced an additional stage of candidate selection in terms of soft skills, attitude, fit for the role, team, and organization. Hiring the right people reduces recruitment and onboarding costs, and it affects the reduction of turnover in the team and increases the level of employee engagement. We also observe a higher level of communication in the team, considering differences in communication styles

Describe their project management. Did they deliver items on time? How did they respond to your needs?
