Développeur Sénior Power BI - Dynamics 365 CRM

The Role

The Power BI Developer designs and delivers reliable, business-oriented dashboards and KPIs based primarily on Dynamics 365 Sales and Customer Service data. The role requires the ability to understand business needs quickly, then translate them into KPIs, and deliver results efficiently.

• Understand the D365 data model (and underlying business models).

• Design Power BI semantic models and dashboards.

• Define and implement relevant business KPIs. Three existing sources will be considered:

1. Existing PowerBI “Sales Pulse” dashboard, already developed by the CRM Development Team, that could be considered as a functional & technical starting point for new Dashboards

2. Ambitious KPI roadmap designed by the Business Owner, that will be used as a mock-up, with the necessity to identify priorities and development releases

3. Detailed assessment done by the CRM team (business & IT) about one key KPI dealing with 5-years Sales Forecast, mixing different Sales Data (from short-term won Quotes, to mid-Terms pending Opportunities, to Long Term “Value-Creation Plan” and “Market Traction analysis on Business as-usual”: The Senior PBI developer will have to understand then master these business concepts, for efficient Business need translation into KPIs).

Execution efficiency is key, as some KPIs must be operational at the end of October (Development deadline), to be finalized then demonstrated during the Yearly Group Convention (mid-November). The capacity to properly estimate and manage the execution timeframe is a must-have, as there must be no delay. 

“Design to planning” approach must be considered right from the start.

Commitment taken must be respected, considering the deadlines.
