Core Values

WMO procurement adheres to the Best Value for Money (BVM) and furthers UN procurement general principles.  

1. Best value for money  

Best value for money can be defined as the most advantageous balance between:  

  • Compliance with the technical requirements  
  • Quality  
  • Cost, including total lifecycle cost when applicable  
  • Compliance with WMO standard contractual terms and conditions  
  • Warranties and long-term sustainability arrangements  
  • Economic, Social and Environmental considerations  

2. Fairness, integrity, and transparency  

  • Fairness essentially means that all bidders will receive equal opportunities, who will simultaneously receive the same information on a specific procurement exercise.  
  • Integrity substantially means adherence to commonly accepted moral and ethical standards.  
  • Transparency means that all relevant procurement information is clearly defined, made public, and/or provided to all interested parties and that procedures and rules are followed to demonstrate to all stakeholders that fairness is applied.

3. Effective competition

The principle of effective competition signifies that WMO will strive to foster competition by - among other things - providing adequate notification to the geographically largest vendor community and by avoiding restrictions to competition (e.g., through over-specification or under-specifications).

4. Sustainability

WMO is also firmly committed to advancing sustainability wherever feasible, and this implies that social, environmental, and economic considerations are increasingly and progressively taken into account when conducting procurement activities and exercises.
