What is BS EN 16601-10 - Project planning and implementation of space projects about?  
The scope of BS EN 16601-10 is limited to describing the key elements of project planning and implementation and identifying the top-level requirements and products that together provide a coherent and integrated project planning across the 3 ECSS branches
BS EN 16601-10 has been developed to cover specifically space systems and has, therefore, precedence over any EN covering the same scope but with a wider domain of applicability (e.g.: aerospace).
BS EN 16601-10 may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
Who is BS EN 16601-10 - Project planning and implementation of space projects for? 
BS EN 16601-10 on project planning and implementation of space projects is useful for: 
- Spacecraft and space products manufacturers         
- Aerospace products manufacturers   
- Testing agencies involved in the inspection of spacecraft and aerospace products         
- Quality control personnel for spacecraft products      
- Aeronautical engineers 
- Space researchers
- Space project managers
Why should you use BS EN 16601-10 - Project planning and implementation of space projects?  
Project planning and implementation is the project function, encompassing a coherent set of processes for all aspects of project management and control.
Where other ECSS management, engineering, or product assurance standards contain more specific and detailed requirements related to project planning, references are provided to identify where these can be found within the ECSS system. This is done by:
- Establishing the project requirements and constraints derived from the mission statement
- Defining phases and formal milestones enabling the progress of the project to be controlled with respect to cost, schedule, and technical objectives (i.e., project control function)
- Defining project breakdown structures, which constitute the common and unique reference system for the project management to
- Identify the tasks and responsibilities of each actor
- Facilitate the coherence between all activities of the whole project
- Perform scheduling and costing activities
- Setting up a project organization to perform all necessary activities on the project
ISO 21502 guides concepts and practices for space project management that are important for and have an impact on a project’s successful delivery.
