    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others as members of a team, group, organisation or community.
  • Note: The learner demonstrates the understanding that in a mining production environment effective teamwork is of utmost importance in working safely and productively. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively.
  • Note: The learner demonstrates understanding that activities, tools and equipment have to be managed effectively in the often isolated mining working environment. 

  • UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written presentations.
  • Note: The learner demonstrates the ability to communicate effectively with co-workers in the mining working environment, in which team members are dependent upon each other.
