This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
People credited with this unit standard are able to:
  • Describe different approaches to problem solving
  • Use logical operations in descriptions of rules and relationships in problem situations
  • Simplify Boolean expressions with Boolean Algebra and Karnaugh maps
  • Describe the basic concepts of error detection
    The performance of all elements is to a standard that allows for further learning in this area. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit value of this unit is based on a person having prior knowledge and skills to:
  • Demonstrate understanding of Mathematics, at least at level 3.
  • Apply problem solving strategies

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    The relevant Education and Training Quality Authority (ETQA) must accredit providers before they can offer programs of education and training assessed against unit standards

    Moderation Process:
    Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    1. Performance of all elements should be performed with a solid understanding of the use of development tools needed in the areas applicable to the unit standard. Examples of such tools are, but is not limited to CASE tools, programming language editors with syntax checking, program source version control systems.
    2. Performance of all elements should make use of International capability models used for Software Development. Examples of such models include (but are not limited to) the ISO SPICE model as well as the CMM model for Software Development.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
