The ISO/IEC 25010 standard provides consistent terminology for “specifying, measuring and evaluating system and software product quality”.¹⁾ The Consortium for IT Software Quality (CISQ) ²⁾ provides the following diagram, highlighting eight ISO defined software quality characteristics and their associated sub-characteristics.³⁾ These ISO defined characteristics need to be applied to both DIDO software and coinage organizations (i.e., Bitcoin, Ethereum, Iota, etc), especially Reliability, Performance Efficiency, Security and Maintainability, since these are candidates for automation.

• square_plan
• 9000_sw
• 9000_qual

Modelling is part of SQuaRE and provides detailed quality models for computer systems and software products, quality in use, and data.

• square_sys_model
• square_data_model

Measurement is part of SQuaRE and includes a software product quality measurement reference model, mathematical definitions of quality measures, and practical guidance for their application.

• square_measure_model
• square_measure_element_model
• square_measure_in_use
• square_measure_product

Requirements are part of SQuaRE and help specify quality requirements. These quality requirements can be used in the process of quality requirements elicitation for a software product to be developed or as input for an evaluation process.

• square_qual_rqrmts

Evaluation is part of SQuaRE and provides requirements, recommendations and guidelines for software product evaluation
