The evaluation of Maintainability, a software product quality characteristic defined in ISO/IEC 25010, allows to know the degree of effectiveness and efficiency with which a product or system can be modified to improve it, correct it or adapt it to changes in environment, and in requirements.

The evaluation of Functional Suitability, another software product quality characteristic defined in ISO/IEC 25010, allows to know the degree to which a product or system provides functions that meet stated and implied needs when used under specified conditions. This way, it is evaluated whether the software product implementation is complete, correct and adequate regarding its functional specification.

The evaluation of Data Quality, based on the data quality characteristics defined in ISO/IEC 25012, allows to detect weaknesses in the data managed by an organization based on the following criteria: Accuracy, Completeness, Consistency, Credibility and Currentness. This way, it is evaluated the degree to which the data:

  • has attributes that correctly represent the true value of the intended attribute of a concept or event in a specific context of use.
  • has values for all expected attributes and related entity instances in a specific context of use.
  • has attributes that are free from contradiction and are coherent with other data in a specific context of use. It can be either or both among data regarding one entity and across similar data for comparable entities.
  • has attributes that are regarded as true and believable by users in a specific context of use. Credibility includes the concept of authenticity (the truthfulness of origins, attributions, commitments).
  • has attributes that are of the right age in a specific context of use.

The product Mediciones Certificadas 1.0, developed by Trecone (Treconite S.L.), has been granted the ISO/IEC 25000 certificate for Functional Suitability.

Certificate for Functional Suitability Trecone

Mediciones Certificadas 1.0 is an application that allows the user to test some aspects of the service provided by the carrier, and obtain evidence that supports a possible complaint against said carrier. These tests are related to mobile signal coverage (minimum required threshold, based on the location of the user), call recording (with information on the number called, date, time...) and information about calls made through the home network (national coverage) and those made through a visited network (roaming).

With this certificate, Trecone can assure their customers that their product complies fully and correctly with the functional requirements described for the product, thus obtaining an improvement in confidence and customer satisfaction.

In addition, this certification has helped Trecone Singular Apps to reduce maintenance costs, meet delivery times and detect defects in the software product before its delivery to the customers.

The certificate has been issued by AENOR taking the evaluation carried out by the accredited laboratory AQCLab as a basis. The issuance of the new certificate for functional suitability reflects the increased interest in software product quality, and more specifically, in the certification of quality characteristics conforming to ISO/IEC 25000.

AENOR and AQCLab delivered the first ISO/IEC 25000 certificate for Functional Suitability to the product BitRRHH 1.0, developed by Bitware, which reached the highest quality level (5 out of 5). With this certificate, Bitware guarantees their customers that their product BitRRHH 1.0 meets the functional requirements specified for the product in a correct and complete way, thus improving customer trust and satisfaction.

Among other advantages, this certification helps to improve software development and reeuce maintenance costs, ensuring that delivery times are met and detecting defects in the software product,  before its delivery. Consequently, it allows software developing companies to differentiate themselves from the competition.

For the certification of software product quality, AENOR collaborates with AQCLab, the first laboratory in Spain accredited by ENAC (Spain’s national accreditation body) to carry out software product quality evaluations conforming to ISO/IEC 25000, centered in the functional suitability and maintainability characteristics.

To issue this certificate, AENOR evaluates the report elaborated by the laboratory regarding the quality of the software product in question, and if this evaluation is satisfactory, AENOR checks the viability, the resources and the technical capabilities of the company that developed the software product. Once this process is finished, AENOR issues a certificate of conformance to ISO/IEC 25000.

According to ISO/IEC 25010, Functional Suitability is defined as the degree to which a product or system provides functions that meet stated and implied needs when used under specified conditions. Thus, Functional Suitability can be understood as the degree to which a product or system provides the necessary functions to meet the needs and conditions identified and explicitly specified during its analysis and design.

Functional Suitabiblity evaluation provides the following benefits:

  • Assuring that clients' needs are met.
  • Reducing bugs and defects found once the product is deployed.
  • Improving your clients' trust and satisfaction.
  • Being able to get a product certification that improves your competitiveness.

With a Functional Suitability certificate, software development companies can prove that their products meet all the requirements of their customers, and in turn, the clients are assured that the products they buy are functionally complete and correct.

With the Functional Suitability certificate, AENOR expands the catalogue of its software certification service, which already included the Maintainability characteristic, and which is planned to continue expanding through the collaboration with the laboratory AQCLab.

The September 2015 issue of the Quality Progress magazine, edited by ASQ, features the article “A Hard Look at Software Quality”, which describes how AQC Lab and AENOR conducted a pilot program to evaluate, improve and certify the quality of software products taking the ISO/IEC 25000 series of standards as a basis. A summary of the article is presented below, and through this link you can find an excerpt from the article provided by the laboratory AQC Lab.

Quality Progress September 2015

Since software quality is a key element for organizations because of its impact on final costs, evaluating and controlling it is becoming more and more important, especially when it takes direct evidence of a product’s own attributes as a basis.

The standards in the ISO/IEC 25000 series provide a framework for the evaluation of software product quality. This family of standards was used in a pilot program for the evaluation, improvement and certification of software product quality conducted by AQC Lab, AENOR, and several development companies from Spain.

The evaluation followed the process defined in ISO/IEC 25040, and the quality model defined in ISO/IEC 25010 was taken as a basis. Among the quality characteristics defined in ISO/IEC 25010, the pilot program focused on Maintainability, and its evaluation was carried out by means of several quality properties of the source code, such as cyclomatic complexity, code documentation, code structure, duplicate code, or violation of coding rules.

To evaluate the maintainability and its quality properties mentioned above, AQC Lab used a framework consisting of a set of measurement tools, an evaluation tool that integrates and aggregates the values provided by the measurement tools, and a tool for visualizing the results of the evaluations.

The software product quality certification process takes the evaluation carried out previously by the laboratory as an input. After checking the results of the evaluation and visiting the interested organization, the certification body issues the certificate if applicable.

The development companies that took part in the pilot program highlighted the reduction in maintenance effort and costs, the improvement in the execution and load speed of applications, and the incorporation of quality evaluations in their development life cycle as positive results from the experience.
