ABSTRACT Objective: to evaluate functional performance and technical quality of user embracement software with pediatric risk classification. Method: descriptive exploratory study developed based on the quality requirements set forth in ISO/IEC 25010. The evaluated characteristics were: functional adequacy, reliability, usability, performance efficiency, compatibility, safety, maintainability and portability. Eight specialists from the area of informatics and 13 from nursing participated in the evaluation. The characteristics were considered adequate when they reached more than 70% of indication as very and/or completely appropriate in the evaluations of each group of specialists. Results: The results obtained from the evaluation of informatics and nursing specialists were: functional adequacy (100.0%, 96.2%), reliability (82.6%, 88.5%), usability (84.9%; 98.7%), performance efficiency (93.4%; 96.2%), compatibility (85.0%, 98.1%), safety (91.7%, 100.0%), and, yet, maintainability (95.0%) and portability (87.5%) evaluated by the first ones. Conclusion: the software was considered adequate regarding technical quality and functional performance.

Purpose The purpose of this paper is to perform a quantitative analysis of the literature in order to determine the main causes of delay in construction projects. Design/methodology/approach A set of 47 articles from the literature were analyzed, yielding 1,057 different causes of delay. In order to analyze and compare the main causes of delay, their degree of impact was studied statistically. Next, a mention count method was used to determine the primary causes of construction project delays and through the use of Pareto diagrams, the main causes of delays in construction projects were determined. Findings It was determined that the three main causes of construction project delay are problems that occur during execution, administrative problems and labor conflicts; together they account for almost 80 percent of the causes found in the literature. Moreover, it was deduced that problems during execution are based on unpredictable events, while administrative problems are rooted in poor cash flow management. In addition, seven sub-groups of delay causes were identified as being major due to the number of mentions detected. These were “Changes during construction,” “Poor construction management,” “Construction errors,” “Economic/Financial,” “Conflict/Relationship” and “Lack of experience.” Practical implications This study provides a unique classification method, which was successfully validated, for the causes of construction project delay. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing the appearance of unforeseen events during construction. Moreover, the results of this study will help project managers be aware of the possible causes of delay that may affect their construction projects. This understanding can help them identify potential risks in the initial phases of the project and allow decisions to be made early before problems arise or the consequences of the deviations become irreparable. The results can also serve as input for the development of future management improvement methodologies that are aimed at reducing costs and ensuring that deadlines are met. Social implications Identifying the factors and causes of the delays will allow mitigation actions to be taken in order to avoid delays, which will ultimately allow homes, schools, hospitals and other necessary infrastructure to be delivered on time or even before the planned date. Originality/value This study provides a unique classification method that was successfully validated. Thanks to the classification, designers may use this information as a starting point for designing future construction projects, thereby minimizing unforeseen events during construction.
