Knowledge is still considered to be power and its externalization makes it possible for others to use that power. In this paper, we examine the theory of brainstorming, and the claim by father Alex Osborn that in a group session an individual can think of twice as many ideas than working alone. In the context of requirements elicitation, we performed an experiment on a “nominal” and a “real” group of participants, following a procedure based on the Jaccard index. However, the obtained results do not provide evidence to support the above opinion, because during a five-minute session, participants working individually produce over 43% more ideas than a group of different participants.

Wiedza jest ciągle postrzegana jako źródło siły, zaś jej ekternalizacja czyni ją dostępną dla innych. W niniejszym artykule poddano rewizji teorię burzy mózgów, w szczególności założenie jej Autora Alexa Osborna, że w trakcie sesji grupowej (realnej) pojedyczny uczestnik wygeneruje dwa razy więcej myśli (idei) niż w trakcie samodzielnej (nominalnej) sesji. W kontekście pozyskiwania wymagań został przeprowadzony eksperyment na grupach nominalnych i realnych. Do porównania otrzymanych wyników wykorzystano indeks Jaccarda. Otrzymane wyniki jednak stoją w sprzeczności z powyższym stwierdzeniem, pokazując, że o 43% więcej idei wygenerowały pojedynczy uczestnicy badania w porównaniu do ich grup.

An orphaned child, who has no more opportunity for growth and development in its biological family, is often sent to an orphanage, or another residential institution devoted to this type of care. Children who in the beginning of their childhood are raised in these institutions do not always have a chance for good development because places like this are not always able to meet the children’s most important needs. Institutional upbringing often only consists of meeting their basic needs such as proper hygiene and providing food, but this is not enough to promote a proper physical, social or cognitive development of any child. For a proper development, the child psychological needs need to be satisfied and this is required for its well-being. These can only be maintained by providing security, love, belonging and an emotional contact with another person. All these needs can only be provided and guaranteed by a healthy family environment. For an orphaned child, the lack of its own family can only be compensated by an adoptive family. Adoption is the best form of care whereby a family assumes the parenting for another and, in so doing, permanently transfers all rights and responsibilities, along with fi liation, from the biological parents. Adoptive families are the closest in its form to a biological family, and should be the most valued mean of tackling the problem of orphaned children in our society.
