Yes it still harmful because it is air pollution to your lungs. My kid's pediatrician used to tell me that I should change my clothes after smoking a cigarette and before I carry my baby.
In Scrum, a product backlog item (PBI, backlog item, or item) is a unit of work small enough to be completed by a team in one Sprint iteration. Backlog items are decomposed into one or more tasks. See also backlog effort estimation unit.
PBI stands for programme budget implication. A PBI is a statement detailing the administrative, financial and programmatic changes that the adoption of a draft resolution would entail. Once a PBI is issued, ACABQ will also provide its observations for the Fifth Committee to consider. At least 48 hours are required before action can be taken on a draft resolution containing budgetary implications so that the Secretary-General can prepare the PBI and ACABQ can consider it.
