It is the process by which managers or executives acquire skills and competency in their present jobs and also capabilities for future tasks. GROUP FORMATION AND DEVELOPMENT by Phil Bartle, PhD Reference Document. The dependent variable is the measurable outcome of this manipulation, the results of the experimental design.For many physical experiments, isolating the independent variable and measuring the dependent is generally easy.. Human resource development is important for cultivating an engaged and motivated workforce and leads to superior business results. There are no rules about the structure and style for writing about independent or dependent variables but, as with any academic writing, clarity and being succinct is most important. The first and foremost process that has a remarkable place in this technology-driven world is software & system development, which is no doubt is becoming more and more crucial since the demand for software is steadily growing from every corner supposable. Yes, there is. A variable's scope is defined by where the variable is initialized or created. In fact, you should not. The positive effect of demographic variables on environment and development was rarely emphasized. Scientific experiments have several types of variables.
