Describe blitz modeling as a unit of sizing of software.- Blitz modelling is an approach for software estimation which uses number of classes and number of programs per class as software metric. This technique is completely based upon historical data and hence historical database is essential.
- It gets better with each passing phase as the database becomes more and more accurate. Blitz modelling technique segregates and calculates function strong and data strong systems.
- It is easy to use with object oriented techniques and accuracy increases along with the historical database. The main disadvantage is that it uses design methodologies and estimation thus cannot begin until the design is complete which is not always possible.
