Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
Thus a truecolor PNG is typically larger than a color-reduced GIF, although PNG could store the color-reduced version as a palettized file of comparable size. Conversely, some tools, when saving images as PNGs, automatically save them as truecolor, even if the original data use only 8-bit color, thus bloating the file unnecessarily. [ 55 ]
The first microcomputer-based presentation software was Cromemco's Slidemaster, developed by John F. Dunn and released by Cromemco in 1981.

This program allowed users to choose from a library of images to accompany the ...
The relationship between the size of software and the effort required to produce it is called productivity. For example, if a software engineer has built a small web-based calculator application, we can say that the project effort was 280 man-hours. However, this does not give any information about the size of the software product itself ...
