Small Industries

The Small Industries Enterprise (SME), which is especially involved in the liquid filling industry (such as mineral water, tea, liquid milk, juice, etc.), needs some device that has the ability to measure liquid automatically and accurately into some container. Based on the 'Water Fall' method, this study carries out a procedure for making compact and efficient tools ('requirements definition' stage), using a keypad start button, flow sensor, temperature sensor, fan, buzzer, LCD 1602, relay driver ('system & software design' stage), implement a schematic drawing of the circuit and install all hardware inside the casing ('implementation and unit testing' stage), install accessories, set parameters and volume target ('integration and system testing ' stage) and re-calibrate the device ('operation and maintenance' stage). After the measurement experiment, we got that Fillco (the name of the device) has a bigger error for measurement below 1000 ml (0.6-15%) and better accuracy measurement for targeted volume upper than 1000 ml (0.04-0.20%). Fillco also able to memorize and reset liquid volume.

In The Beginning

This chapter discusses typical collaborative requirements definition processes as they are performed in open source software development (OSSD) projects. In the beginning, some important aspects of the entire OSSD approach are introduced in order to enable an understanding of the subsequent description of the feedback-based requirements definition processes. Since the OSSD model seems to represent a successful way of dealing with the significant distribution and heterogeneity of its actors, some opportunities to adapt this approach also in other (software) industries are discussed. Nevertheless the entire OSSD model still exhibits several improvement opportunities that also are addressed in this chapter. In order to overcome possible weaknesses, several approaches to improve the described requirements definition approach are introduced. These improvements help to assure a higher level of efficiency and quality assurance for both processes and the developed artifacts, and furthermore also enable the consideration and acceptance of this approach in other domains and industries.
