2.5 PRODUCT FUNCTION:

MAK/SKIT

Page 10


SKIT 25-02-2012

2.5.1 FUNCTIONAL REQUIREMENTS (OR PRIMARY FUNCTIONS) The system shall have an Internet connection. This will enable the downloading of songs from a digital media store. In addition, users shall be able to use a web browser in locating songs to download. The system shall allow a media server configuration. This will allow music in the library to be shared with compatible remote devices. Therefore, both the system and devices shall use a common networking protocol. In this user could access music located on their media player through a games console. As a result of this, the system shall restrict access to the shared network to those who have authorized access. The system shall communicate with distribution devices via a connection. This could be a wired connection or optionally a wireless connection.

2.5.2

NONFUNCTIONAL

REQUIREMENTS

(OR

SECONDARY

FUNCTIONS): 2.5.2.1 Performance Requirements The application must have a minimum processor speed so that there are some restrictions on what type of computer can use it. However this will be as small as possible to enable a broad range of clients to use the application. From Jonathon’s ethnographic study we can see that speed was a common issue while distributing music. The system must also aim to use minimum hard disk space yet keep the quality of the media as high as possible.

2.5.2.2 Safety Requirements All songs downloaded will be checked before downloaded by the system to make sure the music has no viruses in order to keep the user’s computer safe from being attacked. The next requirement is that a compressed version of the songs which are downloaded get saved to a back-up area so that if something goes wrong with the software like it crashes the song files are still safe.

2.5.2.3 Security Requirements

MAK/SKIT

Page 11


SKIT 25-02-2012

Information of users such as IP addresses will be kept private so that third parties cannot gain access to this personal information in order to keep within the Data Protection Act. The next requirement is that the system should prevent the user downloading material which would be deemed offensive such as blasphemy and obscene material and also the system will check certain age restrictions on songs to make sure that material isn’t seen by minors. The final limitation is that the method of which people share their music should have limitations so that Copyright of songs is not broken.

2.5.2.4 Software Quality Attributes These are a variety of constraints that might affect the user or system. The system should be able to by-pass security systems which are on the computer which deny our system connection. This is to enable that reliability is always at a high level; some ethnographic studies showed that users could not connected to the internet due to firewalls. The next requirement is that the application should enable music files to be converted to different, valid, formats and that all common music formats should be supported; any which aren’t are provided with plug-ins to enable them. This is to ensure interoperability between the files and system, the decision for this was that in numerous ethnographic studies the downloaded music couldn’t be played using their chosen device. Another interoperability requirement is that the system should allow any storage device to connect to the system and enable the distribution of music. The reason for this is that research shows people used ITunes but they could only distribute the music on to their IPods which was found to be a problem. A usability requirement is that there should be a help guide within the new system so that the time that new users can soon understand the system; however the system will be simple and therefore self-explanatory. There will be hotkeys throughout the system so that users can speed up their performance once they have mastered how to use the program. The system should remember the last song played on the system so that users can manipulate the program easily and efficiently. The system will have a predictive search where the user starts typing in the name of a song and the system brings up a variety of options which begin with the same parts as the search. The reason for this is that if the user see’s there search in the drop down box it saves them typing it out which may cause typing errors.

2.6 USER CHARACTERSTICS: The application is intended for users who use and distribute music electronically. One of the highest priorities is age verification; people under the age of 16 should not be allowed to purchase the songs online and adults may also chose to ‘lock’ specific songs which contain MAK/SKIT

offensive material. The application shall allow both novice users and more competent computer users to use the system effectively. For more frequent computer users, there will be options for advanced functions to allow them to generate their own playlists along with storing and loading multiple files. The system shall restrict remote users being able to download music on a clients system. The target clients for our software are ordinary computer users who distribute music media. It is assumed that the target group does not have to be familiar with the use of any software of similar functionality, but to have a basic computer and Internet skills that will enable them to use this software.
