Identifying the constraints of Software Engineering and ways of overcoming the constraints
In order to build new software, system developers come across certain constraints or limitations. The common types of constraints are related to the speed of the network, processor power, memory usage, etc. Again, design constraints are also present that might cause issues while developing a new system. Issues related to quality, resources, and schedule is present (Anderson, 2003). The constraints can be estimated roughly. For instance, if the delivery date is hard and resources are limited, it can have a direct impact on the quality of the system. Again, if one has to deliver the system within an unreasonable schedule, even the sufficient amount of resources will be effective. Therefore, other combinations can be considered, and the results would be similar.
In the case of designing software for mobile, a range of constraints should be considered so that the issues can be tackled effectively. Some of the notable constraints have been outlined below-
- Sensors, screen size, and interactions– The software developer must consider the fact that screen sizes are usually smaller, and limited canvas is available. Users must be able to use both hands while interacting with the software. Therefore, the developer must choose a block design, spatial format, or even a list format. While developing a Windows Phone or iOS, one must consider the screen resolution and its variations (Kyaruzi & Katwijk, 1999).
- Cache and storage size- The user can make a choice between downloading and storing content to use it later. This, in turn, would reduce the transfer of data in case of online transactions. The developer must consider storage availability in the internal memory or memory card. In the case of the memory card, the developer needs to tackle different states where the user can modify or delete content that is present in the memory card. In the case of internal software, the user has limited space for storage, and the risk of overwriting on cached data is present as well.
- Issues with the network- Network latencies along with failure points are common constraints while building software. The messages that display on the user’s screens, such as “connecting” or “try again” can be frustrating. The barrier can be overcome by avoiding blocking spinners. The platform can be designed in a manner so that users can remain occupied without the feeling frustrated. The user can have the liberty to pull the SIM card out and put it back whenever required. This, in turn, would affect the software of the device along with the backend supporting it (Rountev, Milanova & Ryder, 2001). Therefore, the failure points must be identified, and the avenues can be used so that the product’s personality can be shown.
- Requirements of data use- Apart from using the data connection, the SIM card provide information related to Mobile Network Code and Mobile Country Code. These features are used for identifying the country location of the user and the network connection. Based on the information, data requirements can be adjusted. Therefore, the data use constraint should be dealt with effectively.
