Solution

1)

To design an interface for disablities. We need to follow accessibility design which is used to design applications for disablities.

First have to consider the type of user and for what purpose application will be used.

Based on the user and in that based on diablity we need to develop application.

For example,

For blind people to read SMS on mobile Speech recognization can be used and for deaf he can type message but cannot hear so when he types message it has go in a audio format i.e., text to speech converstion for making calls.

2)

Many factors can affect the chosen project development method of an organization or project team. When evaluating which approach to take, consider whether the project is familiar territory with a predictable path, or a new frontier with uncertain outcomes. Known projects can usally rely upon a predictive method of planning. Predictive planning provides a linear, specific development plan structured around producing a pre-determined end result within a specific timeframe.

Evolving projects that face changing conditions are best suited for adaptive planning. Adaptive planning involves breaking a project into small components over an undetermined timeline to allow ultimate flexibility in directing the course of the project. Whereas the outputs from predictive planning are expected and knowable, adaptive planning may yeild surprising outcomes. Due to the incremental nature of adaptive planning, the overall result of a project may differ substantially from original intent. The challenge associated with adaptive planning is to remain flexible and open to change, when not becoming irresolute.

The planning approach selected by an organization will lend itself to a specific project development methodology. Whereas an organisation with a predictive mindset might choose to utilize a Waterfall approach, adaptive teams may choose agile techniques.
