Depending on the size of your organization and the business objective you are trying to achieve with your mobile app, you will need to account for the internal efforts involved with supporting and sustaining your app. Typically business functions such as IT, engineering, marketing, sales are instrumental to success.
IT and engineering play a key role in development, integration with other services, and ensuring any changes to internal systems function correctly. Even if you have chosen an external mobile app development partner, there will be people on your own team who will need to be involved.
Marketing, for the reasons mentioned earlier, also needed to drive user acquisition and growth, and for other tasks, depending on the type of app you’re developing. If you plan on doing any in-app marketing or promotions, marketing will be a large component in the strategy.
While the level of involvement of each department will vary depending on the nature of the mobile app, its goals, and its features, cross-departmental effort, and coordination are key to the success of your project. Even though the involvement will vary significantly from an enterprise company to a startup, cross-department involvement is always required.
