IT SWOT

Strength Weakness Opportunities Threats
Innovative - no other popular program like this No brand recognition Globally extending Larger company might sprint past with a similar program
Strong team - well organized, good Small company not a lot of financial backup Expand the team for faster development Sustainable financial backing
Competitively priced Development slow due to the size of the company Targeting industries Customer scepticisim - do not want to give access to scan their computer
User-friendly interface Organic growth - no outside funding

Improvements

Problems:

  • Application Information
    • Due to lack of program information / Methods of updating
    • Trustworthiness / Unknown Sources
    • Customer Perception of the Products [Solution should provide: Transparency for customers / Awareness of Application]
  • Market access / interactions


Short Information System Description

Information System will provide Windows OS users with detailed information on their installed packages and applications. Provided information will include trustworthiness / rating / availability / checksum / developer details of the application. System will incentivize users and developers to submit descriptions of applications, which would go through a review process before publication. Companies can become verified by us through a paid application verification process thereby granting "trust-ability" to these applications and their developers. Users can subscribe to a live-scanning service which will notify them when any installed packages are compromised or need to be updated.
