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.
