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.

Requirements

Functional

'Users'

• Users should be able to subscribe to paid services
• Users should be able to scan their computer and check for installed programs
• Users should be able to gain information on these installed programs through us (WPE)
• Users should be able to delete the application
• Users should be able to request suggestions on alternative
• Users should be able to search for similar applications
• Users should be able to search for any application
• Users should be able to submit their rating/opinion to be reviewed by us

'Companies'

• Companies should be able to apply for verification
• Companies should be able to submit their own description after verification

Non-Functional

• Application shall be operable in offline environment
• All the application details shall be as transparent to user as possible
• Every aspect of the software shall be testable
• User experience of the software shall be as responsive as possible
• User privacy shall be completely protected
• Documentation of software shall be easily understood by new developers
• Backend infrastructure should be scalable
• Software shall be safe to operate by non technical people
• Application shall be intuitively operable by 70 year old with minimal technical knowledge

User Stories

• User needs to find specific information on an installed application, enters name into search bar and presses search-button.
• User finds application, selects it and presses view detailed information button.
• User sees no specific details about application and presses "request additional information"-button.
• User looks through provided information, wants to remove the application and presses the "uninstall"-button, confirmation dialogue appears and user confirms his decision.
• User wants to find possible similar applications, presses "similar apps"-button.
• Premium user sees notification presses it and opens up a tab with an active analysis of host system.
• Non-premium user wants to get premium-features, switches to premium-features section which displays features and payment information.
• User selects preferred amount and payment method from premium-features section which opens up an external browser with preferred payment method's website.
• User wants to change how application updates, opens the update options from the settings menu and selects the "ask-for-confirmation-before-update" method.
• User wants to install a program and check whether the developer is verified or not so searches for the verification signature in the application details.
• User wants to leave feedback on specific application, clicks "leave feedback" button in the application information details tab that opens up a text-box, the user enters feedback and presses submit button.

Object Oriented Approach

Objects

• User (Bob) -> E-mail -> Submit request / Premium features / Inspect Installed Applications / Give Feedback / Submit Description on Application -> Verified/Unverified/Registered/Unregistered/Premium/Standard

• Application (Notepad) -> Name + Version -> Text-Editing -> Installed/Uninstalled/Running

• Devteam (Peep) -> CompanyID -> Verify Application Descriptions and Issue updates -> Working/On Holiday

• App owners (Microsoft) -> Company Name -> Submit detailed on owned Application -> Verified/Unverified/Bankruptcy

• Request (Request detail on Notepad) -> Unique request ID -> Query internal App database / Query Windows / Contact server -> Pending/Idle/Denied/Accepted/Finalized

• Report (Report on Notepad) -> Unique report ID -> Return application detailed information -> Delivery Origin/Successful/Failed

Actors

• Customer -> Obtain detailed app information / Pay subscription / (Un-)Install application / Find applications
• Developer -> Develop features / write code / Analyze / Design
• Application Owner -> Get verified / Provide information on Application(s) / Gain users

User-Stories

• Non-premium user wants to get premium-features, switches to premium-features section which displays features and payment information.
• Premium user sees notification presses it and opens up a tab with an active analysis of host system.
• User wants to install a program and check whether the developer is verified or not so searches for the verification signature in the application details.
• User finds application, selects it and presses view detailed information button.
• User wants to find possible similar applications, presses "similar apps"-button.
