The Gartner TIME model categorizes applications along two dimensions:

• Technical Fit — how well the application's technology meets current and future requirements (values: Fully Appropriate, Adequate, Inappropriate, Unreasonable)
• Functional Fit — how well the application meets the business needs it is intended to serve (values: Perfect, Appropriate, Insufficient, Unreasonable)

The combination of these two dimensions determines the TIME category:

• Invest — Technical Fit is Fully Appropriate or Adequate, and Functional Fit is Appropriate or Perfect
• Tolerate — Technical Fit is Fully Appropriate or Adequate, and Functional Fit is Insufficient or Unreasonable
• Migrate — Technical Fit is Inappropriate or Unreasonable, and Functional Fit is Appropriate or Perfect
• Eliminate — Technical Fit is Inappropriate or Unreasonable, and Functional Fit is Insufficient or Unreasonable

If either field is unset, no classification is written.

This extension requires the fields provided by the Portfolio Strategy extension to be installed in your workspace. Specifically, the following fields must be present on the Application fact sheet:

• Time Classification (lxTimeClassification): Tolerate, Invest, Migrate, Eliminate
• Technical Fit (technicalSuitability): Fully Appropriate, Adequate, Inappropriate, Unreasonable
• Functional Fit (functionalSuitability): Perfect, Appropriate, Insufficient, Unreasonable

The calculation runs automatically whenever Technical Fit or Functional Fit changes on an Application fact sheet. No manual trigger is needed.

The logic is:

export function main() {
    if (data.technicalSuitability === 'fullyAppropriate' || data.technicalSuitability === 'adequate') {
        if (data.functionalSuitability === 'unreasonable' || data.functionalSuitability === 'insufficient') {
            return 'Tolerate'
        }
        if (data.functionalSuitability === 'appropriate' || data.functionalSuitability === 'perfect') {
            return 'Invest'
        }
    }
    if (data.technicalSuitability === 'unreasonable' || data.technicalSuitability === 'inappropriate') {
        if (data.functionalSuitability === 'unreasonable' || data.functionalSuitability === 'insufficient') {
            return 'Eliminate'
        }
        if (data.functionalSuitability === 'appropriate' || data.functionalSuitability === 'perfect') {
            return 'Migrate'
        }
    }
    return null
