Why App Projects Go Wrong
Custom app projects fail predictably. Vague requirements lead to different expectations. Scope expands as "simple additions" accumulate. Edge cases consume more time than core features. Good scoping prevents most of these problems.
Define the Problem First
Before discussing solutions, clearly articulate the problem.
Current state
What happens today? What is the process? Where does it break down? What manual work is involved?
Desired state
What should happen instead? What does success look like? How will you know the app works?
Quantify the impact
How much time does the current problem cost? How much revenue is at risk? Quantification helps prioritize and justify investment.
Define Minimum Viable Functionality
Start with the smallest useful version.
What must the first version do?
Identify the core functionality without which the app has no value. This is version 1.0.
What can wait?
Nice-to-have features, edge case handling, and polish can come in subsequent versions. Do not bloat the initial scope.
The 80/20 rule
Often 20% of functionality delivers 80% of value. Identify that 20% and build it first.
Specify Data Flows
Data movement is where complexity hides.
What data enters the app?
Where does data come from? Shopify? External systems? User input? What format? How frequently?
What data leaves the app?
Where does data go? Back to Shopify? To external APIs? What format? What triggers the output?
What happens when things fail?
API timeouts, invalid data, partial failures. How should the app respond? This is often more complex than the happy path.
Define the User Experience
If the app has admin UI, specify it clearly.
Who uses the app?
Shopify admins? Customer service? External partners? Different users have different needs.
What actions do they take?
List specific actions: configure settings, view reports, trigger manual sync, review errors.
Wireframes or mockups
Visual specifications prevent misunderstandings. Even rough wireframes communicate intent better than words.
Identify Unknowns
What do you not know yet?
Technical unknowns
Can the external API do what you need? Are there rate limits? Is data available in the required format?
Business unknowns
Are requirements stable? Will processes change? Are stakeholders aligned?
Plan for discovery
Include time and budget for investigating unknowns. Discovery work reduces risk before committing to full development.
Structure Contracts to Manage Risk
How you engage affects risk distribution.
Fixed price with clear scope
Works when requirements are well-defined. Changes require scope adjustments.
Time and materials
Flexible but less predictable. Works for discovery-heavy projects where requirements will evolve.
Phased approach
Discovery phase (fixed), development phase (fixed or T&M), iteration phase (T&M). Reduces risk by providing decision points.
Success Criteria
Define how you will know the project succeeded.
Acceptance criteria
Specific, testable conditions that must be met. "Orders sync to ERP within 5 minutes" is testable. "Integration works well" is not.
Performance requirements
Response times, throughput, reliability targets. Vague performance expectations lead to disputes.
For app development, see custom Shopify apps.
Working with LiftKit Digital
LiftKit Digital invests in scoping before development. Clear scope leads to predictable projects. We would rather spend more time defining requirements than fixing misaligned expectations.
