 ## Project Overview
 
-Our team has been tasked with refining the overall service flow of **AlzGuard**, a digital therapeutic (DTx) and wellness application designed for individuals with **mild cognitive impairment (MCI)**.
-
-AlzGuard currently comprises four independent modules, collectively referred to as **DN**, where **N** indicates the test duration in minutes:
+The project centers on optimizing the service flow of **AlzGuard**, a digital therapeutic (DTx) and wellness application targeting individuals with **mild cognitive impairment (MCI)**.
 
-- **D5** and **D10**: Wellness-focused modules
-  - `D5`: A brief cognitive screening test (~5 min)
-  - `D10`: A longer test offering both assessment and personalized cognitive training
+AlzGuard consists of four independent modules, collectively referred to as **DN**, where **N** denotes the test duration in minutes:
 
-- **D20** and **D35**: Clinical-grade DTx modules, intended for hospital use
-  - `D20`: Early-stage diagnostic support, currently in clinical trials
-  - `D35`: Longitudinal monitoring and follow-up testing post-diagnosis

+- **D20** and **D35**: Clinical-grade modules for use in medical contexts  
+  - Designed for diagnostic support, currently undergoing clinical evaluation
 
-A major issue is that these DN modules were developed and released separately, leading to:
+Each module was developed in isolation, resulting in several critical issues:
 
-- Overlapping test content  
+- Redundancy in test content  
 - Fragmented user experience  
-- Lack of interoperability across services  
+- Limited interoperability across services  
 
-Our objective is to design a **cohesive service flow** that unifies these modules into an integrated experience. Specifically, we’re exploring how **wellness tools (D5, D10)** can connect meaningfully to **clinical DTx tools (D20, D35)** in a seamless continuum of care.
+The objective is to propose a **cohesive and scalable service flow** that integrates these modules into a unified user experience. Emphasis is placed on aligning wellness-stage tools (D5, D10) with clinical-stage tools (D20, D35) to ensure continuity of care.

 ## Early Work
 
-To ground our strategy, we first conducted foundational research on:
+Initial efforts involved foundational research in three key domains:
 
-- **National digital health policy** in South Korea  
-- **User segmentation** and personas based on age, tech literacy, and health status  
-- **Clinical characteristics** of MCI and dementia
+- Policy trends in South Korea’s digital health ecosystem  
+- User segmentation strategies based on age, digital literacy, and health status  
+- Clinical and cognitive dimensions of MCI and dementia
 
-During the first week, we focused on **hands-on product evaluation** and **desk research**.  
-We tested available DN modules (D5, D10, D35) on Galaxy Tab devices and evaluated their structure, flow, and UX to identify potential improvements and integration strategies.
+Product evaluation and structural analysis of DN modules (D5, D10, D35) were conducted using Galaxy Tab devices. Focus was placed on assessing flow logic, interface usability, and potential points of integration across modules.
