+# ADR: We implement domain services static
+
+Domain services can be implemented either as object (and composed like done in spring / example1 ) or with extension 
+function and composed static (see example2).
+
+## example1
+```kotlin
+class DesktopServie(val aptApi: AptApi, val prov: Prov) {
+    fun provisionIdeDesktop(onlyModules: List<String>? = null) {
+        prov.task {
+            if (onlyModules == null) {
+                aptApi.aptInstall(OPEN_VPM)
+            }
+        }
+    }
+}
+```
+
+## example2
+```kotlin
+fun Prov.provisionIdeDesktop(onlyModules: List<String>? = null) {
+    if (onlyModules == null) {
+        aptInstall(OPEN_VPM)
+    }
+}
+```
+
+## Decission
+
+We use extension function and composed static.
+
+## Reason
+
+1. Similar to composed objects we can easily mock `aptInstall` in tests. Both solutions are equivalent.
+2. Inheritance in case of composed objects we can solve by static composition.
+3. Object composition we can solve by static composition.
+
+There is no reason left to change the current implementd pattern.
