Field Force Management Integration Interface FFMII provides a flexible interface between ERMS and FFMS for the purpose of work request modeling, exchange, and collection of data from the field. Information carried with work requests, work request structure (work-flow) and data to be collected can all be defined dynamically ‘as data’. This data driven architecture makes FFMII very flexible and adaptable to numerous industries Rossum, NSN, Click. Software Technologies, Aalto, Newelo, Pajat Management 2

Design Goals & Characteristics • • • Applicability across domains and use cases Technical scalability Feature scalability Expression accuracy and user guidance Reliable message exchange Deployment adaptability and technology neutrality

Example Use Case: Telecom installation • Installation company receives installation jobs from several telecom operators • Work Request structure and reporting requirements vary – Order details, instructions, process flow, products and parts – Resolution codes, on-site sales and exception reporting • Single job may involve several locations – distribution points, cross-connections, end-user premises • Single installation may be split to several assignees • Information sharing among Field Force • Field-Initiated Requests – find available work, reserve job to me, initiate new job 4

Work Request Manager produces series of self-contained Work Requests representing Tasks related to Field Works. Each Task is to be performed by one or more Assignees belonging to the addressable Field Force. A Manager communicates with one or more Implementations over the FFMII interface to make the planned Tasks accessible to corresponding Assignees. 12

Work type Specification structure A Work Type Specification (WTS) describes content and structure of a Work Request 14

Relationship of Steps, Actions and States within an Activity A combination of States, Steps and Actions form an Activity State Model. FFMII interface does not prescribe or imply usage of any specific Activity State Model in order to remain neutral with respect to types of Task a Work Request may represent. In this example, the On. Site state requires the Assignee to decide whether the Task may be fulfilled by repairing the customer's equipment, or whether it is necessary to replace the equipment with a new unit. Action: Transition to On. Site Action: Repair Action: Transition to X-Finalize Therefore there are two possible actions leading from Step 2, and both of them are enabled so that the Assignee may select either of them (enabling conditions aren't visualized in this diagram). If the Assignee chooses the Replace action, the action leads to Step 4. In this example, replacement requires approval, so the dashed action transfers the task to an Inactive state, pushing the current State into the State Stack. At that point, the other action leading from Step 4 is not enabled, due to an enabling condition which depends on receiving the approval. Once the approval arrives, the next action pops the State Stack to return to the On. Site state. Action: Replace Action: Transition to X-Finalize Note: a more complete scenario would probably also include action that should lead from Step 5, for handling the case when approval is not granted, possibly leading to another State in the Closed category which reflects cancellation of the Work Request. Action: Transition to Completed 15

Example: Activity State Model with Dependencies Activities MAY have dependencies on other Activities being in specific States. Activity-Enabling dependencies and Action-Enabling dependencies are specified as Boolean expressions referred to as Conditions. Activity 1 is not made available to the Assignee until Activity 3 is in “Completed” State. Additionally, while at the “New” Step, Activity 1 won’t be allowed to proceed towards the next Step, “Traveling to Site”, unless Activity 2 is at any Step associated with the State “Ongoing”. 16

Data forms Data Forms are used to model dynamically specified structured information. Data Forms are used, for example, for the purpose of defining Work Request header, overview and instructions, Step level instructions and user input. 18

Work Request Status Record reflects state changes of Work Request after it has been received by the Implementation. An Implementation MUST maintain one Work Request Status Record per each Work Request 22

Reference Data An Implementation MAY provide means for the Manager to establish custom data repositories with arbitrary content “Reference Data” that MAY be used for input value selection, lookup of display values or content validation in Work Requests. An Implementation MAY also provide access to system repositories providing access to selected data on Implementation side, such as Assignee identities and alike. 24

Field-Initiated Request (FIR) is a request initiated by an Assignee and dispatched as a structured message from Implementation to Manager. It is intended for making requests or reporting information outside the usual Activity work flow, such as requesting activation or reset of a specific device, reporting absence of the Assignee, or requesting additional work for the Assignee. 26
