## Title
Discovering work-item relations through full text and standard method analysis

## Abstract

Discovering work-item relations, in one aspect, may include identifying mappings of work-item elements to standardized specification elements, for instance, by analyzing a plurality of work-item elements and their relationships generated from a description of a collection of work-items, and a plurality of standardized specification elements and their relationships generated from a description of practice guidelines for completing the project. One or more missing relations may be discovered among the plurality of work-item elements based on the mappings.

## Background
FIELD
The present application relates generally to computers, and computer applications, and more particularly to discovering work-item relations.
BACKGROUND
Work-items generically indicate single unit of work which needs to be completed, for instance, in the context of a project. Generally, a project is an undertaking devised to achieve an aim or a goal and includes a plan or scheme involving specific tasks and types of resources. Projects have methods or methodologies, which may define project phases, tasks and workflow, providing specific guidelines or specifications that should be followed in the process of completing a project. Unified framework and Rational® Unified Process are examples which provide such project methods. A project may be associated with a plurality of work-items. For instance, in the context of a software project, work-items include, but are not limited to, the following types of work: design documents, issues, risks, test cases, bugs, and others. In the context of a business transformation project, work-items include, but are not limited to, the following types of work: functional specification, technical specification, reports, interfaces, process definition, strategy, organizational change, and others.
Work-items can be linked according to different link relation types, including, but not limited to: Parent Of, Children Of, Relate to, Blocks, Input From, Output To, Designed In, Tested By, and others to create the basis for project governance and E2E Traceability. In the context of a project, when users create work-items, relations between work-items might not always be expressed because, for example, all team members may not be aware of all activities in team so as to draw the correct relations, also, for example, because many users may miss populating often verbose work-items type and linkages. Not creating accurate relations or links results in unclassified work-item and missing information.
In practical terms, unclassified work-items or missing connections between the work-items may mean increase in project risks, because for example it would be difficult to tell how closely a procedure that should have been followed with respect to a specific work-item was actually followed; slow down in project management, because for instance, multiple reports need to be created and manually re-conciliated through user interaction to have a comprehensive view of the status of the project; slow down in testing, for instance, because work-items may be tested even before their dependent ones are completed; limited efficiency, for instance, because users may be requested to fill in a large number of information for each work-item they create, which could be done automatically if link types or relations have been properly configured; limited comprehension of team working on a project, for instance, because people may not be able to envisage the traceability between different tasks and deliverables stemming from missing work-item types indicating input and output; and poor standardization.
Organizations may establish and/or utilize a standard method or procedure set as practice guidelines for a project. For instance, Rational® Unified Process, Agile Method, Scrum Method are examples of methods used for software engineering projects while Oracle® Unified Method and ASAP (Accelerated SAP®) are methods used in business transformation projects. Each method or procedure defines various tasks, work-products (and optionally other elements such as risks, outcomes) and their possible inter-relationships. Examples of relations may be predecessor—successor dependence between tasks and input-Output work-products from tasks. Standard tools operationalize those methods, and monitor E2E (End to End) traceability.

DETAILED DESCRIPTION
System and methodologies are provided that infer one or more relations between work-items created in a project where such relations are under-specified. In one embodiment, work-items may be mapped to standard method (procedure) elements and relationships may be identified that are defined in the method (procedure) but are missing in the work-item collection.
FIG. 1 illustrates discovering work-item relations through full text and method analysis in one embodiment of the present disclosure. A work-item repository 102 contains work-item and their description. As discussed above, a work-item refers to a unit of work which needs to be completed in the context of a project. For example, in the context of a software project, work-items may include work related to, but are not limited to, design documents, issues, risks, test cases, bugs, and others. As another example, in the context of a business transformation project, work-items may include work related to, but are not limited to, functional specification, technical specification, reports, interfaces, process definition, strategy, organizational change, and others.
A project method 104 refers to a standard specification or procedure that provides guidelines for working on and completing a project, for instance, information about the procedure the project team members are expected to follow when working on a particular project and the deliverables they are expecting to generate.
Full text analysis 106 clusters work-items from the work repository into common categories. Method analysis 108 identifies possible relations among work-item categories, for example, by parsing and extracting information from the project method 104. A project work breakdown structure, as defined by the method, could be automatically created in a work-item-based repository 102 changed over time by one or more users.
Full Text analysis 106 of the work-items and the information obtained from the method analysis 108 (such as teams and project releases) enable discovery of relations between work-item instances. Project Managers 110 may review the process and resolve conflicts, if any. Identified work-item links may be deployed, for instance, updated or stored along with the work-items, for example, in the work-item repository 102.
FIG. 2 is a diagram showing system architecture and methodology in one embodiment of the present disclosure. A parsing component or functionality 210 may include a method parser 208 and a work-item parser 206. The method parser 208 analyzes and parses through a procedural specification (referred to also as method) 204. The procedural specification may be in the form of a free-text, structured context (XML), or others. The method parser 208 generates elements of the procedural specification and links or relationships among those elements. For instance, as a result of the method parsing at 208, a relational graph 212 may be built or formed. For example, a method 204 may be represented as an attribute relational graph 212, W=(VW, EW, AW) with method elements (e.g., tasks, work-products) as nodes and their inter-relationships as edges. In one embodiment, VW defines elements of a method such as, as example, tasks and deliverables. Method elements are usually represented as work-items. EW represents binary relations between method elements (e.g., children of, Related to). Finally, AW defines features, also referred to as attributes, (e.g., title, description, role) of a method element.
The work-item parser 206 analyzes and parses work-items stored in a work-item repository 202, and generates work-item elements and their relationships. For instance, as a result of work-item parsing at 206, a collection of work-items may be represented as an attribute relational graph 214, C=(VC, EC, AC), with work-items as nodes and links between work-items as edges. VC represents work-items or work-item elements. AC is defined similarly as in AW. AC includes attributes of work items. EC defines relationship between work-items, similarly to EW. Although the work-items in C 214 are created to serve the work outlined in W 212, often there is no one-to-one correspondence. There may be similarities between nodes (tasks/work-products) in W 212 and nodes (work-items) in C 214, in terms of their text description, roles, related artifacts, etc. But, links between work-items may be missing. Hence, frequently C does not reflect the same structure as in W. Also, C can have nodes missing in W and vice-versa.
A link discovery module or functionality 216 takes or receives as input the parsed elements of the method 204 and links (or relationships) among them, for example, in a data structure format such as a graph, for example graph W shown at 212. The link discovery module or functionality 216 also takes or receives as input the parsed elements of the work-items from the work-item repository 202 and links (or relationships) among them, for example, in a data structure format such as a graph shown at 214.
The link discovery module or functionality 216 compares the method elements and their relationships to the work-item elements and their relationships and discovers the missing work-item relationships. The output of the link discovery module or functionality 216 in one embodiment of the present disclosure includes an enriched work-item data structure that includes the missing relationships. For instance, a data structure such as a graph, C′=(VC, EC+EI, AC′), where EI is the set of inferred linkages between work-items may be generated. An algorithm for discovering such missing relationship in one embodiment of the present disclosure is described as follows.
A data structure to be output as an enhanced work-item C′ is initialized to input parsed work-item elements and their relationships C, e.g., C′=C.
At 218, the algorithm identifies mappings between pair of nodes in C′ and W such that they are highly similar in terms of their attributes. High similarity is computed by both applying similarity measures to single nodes vi (and its attributes ck) and by looking at pair of nodes vi and vj linked through a relation in EC+EI. In one embodiment of the present disclosure, a node in C′ can be mapped to at-most one node in W; a node in W can have multiple mapped instances in C′. Thus, a work-item element can be mapped to at-most one method element, however, a method element may be mapped to one or more of work-item elements. The similarity may be determined to be “high” if the measure meets a defined threshold or criteria.
Mapping may be performed by one or more similarity comparison methodologies 220, for instance, by string similarity, boolean similarity, and/or relational similarity. String similarity methodology refers to comparing text strings associated with a method element (and its features) and work-item elements (and its features). Different string similarity methodology can be applied, including but not limited to Bonacci distance, Hamming distance and Jaccard Distance. Boolean similarity identifies mapping by making use of partial matching and features weights as in the vector space model. Relational similarity refers to comparing the elements also in context of their neighbors. For instance, if the neighbor of a work-item element is similar to the neighbor of a method element, the work-item element and the method element's similarity measure is strengthened or increased.
At 222, if the mapping creates conflicts, or has low confidence, resolution may be sought from human user (e.g., project manager). Conflicts in mapping may occur, for instance, when the mapping identifies two possible classifications for a single work-item, both with a high level of confidence. A mapping may be determined to have low confidence, for instance, in case the Relational similarity finds a work-item can not be clustered with any similar elements in the neighbor of a method element. In another embodiment, the algorithm may be interactive such that a user may view the mapping and determine manually by inspection, whether the mapping has conflicts or low confidence. At 224, using a user input, any conflict in the mapping may be resolved. The mapping may also be refined with user input.
At 226, edge addition processing is performed. For instance, it is determined whether two nodes in C′ are mapped to two vertices, respectively, of an edge in W. If two nodes in C′ are respectively mapped to two vertices of an edge in W, then an edge between the two nodes in C′ is added, if the edge does not already exist.
The algorithm repeats the above steps 218 to 226 until no new edges can be added, for instance, all edges found in method elements 212 are added to the similar or corresponding work-item elements 214. At 228, an enhanced work-item and mapping data structure is produced, and the work-item repository 202 may be updated with the added relationships.
FIG. 3 is an example of a work-item entry, which may be created or entered via a tool with a user interface screen as shown. As discussed above, software tools exist that track and manage projects based on work-items involved in the projects. An example is Rational Jazz® set of tools from International Business Machines® Corporation, Armonk, N.Y. The Jazz® portfolio includes a common platform and a set of tools that enable all of the members of the extended development team to collaborate. Rational Team ConcertTM, for instance, provides a collaborative work environment for developers, architects and project managers with work item, source control, build management, and iteration planning support. It supports any process and includes agile planning templates for ScrumTM and the Eclipse WayTM. Rational Quality ManagerTM is a web-based test management environment for decision makers and quality professionals. It provides a customizable solution for test planning, workflow control, tracking and reporting capable of quantifying the impact of project decisions on business objectives. Rational Requirements ComposerTM provides a requirements definition solution that includes visual, easy-to-use elicitation and definition capabilities. Requirements ComposerTM enables the capture and refinement of business needs into unambiguous requirements that drive improved quality, speed, and alignment. The tools promote collaboration through the notion of shared work-item.
The example work-item shown is a task involving “developing business logic” as summarized by the title 302. The work-item can include a number of other characterizations associated with it as in the example screen. The entered work-item and the associated information may be stored as text document or another structured document in a work-item repository.
FIG. 4 illustrates a number of link types, thus relationships, a work-item can have with other work-items. FIG. 4 is a screen shot of a software tool that allows users to create work-items and track projects based on the work-items. The software tool enumerates a number of different link types 402 that indicates different relationships a work-item can have with other work-items.
FIG. 5 illustrates an example of a specification or guideline, referred to in this technological art and industry as a “method”, which is usually provided to a project team to follow when working on a specified project. The specification is shown in this example via a tool that allows users to enter or create such specifications. In another embodiment, such specification may be in the form of text documents, web pages, and others. As shown, the specification may include the title of a task involved in a project, in this example, “Develop/Customize store business logic (Commands)” 502. The specification may also indicate one or more relationships 504 this task has with other parts (or tasks) of the project or even possible other projects. The specification may also include a description of the task 506. Other information may be provided in such specifications. The left hand side of the screen shows different tasks, a work-breakdown tree 510, involved in a project, in which the current task 508 is included.
In one aspect of the present disclosure, the methodologies may be used when different projects (or project phases) are merged. For instance, work-items from different projects may be linked according to a methodology of the present disclosure in one embodiment. In another aspect of the present disclosure, the analysis of the standardized method (prescriptive plan, specification or guidelines for practices to follow in working in and completing a project) may be used by method experts to continuously refine the recommended method for future projects. Yet in another aspect, the discovery of relations among work-item elements may facilitate realizing an End to End traceability for the project. Still yet, the discovered relations among work-items may be applied to prevent work-items from being moved to testing before their dependent ones are completed.
FIG. 6 illustrates a schematic of an example computer or processing system that may implement the work-item relations discovery system in one embodiment of the present disclosure. The computer system is only one example of a suitable processing system and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the methodology described herein.
