[The following template is provided for a Use-Case development, which contains the textual properties of the use case or diagrams.] A single paragraph will usually suffice for this description, however, for more complex use cases, a number of paragraphs may be required. Subject area A use role or other grouping mechanism that can be used to group use cases. Here are some examples of Business Rules: BR1 – Each user is allowed a maximum of 3 logon attempts to the system (configurable) before being locked out. 1. Therefore, when an alternative flow is considered to be significant (i.e. Only identify the available/selectable values for a data item in the flow of events, if the value of the data item is referenced within the use case or if business rules exist in relation to selection of a particular value. Note: Each pre-condition will have a separate sub-section within the use case specification. Are their times during the month or year in which execution of this Use Case peaks? It is quite often the case that a business rule will be applicable to many use cases. Alongside each data item in the list, identify whether it is read only/disabled, and any notes applicable to that data item. TI���`����,��X���8���`^�'��.��s��f����b-�=h�zR�4�.���cB��K?0��������O�� �� PK ! Business rules are chunks of business logic that typically evaluate to a value, most commonly True/False. 112 C HAPTER 7 Next, we need descriptions for the Use Cases. It is so meticulous and why don’t we The precise message text, however, should be stored in a separate artefact, which will be referred to as the Message Catalog. [The following template is provided for a Use-Case Specification, which contains the textual properties of the use case. Within the flow of events, the name of the actor will not be referenced as this is clearly displayed on the use-case diagram, instead ‘The User’ will be referenced. Cockburn presents a diagram (Figure 2.2 in [1]), whose originality and quirkiness are only exceeded by its effectiveness. Each business rule should have a unique identifier (unique within the use case) of the form BRn. A good example of where this approach works well is for messages notifying the user that mandatory information has not been provided. Software Requirements Specification (SRS) Template Items that are intended to stay in as part of your document are in bold; explanatory comments are in italic text. It is more important that the messages presented to the actor are meaningful than to attempt to make messages generic in an attempt to avoid duplication and increase the re-use of messages. “The system displays an error informing the user that the product cannot be supplied on the date requested due to the associated lead time (MSG0001)”. This information should be captured within the flow of events that references the business rule. Is there any predicted increase in the frequency of execution of this Use Case. On selection of the Organisation Element, the System will INVOKE UC11 View Party which will display the details of the selected Organisation Element. One option for managing this is by having a central repository of business rules. The ‘IF’ statement should be a separately numbered, nested step within the Basic Flow (see Nesting sub-section below). That is not to say that it is ok to forget about this section of the use case specification, but more that there is a need to understand the non-functional requirements at a system-wide level and determine which use cases are most pertinent to those requirements. Ideally, this description should take the form of the outline steps involved, however, a paragraph describing the functionality of the alternative flow will suffice if this is not possible. diagram style, unified modeling language, textual format). First Name, Surname, Address Lines 1-4, Post Code, etc. Keep each alternative flow separate to improve clarity. A special requirement may also be a use case specific instance of a system wide requirement that is documented in the supplementary specification. Project Template- Use-Case Storyboard Report For an overview of all the templates available to the requirements work flow see Templates- Requirements . So what is a use case specification? The common flows section is an optional section that should be included within a use case specification when required and will contain a flow for each “collection” of common steps (recommend only using common flows when there are more than 2 contiguous common steps). So what is a use case specification? And if you did, more than likely you will find that the answers to the questions are the same, i.e. A separate business rule should be used for each separate instance of data exchange between an actor and the system to define the mandatory data elements of that interchange. Within certain use case specifications, there may be a number of common steps that occur within more than 1 of the flows. If the Use-Case Specification Document Type is not available in the project's Rational® RequisitePro™ project then this can be created from the supplied Rational® RequisitePro™ Use-Case Specification Document Outline. In reality such questions are best directed to a technical-orientated representative rather than a system end-user. Each Use Case will likely be in a document or file by itself. Any validation that occurs on a data item (e.g. The business will now have been transferred and the user manually produces a letter of confirmation to the IFA which may include the Unearned Commission Liability report.

Note: Each post-condition will have a separate sub-section within the use case specification. 4. In certain circumstances, the flow of events may require a number of steps to be repeated until a certain condition is true, in this circumstance, the FOR EACH…..REPEAT statement should be used e.g. The Unique Identifier of the User Interface should take the form UcnnSCxx.

However, I wonder why should we make a difference between include & extend relationship? People typically adopt a standard use case template for recording the detailed information for the use cases Use Case Template - ATM withdraw case example As mentioned before, there are several notation styles for use cases (e.g. There are specific branches of business use case such as business analyst use case, business specification, business processes and more. Once the “outline” use case has been agreed, the use case will then be elaborated to the full specification, the full specification should include all sections completed. Article includes use case examples, directions for using template to create use cases. Note: A single sentence that does not give much more information than the use case name is not acceptable. Use Case Template for a Restaurant Order System When you place an order as a client, all you have to do is wait for your food to arrive. We follow that with a document template for a Use Case. This is to be achieved by allocating a unique identifier to each user interface with the use case storyboard. Capturing special requirements at a use case level is often viewed as a difficult activity, and rightly so. This prevents the need for breaking the nested steps into an alternative flow. f��ˉ�ao�.b*lI�r�j)�,l0�%��b� Alternative flows should contain a number of steps and may be as long as necessary to describe the events associated with the alternative behaviour. Use Case Analysis. Often this section of the use case specification is overlooked entirely, or conversely people spend all too much effort trying to capture these special requirements for no real gain. The post-conditions may be a textual description of an event or description of information being passed to another use case e.g. The trigger should be documented as the first step within the use case flow of events e.g. The glossary should also be used to maintain the definitions of all business terms used in flow descriptions, this ensures that each term has one agreed definition across all use cases and also helps simplify the use case descriptions. It captures the relationship between the business as a whole and its corresponding customers and partners. Yet gathering complete requirements without exhausting the project schedule and budget remains elusive for many project managers.

use case specification template

This ensures that the flow of events remains fluid and readable and that a set of testable rules are produced that can be applied from more than one point in the flow of events. The use case specification will be based on the activity diagram in Advance – 1 to Total Number of Payments. The following is Derek Coleman’s proposal for a standard use case template (Coleman, 1998), with some minor modifications. Business rules need to be referenced from the flow of events at the point at which that business rule should be applied. Any issues that are outstanding should also be included within the project issues log. USE CASE SPECIFICATION TEMPLATE The next few pages with red text are intended to form the use case template Copy them to a new document for each use case developed for the project. When branching to an alternative flow, the initiating flow should explicitly state the condition why the alternative flow is being invoked (using an ‘IF’ statement). Deze beschrijving is zodanig dat ze een resultaat oplevert dat waarde heeft voor de opdrachtgever / gebruiker. This template also analyzes cases briefly. This paper addresses the complexities of gathering ambiguous requirements, showing how use cases can help so… “The system warns the user that delivery on this date cannot be guaranteed (MSG0002)”. exactly what information needs to be secured? Be aware that this approach to the creation of messages will not work for all types of messages. A use case scenario is a sequence of steps that represents a single use case execution (a scenario is a possible path through a use case specification). ��x � word/_rels/document.xml.rels �(� �U�N�0�#����M��P�^ROHP$�N�I ��[�϶Uݔs�%Ҏ����x=�~�6���9��K@����������%��Dk4�l�M'�g�gh�On! A use case specification captures the requirements, typically of a system, in the form of a use case that contains the descriptive requirements steps in a logical sequence so that document specification can be understood by users to obtain sign-off of their requirements and for testers and developers to understand what is needed by the system to test and build the system functionality detailed in the system use use case. The use case describes what happens inside the system, but not how or why. ut the goal SIMON. List in detail the data items that are displayed on screen or passed between an Actor and the System, e.g. Having a good working knowledge of use cases and how they structured provides a very good basis for understanding and transitioning to using user stories in agile ways or working. By the end of the elaboration phase, approximately 80% of the use cases should have been described to a fully detailed level. When describing nested system processing, nested numbering should be used (e.g. A post-condition of a use case defines the state the system must be in immediately after a use case has finished. Key concepts named in the flow of events should have definitions in the glossary and many of these key concepts will also have related business rules. If you wish to learn further with use cases and use case specifications – Business Analyst Mentor has recommended a list of use case training for business analysts. E.g. Jerry contributed and is acknowledged in the disciplined agile book, Choose Your WoW! The System prompts the user to identify how they wish to allocate the Agent to a Sales Office: The User selects to allocate the Agent to a Sales Office based on geographical region. To ensure that the breadth of the functionality is well understood prior to moving into the detailing of the functional requirements, Use cases will be described at 3-levels depending on the stage of the project: Initially, during the early inception, actors and use cases will be identified, associated, named, given a brief description and an intuitive view of the size/complexity of the use case will be determined. In certain circumstances, a step within the flow may actually have a number of nested steps. Therefore, as a rule, no more than 2 levels of nesting should be used (i.e. A business rule should be used to describe which data items are mandatory. Table 1. People Change | Introduction to the SARAH Model. Business Use-Case Specification: Version <1.0> [Note: The following template is provided for use with the Rational Unified Process. This article provides use case specification guidance gained from working on many projects across a number of different organisations and industry. The System checks the total unearned commission liability. Simple alternatives may be described within the Basic Flow of the use case to describe unusual optional processing or exception processing. Being able to recognise that different use cases do in fact use the same business rule and ensuring that this business rule is worded identically in each use case in which it is used, is difficult in practice. when the Actor is Time or an external system), ‘The Actor’ should be used. ��� N _rels/.rels �(� ���JA���a�}7� Jerry continues to maintain the site to help aspiring and junior business analyst, and tap into the network of experienced, professional business analysts to accelerate the professional development of all business analysts. The flow of events in the use case specification section provides the main bulk of the use case specification and describes what the actor does and what the system does in response. Business rules are not error conditions themselves although they might result in an error condition.i.e. Use Case Specification Document Use Case Specification Template Page 4 of 4 This document was developed for use by programs assigned to the Business and Enterprise Systems Directorate (AFLCMC/HI), and does not To aid understanding and navigation within use cases it can often be useful to include headings within the flow of events describing the action of a group of steps. Each step should be described using standard use case vocabulary (requests, sends, asks, where) and sentence style e.g. the majority of non-functional requirements will be system-wide with a small number specific to a use case. a date between a particular range) or between data items (e.g. There are options available to reduce the amount of duplication of messages by making the messages generic and “parameter driven”. Here is a free Use Case Template from Bridging the Gap that is extremely helpful for business analysts to see an annotated use case specification so you can review them for ideas and compare against any other use case specification template that you may have. Attempt to avoid  “go to step n” statements, however, this may not always be possible. Entered Monthly Insurance Value * Term (in months) = Total insuranceTerm (in months) / (12 / No. Present your case in different levels with the case specification template. We are participants in the following affiliates programs (at not extra cost to you to help with the running costs of this website) for referring any business to these companies: Amazon Services LLC Associates Program, Bridging the Gap, BA Academy, Inc, Adaptive US, Business Analysis Excellence Pty and PassMyInterview. We guide and support them on their personal journeys so that each one of them reaches their full potential in the ever-changing business analysis profession. numeric, date etc), format (e.g. This description should give an overview of the purpose and scope of the use case and clearly define the end goals of the use case. When the final version of the use case specification is issued to the customer, there should be either no outstanding issues relating to the use case or any issues that are outstanding have a documented assumption based on how the project team is planning to progress that has been validated by the client. 4.1. 4.1.1. is acceptable, 4.1.1.1. is not acceptable). Where an error or warning message is reported to an actor, the use case flow of events must state where in the flow of events that the message needs to be reported and provide an indication of what the message is about. Jerry is a member of the following: British Computer Society (MBCS), International Institute of Business Analysis (IIBA), Business Agility Institute and Disciplined Agile Consortium. Use Case Specification Template Download Use Case Specification Template for Free This template includes the following sections: revision, about this document, revision history, 1 description, 2 business purpose, 3 development method, use case specification template, use case specific checks, references. This article provides use case specification guidance gained from working on many projects across a number of different organisations and industry. Each message in the Message Catalog should have a unique identifier of the form MSGnnnn, and the use case flow of events should reference this unique identifier, e.g. This difficulty increases with the size of the business analyst team. A special requirement is typically a non-functional requirement that is specific to a use case, but is not easily or naturally specified in the text of the flow of events. Use Case Specifications Project Phase 2 - Final Team Obiwan Owolabi Legunsen (ool090020) Chris Lindee (cll061000) Kevin Lloyd (kal081000) Radu Matcovschi BenJamin Morin (bmorin) Sam Shaw(sas071100) Kirk Smith However, if it is not appropriate for the use case flow of events to reference ‘The User’ (i.e. Similarly, do not include the flow of events to be triggered if the rule fails validation within the business rule. Therefore, it should be agreed (on the project) that: This process will ensure that the relevant non-functional requirements are captured regarding each use case and the business analyst is suitably knowledgable to explain why the non-functional requirement is pertinent to the use case. The reasons for doing this are to: During the Inception Phase, the use cases will be further described to an outline level of detail, this is important in order to: By the end of the inception phase, all of the use cases should have been described to an outline level of detail. The Agent Earnings System returns the unearned commission liabilities for the Agent Organisation Element. The System prompts the User to enter the Search Criteria (UC10SC01). 4.1.1.). 6�i���D�_���, � ���|u�Z^t٢yǯ;!Y,}{�C��/h> �� PK ! It is phrased in the form of a dialog between the actor and the system. Read what is a use case and how to use it. It is important to look out for business rules that are applicable to more than one use case and ensure the wording of the business rule remains identical across each use case. There are a number of options of tackling this: Each of the above options is not recommended, option A leads to a large maintenance overhead when the common functionality changes, option B makes the case case specification unreadable and also creates an overhead of maintaining the Step No’s, option C will result in a number of very granular use cases. Note: It is recognised that in a large proportion of use cases, the alternative flows usually contain a great deal of the complexity involved within the use case. The “outline” level use-case specification should include the following sections (see later sections in this document for descriptions of the various use-case specification sections): In addition to the above, if any of the other details (business rules, special requirements, issues) have been captured whilst capturing the “outline” level of detail, these should be included within the “outline” use-case specification. Any issues that are encountered whilst elaborating the use case that are significant enough to be discussed outside of the use case workshops, should be documented within the project issues log and a reference to the issue added to this section within the use case. If the flow needs to reference an included use case, embed the activation of the included use case in the flow, stating the name and reference number of the use case. Now that you have a use case model and an overview of the steps inside the use case you are dealing with – next thing to do is to write the use case specification. When an alternative flow ends, the events of the basic flow of events are resumed unless otherwise stated. If it only takes a few steps to describe the alternative processing, do it directly within the Basic Flow of Events section (using an IF statement), rather than using an Alternative Flow. Instead, describe these in the Use case storyboard. it contains some complexity or may involve many steps) it should be described in more detail to ensure that the complexity of the flow is understood as is therefore not under or over estimated. Use Case Specification template Een Use Case (Specification) is de uitgewerkte beschrijving van de interactie van een Actor (menselijk of anders) met het te bouwen systeem. All UML 2.x specifications including UML 2.5 do not mention, define or explain abstract use cases.UML 1.x specification mentioned that "the name of an abstract use case may be shown in italics"but since UML 2.0this sentence was removed from UML specifications without any explanations. The use case description alternative flows section of a use case specification is used to describe either: There may be, and most likely will be, a number of alternative flows in a use case. BR2 – The selected vehicle must be within the maximum and minimum rentals for the Driver’s grade taking into account Driver contribution, (ie. E.g. Use Case Specification: [The following template is provided for a Use-Case development, which contains the textual properties of the use case or diagrams.] A single paragraph will usually suffice for this description, however, for more complex use cases, a number of paragraphs may be required. Subject area A use role or other grouping mechanism that can be used to group use cases. Here are some examples of Business Rules: BR1 – Each user is allowed a maximum of 3 logon attempts to the system (configurable) before being locked out. 1. Therefore, when an alternative flow is considered to be significant (i.e. Only identify the available/selectable values for a data item in the flow of events, if the value of the data item is referenced within the use case or if business rules exist in relation to selection of a particular value. Note: Each pre-condition will have a separate sub-section within the use case specification. Are their times during the month or year in which execution of this Use Case peaks? It is quite often the case that a business rule will be applicable to many use cases. Alongside each data item in the list, identify whether it is read only/disabled, and any notes applicable to that data item. TI���`����,��X���8���`^�'��.��s��f����b-�=h�zR�4�.���cB��K?0��������O�� �� PK ! Business rules are chunks of business logic that typically evaluate to a value, most commonly True/False. 112 C HAPTER 7 Next, we need descriptions for the Use Cases. It is so meticulous and why don’t we The precise message text, however, should be stored in a separate artefact, which will be referred to as the Message Catalog. [The following template is provided for a Use-Case Specification, which contains the textual properties of the use case. Within the flow of events, the name of the actor will not be referenced as this is clearly displayed on the use-case diagram, instead ‘The User’ will be referenced. Cockburn presents a diagram (Figure 2.2 in [1]), whose originality and quirkiness are only exceeded by its effectiveness. Each business rule should have a unique identifier (unique within the use case) of the form BRn. A good example of where this approach works well is for messages notifying the user that mandatory information has not been provided. Software Requirements Specification (SRS) Template Items that are intended to stay in as part of your document are in bold; explanatory comments are in italic text. It is more important that the messages presented to the actor are meaningful than to attempt to make messages generic in an attempt to avoid duplication and increase the re-use of messages. “The system displays an error informing the user that the product cannot be supplied on the date requested due to the associated lead time (MSG0001)”. This information should be captured within the flow of events that references the business rule. Is there any predicted increase in the frequency of execution of this Use Case. On selection of the Organisation Element, the System will INVOKE UC11 View Party which will display the details of the selected Organisation Element. One option for managing this is by having a central repository of business rules. The ‘IF’ statement should be a separately numbered, nested step within the Basic Flow (see Nesting sub-section below). That is not to say that it is ok to forget about this section of the use case specification, but more that there is a need to understand the non-functional requirements at a system-wide level and determine which use cases are most pertinent to those requirements. Ideally, this description should take the form of the outline steps involved, however, a paragraph describing the functionality of the alternative flow will suffice if this is not possible. diagram style, unified modeling language, textual format). First Name, Surname, Address Lines 1-4, Post Code, etc. Keep each alternative flow separate to improve clarity. A special requirement may also be a use case specific instance of a system wide requirement that is documented in the supplementary specification. Project Template- Use-Case Storyboard Report For an overview of all the templates available to the requirements work flow see Templates- Requirements . So what is a use case specification? The common flows section is an optional section that should be included within a use case specification when required and will contain a flow for each “collection” of common steps (recommend only using common flows when there are more than 2 contiguous common steps). So what is a use case specification? And if you did, more than likely you will find that the answers to the questions are the same, i.e. A separate business rule should be used for each separate instance of data exchange between an actor and the system to define the mandatory data elements of that interchange. Within certain use case specifications, there may be a number of common steps that occur within more than 1 of the flows. If the Use-Case Specification Document Type is not available in the project's Rational® RequisitePro™ project then this can be created from the supplied Rational® RequisitePro™ Use-Case Specification Document Outline. In reality such questions are best directed to a technical-orientated representative rather than a system end-user. Each Use Case will likely be in a document or file by itself. Any validation that occurs on a data item (e.g. The business will now have been transferred and the user manually produces a letter of confirmation to the IFA which may include the Unearned Commission Liability report.

Note: Each post-condition will have a separate sub-section within the use case specification. 4. In certain circumstances, the flow of events may require a number of steps to be repeated until a certain condition is true, in this circumstance, the FOR EACH…..REPEAT statement should be used e.g. The Unique Identifier of the User Interface should take the form UcnnSCxx.

However, I wonder why should we make a difference between include & extend relationship? People typically adopt a standard use case template for recording the detailed information for the use cases Use Case Template - ATM withdraw case example As mentioned before, there are several notation styles for use cases (e.g. There are specific branches of business use case such as business analyst use case, business specification, business processes and more. Once the “outline” use case has been agreed, the use case will then be elaborated to the full specification, the full specification should include all sections completed. Article includes use case examples, directions for using template to create use cases. Note: A single sentence that does not give much more information than the use case name is not acceptable. Use Case Template for a Restaurant Order System When you place an order as a client, all you have to do is wait for your food to arrive. We follow that with a document template for a Use Case. This is to be achieved by allocating a unique identifier to each user interface with the use case storyboard. Capturing special requirements at a use case level is often viewed as a difficult activity, and rightly so. This prevents the need for breaking the nested steps into an alternative flow. f��ˉ�ao�.b*lI�r�j)�,l0�%��b� Alternative flows should contain a number of steps and may be as long as necessary to describe the events associated with the alternative behaviour. Use Case Analysis. Often this section of the use case specification is overlooked entirely, or conversely people spend all too much effort trying to capture these special requirements for no real gain. The post-conditions may be a textual description of an event or description of information being passed to another use case e.g. The trigger should be documented as the first step within the use case flow of events e.g. The glossary should also be used to maintain the definitions of all business terms used in flow descriptions, this ensures that each term has one agreed definition across all use cases and also helps simplify the use case descriptions. It captures the relationship between the business as a whole and its corresponding customers and partners. Yet gathering complete requirements without exhausting the project schedule and budget remains elusive for many project managers. Use-case extension is good for re-use (save some time for documenting the use-case specification).

The brief description of the use case specification section should be populated with the brief description of the use case documented. When new technology is added to the mix, the challenges are even greater.
