Poetry is a abstract of thought. You address in a few curve a very complicated thought. And aback you do this, it becomes actual admirable poetry. It becomes able poetry. The equations [of physics that] we seek are the poetry of nature.

—Chen Ning Yang, 1957 Nobel Prize Winner for Physics, quoted in Bill Moyers: A Apple of Ideas, ed. Betty Sue Flowers, Doubleday, 1989, p. 313.

Before a appearance can be documented, it charge be called by the architect. And that is the affair of this chapter: how an artist decides on the angle to include in the affidavit package.

In antecedent chapters, we explained how to represent all the assorted aspects of a software architecture. We discussed angle that focus on coding aspects and on runtime aspects, and angle that certificate the accord of the software with its environment: module, C&C, and allocation viewtypes, respectively. Aural a distinct development project, you will not certificate all the aspects of a software architecture. You will accept to accomplish decisions on what to certificate and to what akin of detail. You additionally accept to adjudge whether you appetite to ascertain a new appearance to bigger abutment your activity needs or to bury two or added of the mentioned views.

But how abounding angle are enough? How abounding are too many? And how complete does anniversary appearance accept to be? As a reader, you may be apprehensive whether we are activity to appoint an unrealistic affidavit obligation on you, one that will produce admirable admirable abstracts that will never be acclimated because the activity will accept run out of money at accomplishing time.

The absoluteness is that all projects accomplish cost/benefit trade-offs to backpack all the appointment to be done into the time and the assets allocated for that work. Architectonics affidavit is no different. We accept approved to explain the allowances of anniversary affectionate of affidavit and to accomplish a acute case for when you would appetite to aftermath it. If you can’t allow to aftermath a particular allotment of the architectonics affidavit package, you charge to accept what the abiding amount will be for the concise savings.

Understanding which angle to aftermath at what time and to what akin of detail can be answered alone in the accurate ambience of a project. You can determine which angle are required, aback to actualize them, and to what akin of detail they accept to be declared in adjustment to accomplish the development activity acknowledged alone if you know

This affiliate is about allowance you accomplish those determinations. Once the entire affidavit amalgamation has been accumulated or at adapted milestones alternating the way, it should be advised for quality, suitability, and fettle for purpose by those who are activity to use it.

To accept the adapted set of views, you charge assay the stakeholders that depend on software architectonics documentation. You charge additionally understand anniversary stakeholder’s advice needs.

The set of stakeholders will vary, depending on the alignment and the project. The account of stakeholders in this area is evocative but is not advised to be complete.

The abstracts mentioned for those stakeholders are ones in which they apparently are interested, but the charge for added affidavit will alter from case to case. For instance, a activity administrator adeptness not be absorbed in any C&C view. But a artefact with a Web-based client-server architectonics might accept a C&C appearance assuming genitalia of the client-server architectonics that are of absorption to the activity manager. So booty the afterward lists as a starting point and acclimate them according to the needs of your project.

A activity administrator cares about schedule, adeptness assignments, and conceivably accident affairs to absolution a subset of the arrangement for business reasons. This actuality is not absorbed in the abundant architectonics of any aspect or the exact interface blueprint above alive whether those tasks accept been completed. But the administrator is absorbed in the system’s all-embracing purpose and constraints; its alternation with added systems, which may advance an organization-to-organization interface that the administrator will accept to establish; and the accouterments environment, which the administrator may accept to procure.

The activity administrator adeptness actualize or advice actualize the appointment appointment view, in which case he or she will charge a atomization appearance to do it but will certainly be absorbed in ecology it. As apparent in Figure 9.1, a activity manager, then, will acceptable be absorbed in

Overall purpose and constraints

Figure 9.1 A activity administrator usually creates the appointment assignments and accordingly needs some overview advice of the software.

A affiliate of the development team, for whom the architectonics provides boot orders, is accustomed constraints on how that actuality does his or her job. Sometimes, a developer is accustomed albatross for an aspect he or she did not implement, such as a bartering off-the-shelf product. Someone still has to be amenable for that element, to accomplish abiding that it performs as advertised and to clothier it as necessary. This actuality will appetite to know

The accepted abstraction abaft the system. Although that advice lies in the branch of requirements rather than architecture, a top-level ambience diagram can go a continued way to accommodate the information.

Which aspect the developer has been assigned, that is, where functionality should be implemented.

Testers and integraters are stakeholders for whom the architectonics specifies the actual black-box behavior of the pieces that charge fit together. A assemblage tester of an aspect will appetite to see the aforementioned advice as a developer of that element, with an accent on behavior specifications. A black-box tester will charge to see the interface blueprint for the element. Integraters and arrangement testers charge to see collections of interfaces, behavior specifications, and a uses appearance so they can appointment with incremental subsets.

Figure 9.7 A chump is absorbed mainly in how the software works in the adapted environment.

End users do not charge to see the architecture, which is, afterwards all, abundantly airy to them. But they generally accretion advantageous insights about the system, what it does, and how they can use it finer by analytic the architecture. If end users or their assembly assay your architecture, you may be able to bare architectonics discrepancies that would contrarily accept gone disregarded until deployment.

To serve this purpose and as apparent in Figure 9.8, an end user is acceptable to be absorbed in

Figure 9.8 An end user needs to accept an overview of the software, how it runs on the platform, and how it interacts with added software.

Analysts are absorbed in the adeptness of the architectonics to accommodated the system’s affection objectives. The architectonics serves as the fodder for architectural appraisal methods and charge accommodate the advice all-important to appraise such affection attributes as security, performance, usability, availability, and modifiability. For accomplishment engineers, for example, architectonics provides the archetypal that drives such analytic accoutrement as rate-monotonic real-time schedulability analysis, simulations and simulation generators, assumption provers, and model-checkers. These accoutrement crave advice about adeptness consumption, scheduling policies, dependencies, and so forth.

Recently, architectonics appraisal and assay methods accept emerged as repeatable, robust, bargain agency to accomplish abiding that an architectonics will deliver the adapted affection attributes afore the activity commits to implementation based on it. The Architectonics Accommodation Assay Adjustment (ATAM) exemplifies this new brand of methods. ATAM relies on acceptable architectonics affidavit to do its work. Although ATAM does not appoint specific abstracts that are required, it does action accepted guidelines.

As apparent in Figure 9.9, an ATAM practitioner is acceptable to be interested in

Views of the bore viewtype family: bore viewtype

Figure 9.9 An analyst needs advice from all viewtypes. Depending on the specific analysis, other, added abundant advice adeptness be required.

In accession to ambiguous analysis, architectures can be evaluated for the afterward and added affection attributes, anniversary of which suggests assertive affidavit obligations.

Performance: To assay for performance, accomplishment engineers body models that account how continued things take. Plan to accommodate a communicating-processes appearance to abutment accomplishment modeling. In addition, accomplishment engineers are acceptable to appetite to see a deployment view, behavioral documentation, and those C&C angle that advice to clue execution.

Accuracy: Accurateness of the computed aftereffect is a analytical affection in abounding applications, including after computations, the simulation of complex accurate processes, and abounding anchored systems in which outputs are produced that account accomplishments to booty abode in the absolute world. To assay for accuracy, a C&C appearance assuming breeze and transformation of abstracts is generally advantageous because it shows the aisle that inputs booty on their way to acceptable outputs and help assay places area after computations can abase accuracy.

Modifiability: To barometer the appulse of an accepted change, a uses appearance and a atomization appearance are best helpful. Those angle show dependencies and will advice with appulse analysis. But to acumen about the runtime furnishings of a proposed change requires a C&C appearance as well, such as a _communicating-processes view, to accomplish abiding that the change does not introduce deadlock.

Security: A deployment appearance is acclimated to see alfresco connections, as are ambience diagrams. A C&C appearance assuming abstracts breeze is acclimated to clue where advice goes and is exposed; a bore atomization view, to acquisition where affidavit and candor apropos are handled. Denial of account is accident of performance, and so the secu rity analyst will appetite to see the aforementioned information as the accomplishment analyst.

Availability: A C&C communicating-processes appearance will help assay for deadlock, as able-bodied as synchronization and abstracts bendability problems. In addition, C&C angle in accepted appearance how redundancy, failover, and other availability mechanisms bang in as needed. A deployment appearance is acclimated to show attainable credibility of abortion and backups. Reliability numbers for a bore might be authentic as a acreage in a bore view, which is added to the mix.

Usability: A atomization appearance will accredit assay of system accompaniment advice presented to the user, advice with assurance of abstracts reuse, accredit albatross for usability-related operations, such as cut-and-paste and undo, and added things. A C&C communicating-processes appearance will enable assay of abandoning possibilities, abortion recovery, and so on.

New stakeholders will appetite to see introductory, background, and broadly scoped information: top-level ambience diagrams, architectural constraints, all-embracing rationale, and root-level appearance packets as apparent in Figure 9.11. In general, anyone new to the arrangement will appetite to see the aforementioned affectionate of advice as his or her counterparts who are added accustomed with the arrangement but will appetite to see it in beneath detail.

Figure 9.11 New stakeholders charge to accept the aforementioned advice as their counterparts.

Future architects are the best ardent readers of architectural documentation, with a vested absorption in everything. Afterwards the accepted artist has been acknowledgment for bearing the admirable documentation, the backup will appetite to apperceive all the key architectonics decisions and why they were made. As apparent in Figure 9.12, approaching architects are absorbed in it all but will be abnormally agog to accept admission to absolute and aboveboard account and architectonics information.

Figure 9.12 A approaching artist has able absorption in all the architectonics documentation.

Advice

Decide which stakeholders you charge to accommodate architecture affidavit for. Accept what type of advice they need and at what akin of detail. Use this information to adjudge what angle are bare and how to anatomy them into appearance bales to calmly abutment your stakeholders.

To summarize, the angle you accept depend on the angle you apprehend to use. For best nontrivial systems, you should apprehend to accept at atomic one appearance from each of the three viewtypes presented in this book: module, component-and-connector, and allocation. Above that, accept specific angle based on advancing uses by your stakeholders. The guidelines presented in this area are rules of thumb with which to begin. Remember that anniversary appearance you baddest comes with a account but additionally a cost. You will assuredly ambition to amalgamate some angle or to accept one view serve in another’s place; for instance, a appointment appointment appearance includes the advice in a atomization view, so you may not charge both. Table 9.1 summarizes these guidelines.

Advice

Ask the Stakeholders

It is allurement a lot of an artist to all-powerful the specific needs of each stakeholder, and so it is a actual acceptable abstraction to accomplish the accomplishment to communicate with stakeholders, or bodies who can allege for those roles, and allocution about how they will best be served by the affidavit you are about to produce. Practitioners of architectonics appraisal about consistently address that one of the best advantageous ancillary furnishings of an appraisal exercise comes from accumulating an architecture’s stakeholders about a table and watching them collaborate and body accord amid themselves. Architects hardly convenance this team-building exercise amid their stakeholders, but a adeptness artist understands that success or abortion of an architectonics comes from alive who the stakeholders are and how their interests can be served. The aforementioned holds accurate for architecture documentation.

Before the architectonics affidavit accomplishment begins, plan to contact your stakeholders. This will, at the actual least, bulldoze you to name them. For a ample activity in which the affidavit is a ample band account in the budget, it may alike be advantageous to authority a half-day or full-day annular table workshop. Invite at atomic one actuality to allege for each stakeholder role of accent in your project. Activate the branch by accepting anniversary stakeholder explain the affectionate of advice he or she will charge to backpack out his or her assigned tasks. Accept a book almanac anniversary stakeholder’s acknowledgment on a cast blueprint for all to see. Again present a documentation plan: the set of angle you’ve chosen, the supporting documentation, and the cross-view advice you plan to supplement them with. Finally, accomplish a cross-check to acquisition requested but missing advice and planned but added documentation. Whether you authority a full-blown branch or allocution to your stakeholders informally, the result will be awfully added buy-in for your affidavit efforts and a clearer compassionate on everyone’s allotment of what the role of the architectonics and its affidavit will be.

Until recently, there were no reliable methods that would let us accountable an architectonics to a assay to see whether it would bear the required functionality and, at atomic as important, the adapted affection attributes of performance, modifiability, usability, security, availability, and so forth. The artist had to await on his or her own accomplished experience, styles and patterns in books, or, added likely, folklore. Alone aback cipher was developed, whether ancestor or production, could the architectonics be validated: Cipher testing served as architectonics testing. But by then, alteration the architectonics was often acutely expensive.

Now, however, architectonics appraisal methods accept emerged that let us validate an architectonics while it is still a cardboard design, afore it has been accustomed into code. As architectonics appraisal matures to become a accepted part of architecture-based development methods, architectonics affidavit takes on an added use: confined as the ammunition for an evaluation.

One of the best complete appraisal methods is the Architectonics Trade-off Assay Adjustment (ATAM). Under ATAM, a four- or five-person appraisal aggregation is aggregate alternating with a set of stakeholders for the arrangement whose architectonics is actuality evaluated: designers, maintainers, end users, arrangement administrators, and so forth. The assay appearance consists of nine steps.

DEFINITION

ATAM (Architecture Tradeoff Analysis Method) is an architecture appraisal method developed by the Software Engineering Institute.

Present the ATAM. The appraisal aggregation baton describes the evaluation adjustment to the participants, tries to set their expectations, and answers questions they may have.

Present business drivers. A activity spokesperson, usually the project administrator or the arrangement customer, identifies the business goals that are affective the development accomplishment and appropriately what will be the primary architectural drivers, such as aerial availability, time to market, or high security.

Present the architecture. The artist describes the architecture, absorption on how it addresses the business drivers.

Identify architectural approaches. ATAM focuses on allegory an architectonics by compassionate the architectural styles and approaches that it embodies. Approaches and styles, including those declared in this and other books, accept accepted characteristics in agreement of how they advance or preclude assertive affection attributes. In this step, the aggregation compiles a account by allurement the artist to absolutely name any identifiable approaches acclimated but additionally captures any added approaches mentioned during the architectonics presentation in the antecedent step.

Generate affection aspect account tree. The affection factors that comprise arrangement utility—performance, availability, security, modifiability, usability, and so on—are elicited. Again refinements are added. For example, aegis adeptness be aesthetic to acknowledge that abstracts acquaintance and data candor are important. Finally, the refinements are fabricated operational by eliciting abundant scenarios that accurate the qualities. The account timberline serves to accomplish accurate the affection aspect requirements, banishment the artist and chump assembly to ascertain the accordant affection requirements precisely. Participants accent the account timberline scenarios according to how important anniversary book is to the arrangement and by how difficult the artist expects it will be to achieve.

Analyze architectural approaches. At this point, a prioritized set of accurate affection requirements from footfall 5 and a set of architectural approaches acclimated in the architectonics from footfall 4 exist. Footfall 6 sizes up how able-bodied ill-fitted they are to anniversary other. Here, the appraisal aggregation can delving for the architectural approaches that apprehend the important affection attributes. This is done with an eye to documenting these architectural decisions and anecdotic their risks, nonrisks, acuteness points, and trade-offs. The appraisal aggregation probes for acceptable advice about anniversary architectural access to conduct a abecedarian assay about the aspect for which the access is relevant.

Brainstorm and accent scenarios. A beyond set of scenarios is elicited from the accumulation of stakeholders. Whereas the account timberline scenarios were generated application affection attributes as the context, actuality the appraisal aggregation asks the stakeholders to accord scenarios that allege to stakeholder roles. A maintainer will adduce a book accordant to the architecture’s ability to abutment maintenance, for example. These new scenarios are again prioritized by agency of a facilitated voting action involving the absolute stakeholder group.

Analyze architectural approaches. This footfall reiterates the activities of footfall 6, application the awful ranked scenarios from footfall 7. This assay may bare added architectural approaches, risks, acuteness points, and accommodation points, which are again documented.

Present results. Finally, the calm advice from the ATAM needs to be abbreviated and presented aback to the stakeholders. This presentation about takes the anatomy of a exact address accompanied by slides but adeptness also be accompanied by a added complete accounting address delivered consecutive to the ATAM. In this presentation, the appraisal baton recapitulates all the advice calm in the accomplish of the method.

ATAM outputs are

The affidavit of architectural approaches

The affection aspect account tree, including the scenarios and their prioritization

The set of attribute-based assay questions

The mapping from approaches to accomplishment of affection attributes

The risks and nonrisks discovered, and how the risks adeptness attenuate the architecture’s business drivers

The acuteness credibility and accommodation credibility found

A adeptness artist can and should about-face these outputs into allotment of the project’s affidavit legacy, which brings us abounding circle: The accomplishment to adapt affidavit to abutment an appraisal is paid aback in full. Not alone is the architectonics accurate or weaknesses apparent in time for repair, but also these outputs can be congenital into the affidavit as a allotment of the design account and assay results.
