Software program Documentation, A Worth-Pushed Method
10 min read
The long-term pattern towards Agile mission administration locations an enormous premium on eliminating wasteful overhead. Tasks are transferring sooner than ever, and it’s simple to label documentation as a workflow that produces little worth in comparison with producing extra high quality code.
On this context, software program documentation is usually focused as an exercise that must be in the reduction of. In reality, “working software program over complete documentation” is a key rule for Agile management, and documentation supplies actual long-term worth.
Key Advantages of High quality Software program Documentation
- Expectations keep managed. Rigorously documented mission necessities assist maintain a mission organized, on funds, and on time.
- Wants are addressed. Technical documentation displays the client necessities, requests, wants, and specifics, permitting events to handle arguments.
- A ahead focus is empowering. High quality documentation helps make sure that future improvement work can hit the bottom operating, making certain your software program product is a versatile long-term asset.
- Groups function with cohesion. Good documentation facilitates an optimum handoff from the event staff to these actively managing the appliance (whether or not it’s consumer-facing, B2B, or inner).
- Thorough planning ensures success. Selective, fit-for-purpose documentation preserves the flexibility of Agile improvement whereas making certain adjustments keep tied to a plan that can meet the success of core necessities.
There’s little doubt Agile is pushing away from a inflexible concentrate on exhaustively documenting each function and coding determination. To replicate the dynamism of Agile improvement, fashionable documentation practices have to be adaptable on the fly. The final word want for high quality documentation stays.
On this submit, we break down software program mission documentation and supply some perception into adopting a value-driven method. We begin by figuring out a couple of high-level classes of software program documentation beneath.
Key Features of Mission Documentation
- Necessities
- Structure/Design
- Technical
- Finish-Person
Software program Growth Documentation: Necessities
Properly-documented necessities assist guarantee efficient cooperation and clear communication as builders work to translate enterprise necessities into technical specs.
Necessities ought to clearly outline what must be finished, alongside a exact understanding of what the finished process ought to seem like. A software program necessities doc ought to replicate each useful necessities and non-functional wants (like efficiency and failover capabilities).
In an Agile setting, necessities usually originate as person tales. However the exact technical method for supporting these person tales within the remaining software program product might change over the course of the mission.
A versatile method permits for fast and straightforward implementation adjustments through the product improvement course of. Necessities documentation ought to by no means attempt to restrain this flexibility, solely to verify such fast-paced adjustments are well-tracked.
Mission managers play a key position in making certain that every one stakeholders perceive how altering necessities will have an effect on the general mission. A versatile method is nice, however it might probably’t be allowed to push the app off-course from reaching its central objectives (whereas staying well timed and throughout the funds).
For outsourced improvement groups, the connection between necessities adjustments and mission scope will depend upon the contract employed. If improvement relies on a set scope, requirement adjustments will have to be mirrored within the assertion of labor (SOW). As these adjustments happen and combine into the mission, software program documentation can replicate precisely what perform they serve.
For a time and supplies contract, the mission supervisor can concentrate on the sensible affect of necessities adjustments, saying for example, “We will add this function, however it can require both three further weeks, one further developer, or shelving one other function for this iteration of the product.”

Software program Growth Documentation: Structure/Design
Software program architectural paperwork are used to maintain observe of the highest-level choices made concerning the construction and habits of the system. This documentation must not solely observe necessities, however how options are applied.
Examples of architectural and design documentation embrace the next:
Wireframe Diagrams
These diagrams spotlight your software program’s performance and person interface (UI). By this documentation, you may paint a clearer image of what sort of person expertise (UX) you’re aiming to ship via your software program.
Wireframes are extremely wanted as a consequence of their amalgamation of simplicity and element. Even if you lose any lead builders or groups in your software program, wireframes might help their successors have a agency grasp of your software program’s core construction and objectives.
Person Interface Sketches
Whether or not your software program is B2B or B2C, a point-and-click interface is the life and soul of its performance. A UI sketch refers back to the mock-up of your graphical person interface (GUI) that you just need to create on your finish customers.
By UI sketches in software program documentation, improvement groups can define the preliminary and remaining method to their software program’s GUI. This permits any onboarding builders to know what sort of GUI they are going to be working with, which helps set expectations via visible cues.
Topology Descriptions
Topology descriptions will let you map your software program’s performance and connectivity to different purposes. This additionally permits you to spotlight the accessibility of your software program via a number of units and networks, enabling your improvement staff to supervise your software’s connectivity necessities.
Topology descriptions are useful in any software program improvement method. However they’re significantly important in enterprise software program, the place you need to define your software’s connectivity to different networks in your group. This makes it an essential side to recollect whereas drafting your documentation.
DevOps Info
Agile improvement acquaints your software program with cross-functional and overlapping engineering groups. In contrast, DevOps focuses on implementing collaboration between the event and operational groups. Combining each streamlines software program improvement and supply, staying in step with organizational objectives.
Software program Growth Documentation: Technical
Technical documentation captures program code. Such documentation contains the next:
- API descriptions: useful info for builders to make use of your API, connecting their purposes to your software program.
- Lists of surroundings variables: surroundings variables that tie your software program to sure processes.
- ReadMe recordsdata: software program documentation that helps your builders and end-users be taught extra concerning the functionalities and operations of your software.
It’s no shock that programmers don’t actually like writing documentation and would like to simply create “self-documenting code.” Certainly, numerous automation instruments (e.g., Swagger or Javadoc) enable the era of up-to-date documentation at any given second in time. For fellow programmers, clear and well-structured code actually may have little rationalization.
However whereas high quality code is the inspiration of a profitable documentation technique, even essentially the most pristine code received’t be clear for non-development professionals. Documentation ensures that associated enterprise items have the sources they should assist the software program product obtain its full worth.
It’s additionally value noting that unit checks play an enormous position within the technical documentation course of. To save lots of time, many builders choose to keep away from utilizing them within the face of approaching deadlines. Nonetheless, unit checks will likely be used as code specs, making long-term assist for additional adjustments a lot simpler.
Onboarding is a good instance of the type of sensible operational want that nice technical documentation is instrumental in supporting. High quality documentation ensures that new staff members will want much less hand-holding as they be taught the lay of the land and decrease the probabilities {that a} busy dev staff will neglect to say an important element.
Onboarding may also supply a terrific sensible test on the standard of your present software program documentation. If a brand new staff member evaluations present documentation and appears at midnight about essential features of the mission, there could also be essential gaps to deal with.
Software program Growth Documentation: Finish-Person
Finish-user documentation takes the type of numerous units of directions, person manuals, and tutorials to assist new customers efficiently make use of a software program product.
Trendy apps, net and cellular, don’t usually want a lot end-user documentation. And skillful, intuitive UI design actually minimizes the necessity for formal manuals. However person uptake must be fastidiously thought of as a part of the general improvement course of: even a couple of easy directions can go a great distance. The extra helpful a software program product is to its customers, the extra worth it can generate. In a B2B or consumer-facing setting, some thoughtfully crafted directions might dramatically reduce down on the necessity for stay assist/coaching.
Your end-user documentation doesn’t should be a tedious learn. By creating useful but partaking content material that’s deployed together with your software program, you may make sure that your end-users have all the data they should resolve widespread hurdles on their very own. This provides to their person expertise, whereas serving to you concentrate on the constant refinement of your software program as a substitute of resolving avoidable complaints all by your self.
Following fashionable approaches, you may host this documentation by yourself web site. This cloud-based internet hosting of documentation retains your end-users from being laden with a number of recordsdata when utilizing your software program, whereas additionally permitting you to shortly combine any updates into your software program documentation as they happen.
Software program Growth: Associated Planning
This text is targeted on documentation of the event course of and software program product. Notably, improvement documentation is only one side of the planning that goes into maximizing the worth of a software program product.
Offering for the whole lot, from advertising and marketing to post-launch assist and product technique, is crucial to a software program product’s final success.
For a deeper have a look at how cautious planning might help de-risk software program improvement, we suggest our weblog right here.
The Worth of Match-for-Objective Documentation
There’s no onerous science to mission documentation, and practices must be stored versatile sufficient to be tailor-made to the mission at hand: fit-for-purpose documentation will keep away from each extraneous documentation work and the type of poorly documented work that proves expensive.
Typically, the bigger and extra advanced a software program product is, the extra documentation it can require. Even in an Agile world, an enormous enterprise app with plenty of advanced integrations and secondary performance might require substantial documentation. Equally, a simple net app might solely want an ultra-lean documentation method.
On the subject of managing documentation through the mission itself, staff dimension is one other essential variable.
For a smaller staff that’s incessantly speaking a couple of mission, check-ins over a platform like Slack could be the solely course of wanted to maintain staff members knowledgeable of related documentation adjustments. By way of instruments, a smaller firm constructing a comparatively easy app might merely observe initiatives in a Phrase doc or SharePoint.
For a bigger staff, or a staff working for a bigger enterprise with extra in depth inner reporting processes, a extra formalized method to software program documentation adjustments and staff communication could also be obligatory.
Distillery’s Cautious However Sensible Method to Documentation
At Distillery, for instance, we use Jira-based mission administration and have expertise with instruments like Confluence (a wiki-based documentation software with full Jira integration). Whereas these instruments could make constructing and sharing documentation as simple and clear as doable, they’re certainly not essential to constructing high quality documentation — we additionally efficiently ship initiatives for purchasers who make use of a a lot less complicated method to documentation.
Regardless of the instruments employed, it’s the mission supervisor’s duty to trace how every staff member is documenting their a part of the mission, making certain satisfactory data is being recorded.
At Distillery, our objective is at all times to provide the quantity of documentation wanted to facilitate mission objectives, no roughly. We make use of checklists, for example, to make sure that satisfactory documentation is produced throughout all areas of the mission.
For any given space, like DevOps or structure, the quantity of documentation required by the mission at hand might actually be very restricted. Total, the objective isn’t to create demonstratively “complete” documentation, however to keep away from arbitrary decision-making: extreme and insufficient documentation each have actual prices.
We’ve seen either side of this price danger up shut. In some circumstances, we’ve been engaged in initiatives the place in depth documentation necessities took a number of weeks of devoted time from a developer. We’ve additionally been referred to as in to work on apps that different distributors left inadequately documented; it might probably take substantial quantities of time to know the construction of the software program and its surroundings, even when the code is high quality.
When Distillery arms off a accomplished mission to a consumer after a profitable improvement cycle, we sometimes conduct a handover name to go over all accomplished and excellent duties. This preliminary data switch is a good time to reply questions and resolve any remaining points. Software program documentation, in the meantime, helps make sure that this information is institutionalized: preserved for the long run and paired with all the sensible sources wanted for future improvement work.
Studying Extra
We hope this text supplies a helpful framework for serious about documentation for a improvement world more and more outlined by lean, Agile considering.
Nice documentation is only one piece of the very best practices that go into constructing nice, customized software program merchandise. For those who’d wish to be taught extra about Distillery’s method, get in contact with us right here.
