When high quality points come up, many Scrum groups look to testing and technical growth practices to deal with the issues. What they usually miss is that poor implementation of Scrum has instantly contributed to their quality issues.
Organizations and groups sometimes tailor Scrum to their particular context. Tailoring can relate, for instance, to the roles, occasions, and artifacts in Scrum. This works effective in case your tailoring nonetheless maintains the integrity of the Scrum framework—for instance, if the aims of the ceremonies are achieved, albeit in a modified method.
However there are many different ways in which efforts to tailor Scrum to your wants can affect software quality. Listed here are the seven ways in which poor Scrum implementation can damage high quality—together with recommendation about how one can keep away from them.
1. Failure to refine your product backlog
A key goal of backlog refinement is to realize a shared understanding of the product backlog gadgets. These are sometimes necessities within the type of person tales. Constructing high quality into the necessities by efficient collaboration in refinement periods prevents defects; it would additionally ship an answer that’s extra prone to be match for goal.
Consumer tales that meet the INVEST criteria are a great observe to make use of in refinement. They show you how to keep away from a typical challenge the place the crew finally ends up specializing in horizontal technical discussions somewhat than priceless (vertical) person tales.
Poor refinement periods and points comparable to partial crew participation signifies that there will not be a shared understanding of the necessities. Utilizing practices comparable to “the three amigos” (referring to a product proprietor, a developer, and a tester) for refinement, however with out subsequent full crew involvement, is one instance of this.
2. Failure to collaborate
Scrum advocates a cross-functional self-organizing development team. Which means code builders and QA/testers should collaborate successfully. With out efficient collaboration, whole-team possession of high quality can be lacking, with apparent implications for software program high quality.
These individuals/cultural behaviors are important parts of efficient Scrum implementation. Some methods to create the specified behaviors embody agreeing on crew values and customary targets—for instance, with a crew constitution—participating in team-building actions, and utilizing collaborative practices.
3. Lack of a devoted product proprietor
The 2020 State of Agile Report said that 36% of respondents lacked enterprise/buyer/product proprietor (PO) availability. With out enough buyer illustration on the crew to assist present high quality necessities after which validate the answer, high quality will endure.
To attenuate this threat to high quality, your crew ought to work on getting essentially the most out of any engagement that it has with a PO. Moreover, it ought to discover collaboration with different stakeholders and subject-matter specialists (SMEs). Examples may embody gross sales/advertising, product administration, regulatory, UX, and so forth.
A crew member may assist drive this collaboration, appearing successfully as a proxy PO and creating the enterprise area experience throughout the crew. Testers are a pure match for this position, given their deal with the exterior high quality of software program.
4. Insufficient definition of completed
The definition of done (DoD) is essential to transparency and consistency of high quality in Scrum. It encapsulates, for instance, your take a look at strategy. This helps be sure that your artifacts (comparable to person tales and increments) are sufficiently “completed.” Points with the DoD occur when the definition:
- Is weak, for instance, if it incorporates imprecise statements comparable to “all assessments passing” with out referencing what sort of assessments or protection targets you will have. Good practices comparable to code critiques, take a look at automation balanced with exploratory testing, code refactoring, and many others. are largely absent.
- Shouldn’t be adopted below stress.
- Shouldn’t be seen as one thing the crew must work on to enhance.
This leads to rapid growth of technical debt, and high quality suffers. Scrum would advocate beginning with no matter good practices you at the moment have however bettering repeatedly (examine and adapt) to work towards reaching “adequate” high quality.
5. Failure to comprehend that Scrum is a pull system
Individuals usually miss this truth. Scrum would not explicitly restrict WIP (work in progress), as Kanban does, to create a pull-based move strategy. As an alternative, contributors implicitly restrict WIP; solely the event crew can resolve what scope is realistically achievable to incorporate within the dash.
Lacking this level leads to an excessive amount of WIP in sprints. This will increase cycle time, causes stress, and demotivates the crew when the dash targets are jeopardized. It usually leads to groups not adhering to the DoD; examples embody inadequate testing, lack of refactoring, and unresolved bugs.
This leads to poor high quality and a rise within the complete price of possession of your software program, due, for instance, to excessive upkeep prices.
Though transferring away from a push system is usually a vital cultural shift for administration, it’s key to rising your stage of agility and delivering high quality software program.
6. Failure to combine your good practices into Scrum occasions
Though chances are you’ll implement the mechanics of Scrum, you additionally want to know the aims and rationale in what you might be doing.
Sprint planning, for instance, entails figuring out which product backlog gadgets (PBIs) you’ll be able to pull into the dash and the way you’ll implement them. “How” means planning the duties you should undertake.
However trotting out the identical commonplace checklist of generic design/code/take a look at duties misses the purpose. The target is for the crew to plan collectively what it must do for these particular person tales/PBIs to satisfy the crew’s DoD.
For instance, addressing quality risk is a basic precept of contemporary testing. Identification and evaluation of high quality threat sometimes occurs informally in agile throughout your conversations. In dash planning, you’ll be able to incorporate this good observe by analyzing high quality dangers for the person tales/PBIs. This helps you outline the take a look at strategy and the related testing duties that the entire crew can use to mitigate high quality dangers.
Replicate in your good practices and the way they will match naturally inside scrum actions.
7. Retrospectives that fail to realize their aims
The entire above Scrum-related points affecting high quality are finally surmountable in the event you maintain inspecting and adapting your means of working. Retrospectives show you how to deal with achieving this continuous improvement.
Sadly, even this aspect of Scrum usually fails to realize its goal. Retrospectives can turn into repetitive, and ultimately the crew might lose its enthusiasm for them. If no actual enchancment actions or experiments come out of retrospectives, it turns into tough to see the profit.
Bringing the actions and experiments into the dash backlog for the following dash emphasizes their significance and supplies the justified visibility. You should utilize them to not focus simply on the Scrum framework itself however on any observe, comparable to testing, that can assist you obtain the required stage of high quality.
Keep away from these high quality points
These seven challenges to profitable Scrum implementation can considerably have an effect on software quality. Growing an understanding of the rationale behind the weather of the Scrum framework will show you how to keep away from these points when tailoring Scrum to your context.
This, mixed with a want to repeatedly enhance, will show you how to reach reaching elevated agility with high quality. Lastly, having somebody in the role of Scrum master is essential to serving to your crew succeed.

He’ll deal with efficient agile testing by following the factors above. He’ll additionally invite contributors to share their very own challenges. The web convention runs November 17-19, 2020.
