Don’t Blame Bad Software on Developers – Blame it on their Managers

There’s a lot of bad software out there. Unreliable, insecure, unsafe and unusable. It’s become so bad that some people are demanding regulation of software development and licensing software developers as “software engineers” so that they can be held to professional standards, and potentially sued for negligence or malpractice.

Licensing would ensure that everyone who develops software has at least a basic level of knowledge and an acceptable level of competence. But licensing developers won’t ensure good software. Even well-trained, experienced and committed developers can’t always build good software. Because most of the decisions that drive software quality aren’t made by developers – they’re made by somebody else in the organization.

Product managers and Product Owners. Project managers and program managers. Executive sponsors. CIOs and CTOs and VPs of Engineering. The people who decide what’s important to the organization, what gets done and what doesn’t, and who does it – what problems the best people work on, what work gets shipped offshore or outsourced to save costs. The people who do the hiring and firing, who decide how much money is spent on training and tools. The people who decide how people are organized and what processes they follow. And how much time they get to do their work.

Managers – not developers – decide what quality means for the organization. What is good, and what is “good enough”.

Management Mistakes

As a manager, I’ve made a lot of mistakes and bad decisions over my career. Short-changing quality to cut costs. Signing teams up for deadlines that couldn’t be met. Giving marketing control over schedules and priorities, trying to squeeze in more features to make the customer or a marketing executive happy. Overriding developers and testers who told me that the software wouldn’t be ready, that they didn’t have enough time to do things properly. Letting technical debt add up. Insisting that we had to deliver now or never, and that somehow we would make it all right later.

I’ve learned from these mistakes. I think I know what it takes to build good software now. And I try to hold to it. But I keep seeing other managers make the same mistakes. Even at the world’s biggest and most successful technology companies, at organizations like Microsoft and Apple.

These are organizations that control their own destinies. They get to decide what they will build and when they need to deliver it. They have some of the best engineering talent in the world. They have all the good tools that money can buy – and if they need better tools, they just write their own. They’ve been around long enough to know how to do things right, and they have the money and scale to accomplish it.

They should write beautiful software. Software that is a joy to use, and that the rest of us can follow as examples. But they don’t even come close. And it’s not the fault of the engineers.

Microsoft Quality

Problems with software quality at Microsoft are so long-running that “Microsoft Quality” has become a recognized term, for software that is just barely “good enough” to be marginally accepted – and sometimes not even that good.

Even after Microsoft became a dominant, global enterprise vendor, quality has continued to be a problem. A 2014 Computer World article “At Microsoft, quality seems to be job none” complains about serious quality and reliability problems in early versions of Windows 10. But Windows 10 is supposed to represent a sea change for Microsoft under their new CEO, a chance to make up for past mistakes, to do things right. So what’s going wrong?

The culture and legacy of “good enough” software has been in place for so long that Microsoft seems to be trapped, unable to improve even when they have recognized that good enough isn’t good enough anymore. This is a deep-seated organizational and cultural problem. A management problem. Not an engineering problem.

Apple’s Software Quality Problems

Apple sets themselves apart from Microsoft and the rest of the technology field, and charges a premium based on their reputation for design and engineering excellence. But when it comes to software, Apple is no better than anyone else.

From the epic public face plant of Apple Maps, to constant problems in iTunes and the App Store, problems with iOs updates that fail to install, data lost somewhere in the iCloud, serious security vulnerabilities, error messages that make no sense, and baffling inconsistencies and restrictions on usability, Apple’s software too often disappoints in fundamental and embarrassing ways.

And like Microsoft, Apple management seems have lost their way:

I fear that Apple’s leadership doesn’t realize quite how badly and deeply their software flaws have damaged their reputation, because if they realized it, they’d make serious changes that don’t appear to be happening. Instead, the opposite appears to be happening: the pace of rapid updates on multiple product lines seems to be expanding and accelerating.

I suspect the rapid decline of Apple’s software is a sign that marketing is too high a priority at Apple today: having major new releases every year is clearly impossible for the engineering teams to keep up with while maintaining quality. Maybe it’s an engineering problem, but I suspect not — I doubt that any cohesive engineering team could keep up with these demands and maintain significantly higher quality.

Marco Arment, Apple has lost the functional high ground, 2015-01-04

Recent announcements at this year’s WWDC indicate that Apple is taking some extra time to make sure that their software works. More finish, less flash. We’ll have to wait and see whether this is a temporary pause or a sign that management is starting to understand (or remember) how important quality and reliability actually is.

Managers: Stop Making the Same Mistakes

If companies like Microsoft and Apple, with all of their talent and money, can’t build quality software, how are the rest of us supposed to do it? Simple. By not making the same mistakes:

  1. Putting speed-to-market and cost in front of everything else. Pushing people too hard to hit “drop dead dates”. Taking “sprints” literally: going as fast as possible, not giving the team time to do things right or a chance to pause and reflect and improve.We all have to work within deadlines and budgets, but in most business situations there’s room to make intelligent decisions. Agile methods and incremental delivery provide a way out when you can’t negotiate deadlines or cost, and don’t understand or can’t control the scope. If you can’t say no, you can say “not yet”. Prioritize work ruthlessly and make sure that you deliver the important things as early as you can. And because these things are important, make sure that you do them right.
  2. Leaving testing to the end. Which means leaving bug fixing to after the end. Which means delivering late and with too many bugs.Disciplined Agile practices all depend on testing – and fixing – as you code. TDD even forces you to write the tests before the code. Continuous Integration makes sure that the code works every time someone checks in. Which means that there is no reason to let bugs build up.
  3. Not talking to customers, not testing ideas out early. Not learning why they really need the software, how they actually use it, what they love about it, what they hate about it.Deliver incrementally and get feedback. Act on this feedback, and improve the software. Rinse and repeat.
  4. Ignoring fundamental good engineering practices. Pretending that your team doesn’t need to do these things, or can’t afford to do them or don’t have time to do them, even though we’ve known for years that doing things right will help to deliver better software faster.As a Program Manager or Product Owner or a Business Owner you don’t need to be an expert in software engineering. But you can’t make intelligent trade-off decisions without understanding the fundamentals of how the software is built, and how software should be built. There’s a lot of good information out there on how to do software development right. There’s no excuse for not learning it.
  5. Ignoring warning signs.Listen to developers when they tell you that something can’t be done, or shouldn’t be done, or has to be done. Developers are generally too willing to sign on for too much, to reach too far. So when they tell you that they can’t do something, or shouldn’t do something, pay attention.

And when you make mistakes – which you will, learn from them, don’t waste them. When something goes wrong, get the team to review it in a retrospective or run a blameless post mortem to figure out what happened and why, and how you can get better. Learn from audits and pen tests. Take negative feedback from customers seriously. This is important, valuable information. Treat it accordingly.

As a manager, the most important thing you can do is to not set your team up for failure. That’s not asking for too much.

Nice article, If managers and developers design the technical specification document well, then there will be no discrepancies neither from client side nor company’s side.
I emphasis on the TSD every time we start working on a new project.

5. Not knowing enough code themselves, or for larger teams not hiring a dedicated, polyglot code reviewer, who can ensure that each and every component of the system going into the project VCS meets the standards set by the company. Redundant, dead, unrefactored, cut-and-paste, poorly abstracted, globally defined, untyped (or worse, “Any” typed), uncontracted, YAGNI, lacking test coverage code is a disease that slowly rots a project from the inside, especially later as customer requests come in or bugs are reported. Managers who have been out of the coding loop too long or who are unsure of their position as… Read more »

Good article! Inadequate testing is the bane of my life!

I like the post. Having failed a few projects -overrunning in time and budget-, I know that not everything is to blame the software engineer. There’s sometimes lots of politics involved. I’m almost certain that there’s in each project at least one devil’s advocate trying to prove the project wrong -See Mr. Glass’ Dark Side of Software Engineering “”. One part I miss in the post above is how Open Source projects are better with respect to the ones funded for profit mentioned above. One thing is certain, there will always be bugs, according to the TAO of programming 1.4… Read more »

Yes truely said. We cant blame the software engineers for bad softwares rather… mostly its becoz of politics going around and the managers who are handling these projects

Software developers must not be blamed as me to work in a company as a native android app developer. So the software to be created as according to client condition and manager decision. So I think a software developer will work according to their need as they are paying salary.
