Micromanagers

Microscope One of the things that we – as workers – hate the most is the micromanager. What is funny is that most people who micromanage others don’t like to be micromanaged themselves. So, why do they do it? Is it effective, despite the backlash? Is it just poor management? Is it a fallback tactic? I can’t claim to have the definitive answers, but here are my thoughts.

Micromanaging is when someone in a supervisory capacity has to know what you’re doing at all times. Often, they may even want to dictate those steps that you take to complete your work. Those two don’t always go together and it is important to realize what you’re dealing with if you’re being micromanaged and what issues you are facing if you’re the micromanager.

I’ll start with the second one first. The supervisor who wants to dictate the steps that you do take to do your work likely does not trust you to do the work properly. I’m not talking about workplaces where you need to follow 95 precise steps to brew Coca-Cola, transport radioactive material, or some other precise job. I’m talking about jobs where you are coding a project, preparing a report, writing a paper, documenting incidents, etc. If someone constantly has to shoulder surf or have updates in order to ensure that you are doing things correctly, then they don’t trust you to do the work.

The other kind of supervisor who has to know what you are doing at all times also doesn’t trust you, but it isn’t because they don’t think you can do your job when you’re doing it. It is because they fear that you’re “slacking off” or “cheating the system”. Their idea of Management™ is to make sure that no one gets paid for 1 minute of time more than they are supposed to and that the department is achieving maximum throughput. Now, having the department run efficiently and with great throughput is good management, but squeezing blood from a turnip is not.

I’m going to deal with the unpopular part of this first. First, you should make sure that you – as the worker – are not a problem. Maybe you’re 100% of the problem, maybe you’re 0.01% of the problem, but a mature person will seek to correct what they can in themselves whenever possible. You know the truth, are you slacking off? Do you do the absolute minimum and take long lunches and stand around and talk every time you can? Do you never communicate status so your manager always has to ask you? If so, you might be the cause of your boss’ behavior. Fix it. If you can’t fix it because you hate your job and this is how you cope? Look for another job. Harsh? Sure, but you’ll be happier if you go somewhere that you want to be and enjoy being.

For those micromanagers who are reading this… your turn. You need to fix yourselves. Even if you do have employees slacking off or doing things incorrectly… you’re not helping. In fact, you’re annoying your employees and running yourself ragged with trying to keep track of their minute-by-minute whereabouts. In second fact, you aren’t really managing anything, you’re babysitting it at best. Who have you grown in a position, mentored up? I don’t mean someone who got promoted entirely on their own merits. I mean someone who was average or below average and you mentored and trained them up into a rising star in the company. If you’re honest, you can probably count that number on one hand or maybe no hands. People don’t rise and thrive under a dictator. However, you possibly have legitimate concerns. Let’s take a look at how you could possibly deal with them in a better way.

Slackers

Maybe people are slacking. Depending on the office culture or your collection of humans, people might be trying to get away with as little as possible. The slacking is on them, but if you micromanage, you’re training people to only work when you’re around and to master the art of looking busy when you aren’t. So, how do you manage your way out of this? This is probably your fault as well. You need to set goals for the results that you want achieved. If you’ve asked for 30 widgets and 30 widgets are getting done, then why are you bearing down on people? On the other hand, if you’ve asked for 30 widgets and only 5 have gotten done, then there is a real issue. At that point, you’ve got to speak to the low performers, coach/train them up, and possibly pursue discipline. Not everyone is a fit with every company.

However, if you’ve asked for 30 widgets and are getting 30 widgets, but you feel like more could be done, then increase the “quota”. If you’ve been measuring all along, you will be able to see if your team is becoming more efficient, less efficient, or stagnating. By being involved at the proper level, you’ll also get a real sense for whether or not your employees are “sandbagging”. But, measuring does not mean demanding or accounting for every second of an employee’s day. People work differently and you need to account for that, but if you’re looking to increase productivity, you’re not doing much more than steadily decreasing your own.

I know that there are people who would bristle at the suggestion that employees aren’t doing their best for the entire day or that there are readers who would believe that I’m advocating for a poor work-life balance. I am a proponent that people should work hard while they are on the clock. If you do that, work-life balance shouldn’t be a problem. If you work hard, taking time off won’t matter because you won’t constantly be behind. If you (and your team) are all doing your best and you’re still behind and there isn’t an obvious point-in-time reason, then you’re understaffed or mismanaged and that’s the manager’s problem. However, I’m not against people who do work more or even work over from time to time to get things done, as I describe in this post from over 9 years ago.

You have to understand, though, that the freedom you are asking for requires that you accept accountability for your work and your work output. It is possible that your department is churning out their 30 widgets, but that is because a handful of people on the team are killing themselves to make it happen. Burning them out so that you can hide in the bathroom and watch TikToks isn’t sustainable and could definitely cause a manager to dig deeper. You will have brought that on yourself.

Any of the environments I’ve described will result in higher than normal turnover, burnout, and lack of innovation. If someone is being dictated to, they’ll never find creative efficiency gains. If a group is being hounded for every second of their time, they’ll never feel safe enough to try and fail some creative new ideas.

Often, though, the consequences of micromanagement are that the manager loses the big picture. The manager’s job is to lead, grow, develop, and put their team in position to be a strategic asset for the company. If the manager is worried about whether Suzy’s bathroom breaks are 5 minutes or less or if Ken starts his knots right-over-left instead of left-over-right, they will not be in the right mindset to think strategically for the mid-to-long term like they should. Honestly, this could be intentional. If the manager was over-promoted and feels more comfortable in their old job, they might easily fall back into habits of dogging the minute-to-minute instead of planning the week-to-week or month-to-month.

So, what do we do about micromanagement? Summing it all up, the TL;DR; is that if you’re a worker being micromanaged, first check your own house. Take a solid look and make sure that you aren’t giving people a good reason to look closer at what you do all day. Once that’s clean, talk to the supervisor or manager. Help them out… manage up. Have the tough talk that you’d prefer not to be micromanaged and see if you can agree to productivity goals and then work hard to meet them. If that goes poorly, deal with it or get a new job.

If you’re in management and someone comes to you, listen. Take an honest look at yourself and see what you can fix or apply. If no one has come to you, but you see yourself in this post, then take a step back. Find some mentors who can give you advice. If you don’t have management mentors, get some. But start with figuring out what productivity that you need and set goals for the department and then step back.

Whether worker or manager, if you work to eliminate micromanagement, stress levels will go down and job satisfaction will go up on both sides of the line.

Survivorship Bias

XKCD Survivorship Bias Cartoon This week, I was listening to a business podcast and the guest was describing the “techniques for success” that they had used and how they now teach those techniques to others. As I began to wonder how much of this (and all such advice) was attributable to Survivorship Bias and planning this post in my mind, I started to think about what image should go with it. Of course there is a relevant XKCD comic, Randall Munroe thinks of everything first.

I’ve been accused of some Survivorship Bias in the past, too. My ideas around how individuals can become successful programmers through individual learning and not through college is how I got started, but am I establishing too much personal credibility on the fact that I made it through a minefield without stepping on a mine? I didn’t give it too much thought until this week.

If you aren’t sure what Survivorship Bias is, the XKCD above does a great job of explaining it. But, the short “word only” explanation is that Survivorship Bias is a kind of selection bias. In this case, the bias places a great deal of attention and credence on things that made it past some gate or obstacle and ignores the less visible things that didn’t make it past.

One example that I used this week is with “Guaranteed Winners for Monday Night Football”. I don’t know how prevalent this is any more, but it used to be advertised everywhere there was sports content. The basic idea is that you call in and they give you the winner of an upcoming football game, ostensibly so you can bet on it and win. The scam is that they give some portion of the callers one team and one portion of the callers the other team.

One of those teams will win and then those callers, bolstered by their win, will call back. The next time, they pay for a “Guaranteed Pick”. Again, the callers are given both teams fairly evenly. This goes on and on until you have people who have won 10 games in a row thinking that this phone line is worth its weight in gold. They might crow loudly about the powers of prognostication that the picker has. The problem is that this entire scenario forgets about the ever-growing portion of callers who have received a losing pick along the way. That’s Survivorship Bias.

So, is all advice bad? Is all advice a by-product of Survivorship?

As in all things, I think the answer is Yes and No.

In my opinion, the way around this is twofold. First, be very wary of a “lone survivor”. If there is only one voice crying out about a path, look for the 90+% who might have followed the same advice to a bad end. Secondly, if people who follow particular advice seem to always improve and you diligently look and you can’t find a significant population of people that failed with the advice, then it is likely good advice.

The problem is that advice can’t be too specific. Now, I believe that through hard work anyone can improve their circumstances. However, what does that even mean? Not everyone starts on a level playing field, with the same advantages or disadvantages, and from the same starting place. You have to know what success looks like for you.

For example: Yes, you are following the email list building advice, but your email list is 1/1000th the size of the person who sold you that course. Consider the advice and consider the circumstances. First, their market is huge. They are selling business products to wannabe entrepreneurs nationwide (or even worldwide). If you are selling backgammon supplies to the greater Sheboygan, Wisconsin area (nothing against Sheboygan), you aren’t going to be able to reach the same number of people.

As for my personal bias about becoming a self-taught programmer, this also has a caveat. You can only do it if you are the kind of person who will dedicate hours to learning and also to practice. You have to be able to learn from just watching videos or reading rather than interaction. You have to create so many side projects and put so much sample code on GitHub. You have to be diligent to study and work even when you get home from your full-time job and your family is fighting for your time. You have to promise to work after people have gone to bed or before they wake up… something. It is hard to know what to do when no one is telling you what to do.

That leads to the other bias secretly at play. There are the concepts of Self-Serving Bias and Attribution Theory. They are related and the relevant part I want to pick out is that people often attribute positive events to their own character but attribute negative events to external factors (Psychology Today). Likewise, if someone else messes up, it is common to ignore external factors and blame the person’s character or drive or something internal to them. We don’t cut them any slack, but we can cut ourselves all kinds of slack.

What can we do? Just be aware. For certain, tell your story. If you see someone successful, listen to their story. Then, in all things, listen critically. Think critically. Take advice generally and apply it to your specific situation where it fits, throw out what doesn’t. If that doesn’t work, try something else. Rapid iteration and prototyping isn’t just for software, it works for approaches to life’s problems and obstacles, too.

Async Void Cannot Access a Disposed Object

A Sink Recently, I was trying to throw a quick method on a controller to create a user on the fly. I was pretty new into a .Net Core Web API project and I just needed to add a quick user to start to test some of the authenticated API calls that I was creating. So, I wrote code that was very similar to this:

[HttpGet("~/peteonsoftware")]
public async void CreateUser()
{
    var user = new ApplicationUser()
    {
        Email = "me@myserver.com",
        UserName = "me@myserver.com"
    };
    var result = await _userManager.CreateAsync(user, "SomePasswordThatIUsed,YouKnowHowItIs...");
}

When I started it up and made a call to http://localhost:56617/peteonsoftware, I got an error that read:

System.ObjectDisposedException occurred
  HResult=0x80131622
  Message=Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.

I could not figure this out. I would debug and stop on the line. My dependency injection was working and my _userManager was populated via dependency injection and I reviewed documentation and what I was calling should work. I lost a lot of time to this. It turns out that I was the victim of some optimization that .Net is doing for me. Notice that my method is async. Notice also that my method returns void. So, as far as .Net is concerned, it can go ahead and return from my method as soon as it fires off that CreateAsync() call because it doesn’t care about the result and it isn’t returning anything anyway.

I naively thought that my await would keep everything holding on until the method returned. NOPE! I found through research that my method was returning before it was done and everything started cleaning up and disposing. Therefore, when the method went to work, everything was disposed, resulting in my error. When I made the small change of no longer returning void, everything worked.

[HttpGet("~/peteonsoftware")]
public async Task CreateUser()
{
    var user = new ApplicationUser()
    {
        Email = "me@myserver.com",
        UserName = "me@myserver.com"
    };
    var result = await _userManager.CreateAsync(user, "SomePasswordThatIUsed,YouKnowHowItIs...");

    // Yes, I know I could just return above, but I like it to be separate sometimes, don't judge me!
    return result;
}

Now when I call, I get back

{"succeeded":true,"errors":[]}

So, lesson to learn… async void is BAD! Lots of unexpected consequences. Always return something from an async method to ensure that nothing gets cleaned up early.

SQL

T-SQL IIF

Decisions Recently, I’ve decided to try to catch up on some things that were “snuck” into SQL Server while I wasn’t paying attention. The first post in this series was about TRY_CONVERT() (which is awesome) and today I want to talk about IIF().

I can’t imagine that there is a single beginner who has written any appreciable amount of SQL queries who at some point didn’t have to Google “how to do an if statement in sql” or ask someone with a little more experience. I certainly know that I had to do that. What you end up with is the CASE statement.

Let’s create a table to work with and populate it with some data.

USE tempdb
GO

IF OBJECT_ID('Customer') IS NULL
BEGIN
	CREATE TABLE dbo.Customer (
		CustomerId INT IDENTITY(1,1) PRIMARY KEY CLUSTERED,
		Name NVARCHAR(100) NOT NULL,
		CreditLimit MONEY NOT NULL,
		Active BIT NOT NULL		
	);

	INSERT dbo.Customer (Name, CreditLimit, Active)
	SELECT 'Nike', 10000000.00, 1
	UNION
	SELECT 'Under Armor', 5000000.00, 1
	UNION
	SELECT 'Reebok', 1000000.00, 1
	UNION
	SELECT 'Buster Brown', 10000.00, 0
END
GO

If we select out all of the data from the table now, it should look like this:

Customer Table Data

So, if we were to run a standard CASE statement against the table, it might look something like this. This statement returns the name of all of the customers along with their “Credit Status”. If a credit limit is greater than 1,000,000, then they are Preferred. Otherwise, they are Standard.

SELECT Name, CASE WHEN CreditLimit > 1000000.00 THEN 'Preferred' ELSE 'Standard' END AS CreditStatus
FROM dbo.Customer

This returns the following results.

Results after CASE Statement

T-SQL finally has an if statement of sorts for use in SELECT statements (logical branching IFs have always existed… I used one in my table create script). Those of you with any kind of VBA background (Access, Excel Macros and Formulas, etc) are probably already familiar with IIF(), which stands for “Immediate IF”. The T-SQL version takes three parameters, just as the VBA version does. The first parameter is the conditional, the second is what will display if the conditional is true, and the third is what will display if the conditional is false. Here is that same Credit Status query rewritten to use IIF().

SELECT Name, IIF(CreditLimit > 1000000.00, 'Preferred', 'Standard') AS CreditStatus
FROM dbo.Customer

You can see that the results are the same and the query does look a little cleaner.

Results after IIF Statement

What if you want to do multiple “layers” of the conditional? Nested IIF statements! Take a look at this query:

SELECT Name, 
IIF(CreditLimit > 5000000.00, 'Platinum', 
	IIF(CreditLimit >= 1000000.00, 'Gold', 'Silver')) AS CreditStatus
FROM dbo.Customer

The equivalent CASE statement would look like this:

SELECT Name, 
CASE 
	WHEN CreditLimit > 5000000.00 THEN 'Platinum'
	WHEN CreditLimit >= 1000000.00 THEN 'Gold'
	ELSE 'Silver'
END AS CreditStatus
FROM dbo.Customer

Both of those return a result set like this:
Nested Conditional Results

So, those statements do the same thing. For complicated conditional logic (especially logic that requires 5 or more decisions), I’d much prefer the CASE statement. Nested IIFs gets pretty dirty once you get that far. However, that appears to be an entirely stylistic choice. If you have any strong preference one way or the other, comment and let me know how you feel and why.
