Again let me remind you Jeet Kune Do is just a name used, a boat to get one across, and once across it is to be discarded and not to be carried on one’s back

- Bruce Lee, while describing Jeet Kune Do (JKD)

Over the last couple of months, I have been reading a large number of blogs, discussions, arguments, between purists on either side of the “Process fence” as well as middle-of-the-road liberals on what development model is best suited.

There are thousands of successful projects delivered using Agile, CMMI, SPICE, RUP and the hybrids in between, so clearly there is no single silver bullet. That begs the question, is there a single best way to develop software? Increasingly, I feel the answer is No. Even if you decide to go one way due to the needs of the project, it is not necessary to abide by a rigid set of rules prescribed in general by experts in that model.

How then do you decide how to develop software? The answer may lie in adapting JKD’s “The Way of the intercepting fist” philosophy, which, I believe, is closely aligned to Lean “thinking.”

Some thoughts:

• Start with understanding the nature of the project, the clients, the project teams and management needs
• Let this understanding drive the selection of the overall framework. For instance, if the project is to develop against an evolving standard, one of the Agile methods may be suitable. But if the team is not mature in terms of development practices, one of the iterative-but-process-oriented methods like the 2I or RUP may be better
• For engineering practices, use concepts and tools proven within the organization
• For project management, the established way within the organization or PMI’s methodology would be a good start
• Don’t be afraid in discarding practices if they are not useful, but be sure to substitute them with more useful ones. The easiest example I could think of is integration. A big-bang integration is not the norm these days, even in most process-oriented shops, but you can institute multiple daily builds instead of weekly or monthly ones. Another example is using Failure Modes Analysis (FMEA) to drive design decisions in iterations to prevent too much refactoring

There must be a term in psychology to describe this behavior: the moment we associate ourselves with something, we start believing that we must adhere to it 10o%, else the skies will fall on our heads!

As project managers, we must be careful not to fall into this trap, but carry a “toolbox” of practices which can be used in different situations. I am told that successful managers have this toolbox subconsciously, but are unable to spell it out exactly.

What about you? Do you think it is advisable to go with a single system of tried-and-trusted practices or have an assorted toolbox?

Your Process Improvement initiative or even a simple process definition has failed. You have taken the necessary steps to see that you are not defining a stupid process and provided guidance on how to define processes. It still failed, sob. Once you have gotten over it, read on.

The 3 most common ways you can fail at Process improvement, that I have personally seen are:

1. Blind Adherence to Frameworks

Process frameworks such as CMMI or SPICE are intended as guiding principles to help

you develop processes that, in turn, help you achieve your business goals. Trying to incorporate each and every aspect of a framework without regards to its applicability in your organization can result in bloated processes that no one can or will follow.

Usually, process improvement begins with Gap Analysis of existing processes against the chosen Process Framework. This is where you can take a wrong turn.

Understand the intent behind the Framework when performing the Gap Analysis. One tried-and-trusted practice is to extract the objectives from the process (in CMMI, these are neatly defined in the Specific Goals) and then use them to see if the goals are met by your current processes.

2. Committees

Yes, Practitioner-led process improvement is the way to go. But that doesn’t mean that you try to get “representation from every section” of people into your process definition team! After a certain threshold, an increase in the number of people is only going to hold you back.

From my experience, the magic range is 3-5, but that may vary if you are in a business process improvement scenario. One symptom of a dysfunctional large team is endless bickering over every word and its intent when drafting the process – in one case, there was a 2-hour discussion on using “measurements” vs “Metrics”!

3. Endless Alternates

This can be a standalone issue or an offshoot of the first two. I have seen teams debate over different scenarios which they might face, when the probability of these scenarios occurring is really small! Usually, there are a few critical paths where the teams might need direction and then there is a catch-all section (which is usually an escalation path for more guidance).

This situation arises when

• People don’t trust themselves and others to do the right thing and/or
• Managers are not very forgiving when their teams take decisions using judgement and then mistakes happen. Only a learning environment is a growing environment and without it, you cannot help people become mature. Without mature people, you cannot have a high-maturity organization!

Yes, there are more ways in which you may fail, but I’ll follow my own advice and stop from listing out all other scenarios . That, however, does not prevent you from adding your own experiences in the comments. They may be a bigger cause of failure!

Do share in your experiences in process improvement and of course, subscribe to the blog.

In previous posts, we have seen how to use the Six Honest Serving Men to define the elements of a process, while keeping it from becoming stupid. In the latter, one of the items we briefly touched upon was to make Process definition “Practitioner-led.” Today, we’ll dive into this inclusive way a little more.

[In industry jargon, Practitioners are the people who perform the tasks indicated by the process - software development teams, for example.]

Why Practitioners have to participate in process definition? Some common objections encountered are:

• They are not experts in process development
• It is not in their job description or they have other work to do
• If they do it, why do we need process specialists?

While these are valid to some extent, lack of ownership of the very people who have to use the process is the single biggest reason for failure of processes. This isolationist, ivory-tower approach results in processes that are out of touch with reality, do not take into account established practices and a general feeling of “process policing” among the development and project management community.

Most people that I encounter, including die-hard Agile champions, agree that some agreement on how things will be done is necessary when such activities involve many people. A process is such an agreement. When we trust people to develop mission-critical software for us, it is foolish to think that they cannot define an effective way of doing things!

Are you convinced yet? If yes, let us move on and see how we can implement this effective means of defining processes. The title points below are meaningful enough without me trying to elaborate on them.

• Assemble the right team
• Identifying process requirements
• Identifying current practices
• Defining the process
• Piloting
• Implementing

Assembling the right team is probably the most important part of this whole exercise. You need to bring in people of all kinds. You need process champions, critics as well as technical experts.

What about you? You are there to assist them in wording the process, doing the documentation work, creating simple flows and probably to see that process requirements are defined right.

One other thing I have found helpful is to incorporate as many current practices, documents and tools as possible. To do this, you as the process specialist have to talk to people, do the research and generally make it easy for the team to define the process.

A good Practitioner-led process improvement initiative reduces the inertia and encourages others to follow what has been defined by their fellow clan members.

In fact, many guidelines from the SEI show that the use of practitioner-led process improvement journeys lead to sustained improvements in appraisal ratings as well as in achieving project maturity.

In Process – How to develop one that is not stupid, we looked at how we can develop a process that empowers people to do to their thing and not stand in their way. But how do we actually develop one that can assist us in achieving the above goal? Using the concept of Six Honest serving men, we can define a system for activities that involve more than one person. Some of the following content may overlap with other posts, but that’s because they are all related (or maybe I am too dense to write one that explains all).

Why: As I mentioned in a previous post, without stating clearly why we are doing something, it is pretty difficult to convince people to even read something, forget about following it. The Why is often stated in grand terms, and since people are not stupid, they understand it is just for the sake of having it! Have a simple description of the outcome and why following it will help them (in their daily life and not something like, “It will make the organization compliant with the GRAND THEORY OF NOTHING”. Who cares?)

What: What defines the activities that need to be completed to achieve a certain goal. The inputs for this can be based on existing team practices or from best practices in other teams or (God forbid!) from frameworks.

When: When here does not relate to time, but the sequence in which the above activities should be performed.

Who: Code does not get written just because we have defined “Write code”. Someone needs to write it and someone else needs to test it. Mr. Who helps us identify the people to perform the activities in the desired sequence.

Where: This is the easy one. You ask me to enter the bug – fine. Where? You get the idea (please don’t create forms for every small bit of information!  Funny one here – http://www.bureauofcommunication.com/compose/romanticintent)

How: This is the most difficult one. If you list out how to do an activity in great detail, your process will be cumbersome and if you don’t give any details, it will not be useful. Err on the less side, since you can always add detail. This is easy to say, but difficult to implement and unfortunately, the answer for how much is, “It depends, at least for me. By the way, do you have any good principles for this? Share with me.

One of the easiest ways to spell out a process is the System flow chart or activity diagram coupled with annotations for inputs/outputs of the process. This makes the process simple, visual and clear.

If you are wondering if this can be used in Agile methods (not using Agile process, in case you are offended. Ha.), the answer is yes. A process is just a structured method of representing what needs to be done and does not mean it needs to be “heavy”; it can be as light as you need. If you come from a process mature organization and want to find out if you can use Agile methods or not, read this interview and then buy the book (disclaimer: I am not affiliated in any way with the author and have not yet read the book completely).

Go on, become a process specialist. May the Force be with you.

“Process” in the software development world has been characterized with colorful adjectives. I am here to defend it.

What is about the word “Process” that makes people run fro cover? I see a lot of people who turn to Agile, not because they realize its worth, but because they think it frees them to do what they want, how they want. Agile is discipline, folks and you can do it only if you have the maturity to handle that discipline on your own.

Here,  I am defending a process that is simple, provides clear roles and responsibilities, is changed appropriately when needed and most importantly, the one that is applied well. I am not defending a rule book written in circa 1800.

I hear you. You are saying that process as I defined is not the one that you see everyday in countless organizations. Right. But I ask you, is that the fault of the process? Did it slowly creep into your organizations? No, we wrote it. We are the ones implementing it. We are the ones hiding behind it.

A process is nothing but a set of steps we write to accomplish a particular task. We write it down so that others may follow the path easily and when we have thousands of people doing the same task, we don’t want everyone to do it differently, unless circumstances require.

These exceptional circumstances occur more frequently in the SW dev world than in other places like manufacturing (that is why concepts in manufacturing don’t lend themselves well to SW, but that is for another day).

So what do we need? We should define processes that result in desired outcomes. We need to create awareness that a process needs to be adopted and adapted as the situation changes to make it effective. Let us look at some things that we can do to define a process that is not stupid.

1. Define the Why

There is a better chance that people will follow the process if it is clear why and the why is “reasonable”

For example, for software configuration management, the “why” is to ensure that code is checked-in frequently (to avoid crashes or overwrites), follow naming conventions (to easily determine what the file does/belongs by looking at the file name), follow the structure (to modularize code) etc.

2. Minimize Forms

If people have to fill out forms for every step of the process, be sure that will never be followed. While some amount of paperwork is necessary, it should not detract from actually performing the task. The biggest mistake I see people make is trying to get a lot of information filled out, even when that information is not required or may not be used. There are two reasons for this:

• Incorrect interpretation of process frameworks like CMMI or ISO
• When something goes wrong, find out where and why. The failure points are minimal, but to have some documentation for those failure points

3. Practitioner-led

Every activity, whether defined by a process or not, has to be done by someone. Why not ask those people to define the process? It is well-recognized that when a team of practitioners own the process, the adoption is much higher. Do we want someone sitting in an ivory tower to tell me what to do? Nah.

4. Automate

Look for ways to automate as much of the process as possible. If you are capturing information, don’t provide forms for people to capture data. Use tools or write scripts to capture and present that information.

5. Teach people to change it

Make it clear that the process is not sacred. When people start to feel it is not working or not comfortable any longer, change it. Fiercely implement a culture where people can voice their concerns about something that is not working for them.

6. Never talk about the stick

We all know about the “Carrot and Stick”. In this case, however, never ever use the stick. Are we cattle to be driven ahead? Lead us and we’ll follow. What this means is don’t penalize when someone does not follow it. It could be that the process is not usable under stressful situations or the leadership does not care about it. If the manager asks the team to forget about the process just for this urgent request, it shows that the manager does not think the process is useful!

If we follow some of the common-sense principles, any process can be made simple and usable. Otherwise, we will end up defining a complex “Agile” process!

Do you still think Process is stupid? What would you do to help people follow a method that can help them be productive, yet have fun?
