Below are most frequently asked questions from tons of people/SAFe aspirant every month around SAFe SPC CERTIFICATION?
I have good exposure to Agile. In order to boost my career should I go for SAFe SPC certification?
It costs a lot and further $800 to be paid every year to renew it. Is it going to be worth?
How am going to utilize if my company is not on SAFe?
Is it easy?
What’s the process to start teaching? How do I become a trainer?
I am not at all technical and moreover don’t have much exposure to corporate world. What should I do?
Above all, the most important question is
Who is the best trainer? And where should I go and attend the training?
Let me start with the most important and most frequently asked question. You (or your company) re going to spend good amount of money hence you just want to ensure that you truly learn the concepts so that you can leverage. I have personally seen many SPCs struggling to teach because they did clear the exam but didn’t understand the concepts well. People pay the money to be on top in google search doesn’t always mean they are the best. Hence you should do though research before you go for your training. Trust me, the training what you are going to go through has higher weightage than anything else.
I have done good research and I can certainly suggest you the best trainers what I feel would make a difference in your learning based on your location. You can always send an email to me at email@example.com and I will guide you multiple options.
The SAFe exam is not easy as well whilst there are two ways you can crack
Be a smart candidate – Find the right trainer, understand the concepts well and further find a right mentor (Many a times your training org/trainer would play that role)
Be a hardworking candidate – You can’t avoid hard work but not focusing no training and just doing everything by yourself. The disadvantage is you may pass but mostly wont score high. Another limitation is you may lose confidence while teaching people.
I always suggest people to pick the first choice. Your hard-work should be to make your future and not just to clear the exam.
If you are not technical at all and don’t know how corporate world works, then I would say go for Leading SAFe instead of picking SAFe SPC. Or probably you can read details over internet or talk to people those who are SPCs and connected to real world problems solved by SAFe. You may find many institutes would lure you with job success etc but without the basics, it won’t add lots of value.
The majority of companies are building their own SPCs hence don’t expect lots of training requests are coming outside of the market. Although in past two years, SAFe has got lots of traction and probably they are the best when you talk about scaling Agile. If you have good exposure to Agile and feel that you are a good trainer, you can attempt SAFe SPC. The SAFe first principle says “Take an economic view”. I think that’s something you should do it as well.
You should always remember, the principle of product management flow – “While you ignore the economics, it won’t ignore you”.
The exam isn’t easy. In fact, I have seen many people failing the exam despite they scored 80 plus marks in Pre Test. Hence do not take it lightly.
You can always refer my other blog which talks about tips and tricks to score high
In order to start teaching within your company, you should complete respective enablement certifications. For instance you want to teach “Leading SAFe”, you should clear the exam for Leading SAFe post SPC.
The Scale Agile is very good in responding any of the queries hence for any specific questions you can send a message to them and you can expect prompt response. I’m personally a big fan of SAFe since it’s not just processes but it does have lots of leadership, and technology.
Another important point to note is that, if you are a good at technology and at the same time you got a good passion towards Agile, you could be a good trainer. The technology knowledge helps significantly if you truly want to be a trainer. Precisely the chances of success and ROI for doing SPC are quite high.
If your company is not using SAFe and you cant do training outside due to the restriction from your company, you should join SAFe forum and start learning more. With my experience I have seen many SPCs were out of SAFe in this situation due to limited exposure and further who would pay $800 renewal every year.
To be honest, this is just high level. The decision depends on many factors. You can feel free to drop an email along with your number. I would try to help you as much as I can. I am usually available for a call over weekend.
Thanks for reading the blog. Wish you happy and SAFe journey.
The SAFe (scaled agile framework) is getting lots of attention these days. Everyone is going for various certifications based on the role they are playing in the org. People aspire to get good job are opting for SAFe training and certification as well.
I get tons of questions from students, employees, trainers and career aspirants around how do they pass SAFe certification exam and what’s the way to get the maximum value out of it?
I would focus on various SAFe certifications and who should do in my next blog whilst I would focus on “Leading SAFe” or “SAFe Agilist” in this blog.
The Leading SAFe certification should be done by all the leaders and people aspire to play the leadership. I feel SAFe has lots of leadership content in addition to process and practices. I am sure what you learn post Leading SAFe would be must more powerful than many of the Leadership sessions to attend outside market. The leading SAFe focuses on basic building blocks of SAFe and how does leadership support in doing all the right things. Here are some points you must remember
There are no shortcuts hence if you are thinking you would just pass the exam and you would get all the value, forget about it. The real value is in the knowledge you gain hence choose your trainer (SPC) wisely. Don’t go and pick any trainer. Although passing exam is an important activity since that makes you to force yourself and revise all the concepts.
I would advise you to go with a trainer who has good technical background. In the midst for market value, many professional has become SPC certified. I have attended some of the sessions from non-technical trainers and I can tell you, they could not relate a lots of concepts to what we do day to day. Choosing competent, technical trainer is the half battle won. A good coach, and if you know basics of Agile, a 3 days – 6-8 hours study can help you to score 90% plus. It may slightly differ based on how fast or slow learner you are.
Once you are done with coaching, you should study the concepts in 1-2 weeks and go for a practice test. If your score is 85 plus, you can review the deck and go for the exam.
All the students must review the Study PDF received from the SAFe (or Download from SAFe website post enrollment), at least three times. There is another slide which talks about specific links (Chapter Wise), which every student must go through at least twice.
It’s good idea to write down the example given by trainer on each slide which would help you to revise the concepts
Aim to score at least 90 percent, not to show people but ensuring that you truly understood each concept.
You should attempt to do at least 400 to 500 sample quality questions to ensure you understood the concepts and you should be able to go for the exam
Never search questions and answers over internet. A lots of answers are correct on internet and moreover it doesn’t give you a feeling that you are attempting an exam
There is going to be approx. 10% repeat questions from pretest hence do ensure that you got answers for all the pretest questions
I am going to start community of practice on telegram. In case if anyone is willing to join to find

To achieve a goal you have never achieved before you must do things you have never done before ~Stephen Covey
What is so inspiring? All of us already know that in order to do something new, we are expected to do something different.
Well, the answer is “FISH discover water last”. I will write a separate blog to explain why fish discover water last. Lets find out the relation between 4DX and the above quote.
The 4DX or The four disciplines of execution is designed to create a winnable game. Very simple and easy to understand while tricky to implement and sustain because this requires us to work differently than what we do.
Steve Jobs quoted “Ideas are worthless without execution”. It is easy to say that someone “stole your idea” but the truth of the matter is that ideas are worthless until they’re brought to life and executed
The 4 Disciplines of execution – A wonderful book written by Mr. Sean Covey where he talked about how focusing on goals that matter and further how to win the game by step by step process. You can be very well assured that this really works with more than 1500 organizations that have adopted it and seen wonderful results.
In order to understand the disciplines, let’s understand the two key concepts
A leader can influence two of the items when it comes to producing results.
Strategy and Ability to execute that strategy. Which one you think leader struggle with more – I don’t have to ask as it’s obvious.
The answer is the ability to execute the strategy.
In case if you are MBA or spend time in learning management – What did you were taught? “It’s Strategy”
No wonders great strategies fail – Now the question is why people fail to execute the goals – It’s because of whirlwind. Whirlwind – These are existing work and urgent tasks that need attention now. For example – Management reports, KPI, Status report, reviewing code, 1x1s, and the list goes on.
On contrary to that there is another concept called WIG or wildly important goals (WIG) which are nothing but “new activities” and “Innovation” which affects the future success
If you closely observe you would find whirlwind are urgent items because it affects today while WIGs are extremely important items that affect the future. When there is a battle between Urgency and Importance, obviously urgency will win.
Now, let’s understand the 4 step process to make a balance between your WIG and Whirlwind.
Discipline of Focus
Ask yourself if everything else remained the same, what is the one thing you could change that would have the greatest impact.
If you have 4-10 goals – you achieve 1. if you go with more than 10, you typically achieve none. Interestingly if you have 2-3 goals, the chances of achieving them all are very high. Sounds interesting, isn’t it?
To define a WIG; Identify 1. Where are you now, 2. Where you want to be 3. & By When
Or you define the starting line, finish line, and deadline
Focus on your wildly important goals
Focus on less to accomplish more
There are always good ideas than the capacity to execute
Focus on what not how
Inability to reject good ideas
This is the disciplines of focus and the first step for creating a winnable game
Discipline of leverage
The second discipline is to act on the lead measure. In order to understand this, we need to understand lead and lag measures
Lag Measure – Lag measures measure results towards your wildly important goal. They’re easy to measure but hard to influence.
Lead Measures – Most high impact things you must do to achieve your goal.
If we take the same weight loss example, I want to lose 10 kg by December. The 10kg is the lag measure. The lead measure would be cutting 100 calories a day and working our 5 times a week.
Using Lag Measures without Lead Measures is dangerous. They only measure the result of your goal. Lead Measures can influence the chance of success in achieving your goal. They are even predictive of success.
Keep a Compelling Scoreboard
Think of a bunch of players playing a cricket match on the ground
People and teams play differently when they are keeping score, and the right kind of scoreboards motivate the players to win. Great teams know at every moment whether they are winning or losing. They must know, otherwise, they don’t know what they have to do to win the game. We need to publish the score regularly and that should be visible to everyone. The Agile “Information radiators” plays a critical role here.
Discipline 1, 2, and 3 are nothing but a formula for creating a winnable game. Discipline 4 is how we play the game hence it’s the most important activity we need to focus on
Create a Cadence of accountability
Discipline 4 is to create a cadence of accountability – It’s all about regular and frequent team meetings that focus on the wildly important goals. You should remember
This should not last more than 20 to 30 minutes
The meeting should be held at the same time and same day of the week. Consistency is critical to have a sustained cadence of accountability.
The whirlwind never allowed in the WIG session no matter, how urgent it may seem.
The focus of the session is to make team members hold each other accountable. In this meeting, we would have answers to three things
What did we accomplish last week?
Did that move our lead or lag measure or need to course correct
What are 1-2 things we should do to push the lead measure which would push the lag measure?
The Behaviors play a critical role while ensuring 4 steps
Establish a sense of urgency (Kotter’s law of change) – The constant sense of danger to survive or innovative leadership can bring in urgency. Precisely you are expected to challenge the status quo and push employees to no longer be complacent.
Change is inevitable – We need to realize that change is mandatory but you don’t need to be perfect. Have you heard of leaders’ plans to plan and further plan – to achieve perfection but the same focus is not there in execution. Don’t be perfect. Perfection is a fallacy. Start with a good plan and move towards perfection.
Take an economic view – It’s tough to say no to good ideas. Use the Pareto principle which is 20% of ideas will generate 80% of success. Pick what is important and narrow your focus. The human brain is not programmed to multitask. Prioritize looking at the benefits of goal to the organization and not with emotions
Don’t make your Whirlwind to be a WIG – Don’t get so busy that you are 100% reactive. 20% of your time must be focused on doing WIG then only you can make a difference and that would result in organizational success.
The decision should go where the knowledge exists – Unless a decision is one time, makes a significant financial impact, move that to your team. That would help you to move faster and at the same time help your directs to grow in their career.
Intrinsic motivation – This is one of my favorites. This is from the book Drive written in 2009. If you want to bring the highest level of motivation to your team, you should focus on three core factors – Autonomy, Mastery, and Purpose.
Autonomy– people are trusted and encouraged to take ownership of their own work and skill development.
Mastery– people see no limits to their potential and are given the tools they need to continue to improve their skills.
Purpose– people are encouraged to use their skills to achieve a “greater” purpose – for instance, getting involved in a “good cause” that they are passionate about.
Money doesn’t motivate people though not giving enough money demotivates them.
Credit Game – Don’t fall into trap of getting the credit. Have you observed people want to sign up for every initiative just for “Face Value”? As a leader, you should discourage that and moreover lift people up based on the outcome they produce. It is very easy to develop bias because somebody has said great words about your people or your direct has taken up great sessions. Once you are focused on the outcome, people would start getting out of the credit game. Focus on the outcome and not output.
A good leader takes a little more than his share of the blame, a little less than his share of the credit.
Create short term wins – Remember principle #3 – Keeping a compelling scoreboard – It’s imperative to create short term wins. Celebrate your wins – Celebrate success and celebrate failure but ensure that you keep moving towards your goal.
Embrace the feedback – If you are wrong, accept mistakes. If you get feedback, listen, and act. Don’t shoot the messenger instead embrace your messenger. Feedback is the best way to improve faster.
Relentless improvement – Last but not least, continually improve. The relentless improvement is mandatory in the current competing priorities. You can go up the ladder or go down. You can never stay where you are today. Create an environment where people are encouraged to learn, read, and contribute. In fact, go back and read the book which will be given to you. Make sure the team read this before you start following 4 DX in your team.
I want to release anytime, I don’t want iterations, I want to skip estimation, I have challenges with self-organizing teams, I want to change my priorities,
I need better visualization, I want to process that is more adaptable, Scope creep is my major concern, I am want to handle support tickets, I am afraid of sprint failure and end of picking less work, I can’t break down stories enough to complete within the sprint.
Before I get into details, review below carefully, this would suffice the need for moving to Kanban over Scrum or XP.
There are teams that have a more responsive nature of work like maintenance, fixing customer bugs, run time day to day requests, etc.
It may not be a good idea for these teams to plan the sprint or iteration since a lot of activities will become overhead. In addition to that, we need to break the Agile principles for instance constantly adding items to sprint during execution, not doing refinement in advance, accepting back-to-back sprint failure, and more.
Not doing Scrum does not mean they would not publish the work. They are still expected to commit approx work (Preferably in terms of story points) in a given time period.
They commit to goals and SLA based on the past data
Scrum is great while the world is not a perfect place. You can always overcome challenges associated with it but if you have another Agile method is even more flexible there is no harm in leveraging that. I see many organizations are switching to Kanban and getting wonderful results. I don’t have the intention to move you from what you have been doing while I am just trying to initiate a thought process and philosophy around Kanban.
Let’s understand the above in more detail with real-time scenarios. A group of project managers gathered to discuss the challenges they have with the existing process with senior management. Let’s look at some of the interesting areas what they have put forward on the table (I am sure you can relate one or more areas if you have managed agile teams)
Project Manager 1:(Team is afraid of Sprint failure) My team has very fewer items in sprint compare to what they can accomplish as they are scared of sprint failure. Despite that, I don’t have successful sprints as one or items roll most times as we get blocked. I can’t allow my team to pick more middle of a sprint
Project Manager 2: (Prod issues; Lot of support to other teams) My team builds new features while I am expected to support some of the other teams for whom we provide back-end services. The requests coming from them is our top priority whenever it’s related to prod for them. The amount of work that comes from different teams vary and we cannot assign fixed bandwidth to deal with those issues. Most of our Sprint we have one of these two situations
The sprint fails because we need to focus on supporting other teams.
We are done much before the sprint ends. Pulling new work is not allowed mid-sprint hence we use that time for learning while this is not a great idea all the time.
Project Manager 3: (Support work; Tickets) I have all the support work. The estimation has been a challenge most times. A bug takes a day or a week, it all depends on the product I work for is huge and we have most of the newer members. How can I make sure my sprints are successful and at the same time, we as a team don’t under commit?
Project Manager 4: (Adaptive to more adaptive) My team hates too many ceremonies and processes. They think of having a lightweight process which is more adaptive over-prescriptive, is much better. All of them are experienced/committed and understand their roles and responsibilities.
Project Manager 5: (Time and material; Longer stories; Unpredictable work)We built adapters and I don’t see the benefit of breaking down and doing that in parts. We have a deadline for every adapter and we kept getting blocked. We are fine to wait as we are on the “time and material” contract. Getting blocked from the customer end doesn’t harm as billing doesn’t stop. How do I fit in a work which takes a few weeks to a couple of months?
Project Manager 6: (Frequent priority shift) Our priorities changes very frequently. Many times we literally have to stop what we are working on and start something else. Getting new work done in the next sprint doesn’t help as the work we are doing becomes useless even if that’s completed due to change in priority.
Project Manager 7: (Customer or Sprint success) Our company’s top priority is to manage customers and their expectations while we always focus on velocity and sprint success. This becomes challenging as in order to manage customer priorities, we compromise Scrum priorities or vice versa. Both are not good ideas. In the first option, you are disregarding a process resulting in low team morale and an unpredictable outcome. The later is not acceptable anyway 🙂
Project Manager 8: (The product owner struggles)The PO struggles to lock down the requirements for a week. He keeps adding work to sprint throughout the week, changing existing requirements, and even providing/updating acceptance criteria during the sprint.
Projects Manager 9: (Team experience or complex work)My team has challenges with breaking the requirements or estimating the work. The sprint success matters most to me (Why-Sprint-Success-is-Important). I end up being unhappy most times.
Kanban could be one of the solutions for most of the problems listed above. The comparison of Kanban with Scrum/XP and some of the core frameworks is available here
Sprint success is really important when you talk about Scrum. The Sprint fails due to a variety of reasons like team experience, The challenges with breaking down stories, unpredictable work, Customer focus precedes team priorities, support work, and many other challenges as listed above. Many times either we run too much to having a successful sprint (By means of slogging or patch up work) or do not think of a successful sprint at all. Both are not good options.
In my upcoming blogs, I would be talking in detail about how to use Kanban, best practices, myths, and an easy shift from the existing process to Kanban. Please provide your comments below. This would help me to cover all aspects of my next set of blogs on Kanban.
SAFe Agile is extremely prescriptive, works only with command and control from the top management – Is this a Myth? – Let’s explore to know the answer
Before I share my thoughts, let me add a disclaimer
I have a strong faith in SAFe
I am very much inclined to SAFe values, principles, and practices
“If you are on agile, scaling agile becomes relatively easy”
Let’s say your company is running on broken agile processes or is on a waterfall methodology, you can still be successful with SAFe but the chances are reduced significantly. The SAFe suggests significant benefits in 3-5 years while you will hear from people that the magical outcome in productivity, quality, employee morale, etc would come in 3-6 months. Let’s explore slightly deeper:-
I think you would agree that most of the transformations begin with top-down command and control for the simple reason that change is not easy and it needs a real push if it’s not small. This would shift unorganized functions to be more organized, pushes people hard for delivery, teams start running on cadence and synchronization if it’s SAFe resulting in higher productivity, quality and so is the outcome. The KPIs, Metrics, and rigid processes make people do more. There is a forced innovation in the beginning as well. But remember that this would not go long run. The management started believing that we have showcased better outcomes hence let’s not stop. They go with 100 percent utilization which is a disaster (SAFe says so, and I completely agree). The fall begins within 1 or 2 years and it becomes very tough to manage it. The command and control is fine at the start but it should be strictly looked into in six months to a year. The management needs to focus on generative culture, autonomy, and decentralized decision making.
We need to have a relentless improvement in not just the outcome but employee well-being, morale, and learning. We should ensure that we stick to SAFe values and principles. One of the main reasons I have seen for SAFe failure is organizations do not invest much after little success or Org is not ready to move to SAFe but they want to be part of the rat race.
People talk about only success stories while there is a good number of failure stories as well which probably is not taught anywhere. I met many people who ask the interviewer whether the company they are giving an interview is on SAFe or planning to adopt in near future. If the answer is yes to any of these two questions, they don’t want to join the company. There is a myth and perception created while that doesn’t seem to be true. The management truly has to involved at ground level in order to break the myth and move their towards the real benefits of SAFe.
We should all remember that identification of value streams and ARTs, Identification of EPICs are core challenges while implementing SAFe while organization alignment still remains the priority.
I just read an interesting book The ONE Invisible Code – I loved every bit of it. Sharat has done complete justice to convey the message to rise beyond mediocrity.
In this post, I am sharing with you what I found to be interesting in the book. Firstly, this is one of the finest books I read in the recent past. The book is very practical and filled with exercises. This helps you apply the concepts you learn immediately.
The book starts with Joy and his struggles. A failed entrepreneur and an employee. He meets his Mentor in unusual circumstances. The book then picks momentum and is an interesting conversation between Joy and his Mentor. During the conversation, Joy’s mentor helps him get unstuck and makes him realize his full potential.
The book is divided into 4 sections:
Section 1: Orbit of Mastery Vs Orbit Of Mediocrity – Where are you?
Here is where the foundation of every great success is presented in an interesting way. The concept of Orbit Of Mastery and Orbit Of Mediocrity. When we give too much emphasis on safety overgrowth, comfort over the challenge, and short-term pleasure over long-term purpose, we get stuck in the orbit of mediocrity. Mastery begins with self-awareness is something that I really enjoyed.
Section 2: The 4 Mindsets
Knowing and mastering our mindset is the key to achieving all the success and fulfillment. The top priority of every successful individual, entrepreneur, or a corporate leader has been the power of mastering their mindset. When you know your mindset, you can consciously choose to change and sail through any adversity that life throws at you. Learn 4 mindsets and discover your inner potential.
Section 3. Owning The Truth
All high achievers own certain truths which help them create exemplary results. Many of these unconventional truths make you think beyond what you have learned. It’s time to challenge the conventional wisdom and learn to own these truths
Section 4: The ‘ONE’ Invisible Code All high achievers practice a pattern or a series of steps to achieve massive success. Do you want to know what are these steps? Do you want to decode these patterns and find that invisible code? You can discover these steps to breakthrough mediocrity and reach the next level of success in the book.
Both are very similar that are aligned with each other and complement each other. If you walked to a team then it very is very hard to recognize which practice team is using if they are using one of the above practices. XP is Scrum with technical practices. It’s mindset/behavior and a more prescriptive approach with a strong feedback loop.
The iteration is between 2 to 4 weeks.
The iterations are 1-2 weeks or less. For very aggressive teams, it can go up to a day.
In Scrum product owner prioritizes the product backlog but the Scrum team has a privilege to chose a lower priority item in a sprint to work on before the high priority
XP teams must always work in priority order as features to be developed are prioritized by the customer.
Changes in the sprint are not allowed
XP Teams are much more amenable to change within their iterations, but change can only be made if the team hasn’t started working on a feature and at the same time the change is of the equivalent of the swapped item.
The validation of the software is completed almost at the end of each sprint, (i.e. Sprint Review)
The software needs to be validated at all times, to the extent that the tests are written prior to the actual software.
Scrum doesn’t prescribe any engineering practices
The XP does.
The Scrum Master is responsible for what is done in the Sprint, including the code that is written
A developer can modify or refactor the parts of the code as and when the need arises.
The teams start with Scrum and move towards XP. There is lots of focus on Self Organizing teams and XP encourages that to a great extent. The Maturity model that we have prepared for CDK has more focus on Scrum up to level 3 and further, the direction is to adopt XP in order to get on to level 4 and 5.
The original XP is based on four simple values – simplicity, communication, feedback, and courage – and twelve supporting practices as listed below
The Planning Process
The desired features of the software, which are communicated by the customer, are combined with cost estimates provided by the programmers to determine what the most important factors of the software are. This stage is sometimes called the Planning Game.
The software is developed in small stages that are updated frequently, typically every two weeks.
All members on an XP team use common names and descriptions to guide development and communicate on common terms.
The software should include only the code that is necessary to achieve the desired results communicated by the customer at each stage in the process. The emphasis is not on building for future versions of the product.
Testing is done consistently throughout the process. Programmers design the tests first and then write the software to fulfill the requirements of the test. The customer also provides acceptance tests at each stage to ensure the desired results are achieved.
XP programmers improve the design of the software through every stage of development instead of waiting until the end of the development and going back to correct flaws.
All code is written by a pair of programmers working at the same machine.
Every line of code belongs to every programmer working on the project, so there are no issues of proprietary authorship to slow the project down. The code is changed when it needs to be changed without delay.
The XP team integrates and builds the software system multiple times per day to keep all the programmers at the same stage of the development process at once.
The XP team does not work excessive overtime to ensure that the team remains well-rested, alert, and effective.
The XP project is directed by the customer who is available all the time to answer questions, set priorities, and determine the requirements of the project.
The programmers all write code in the same way. This allows them to work in pairs and to share ownership of the code.
