A Road Trip and Guidelines on Agile Estimating and Planning

While reading the book Agile Estimating and Planning by Mike Cohn,  i came across a chapter on Dozen guidelines for Agile estimating and planning. The book  and guidelines reminded me of a road trip that myself and two friends undertook from Delhi to Leh and back, in 2011.

What follows is an account of what we planned to do and what we ended up doing actually and more importantly, how our preparation followed the guidelines of agile estimating and planning, albeit unknowingly.

What was planned
Trip Duration was 9 days. Plan was to travel from Delhi to Manali to Leh, via Keylong and Sarchu. Spend time in Leh, see Pangong Tso lake, visit khardung la , one of the highest motorable passes in the world and few monasteries around Leh. Return route was Leh-Kargil-Srinagar-Pathankot - Delhi. The attached map shows the route planned ( courtesy google maps)


Day 0 - Arrive in Delhi - Hire cab
Day 1 - drive via manali rohtang pass  (rohtang means pile of corpses) and at Night - Rest in Keylong

Day 2 - Drive Past Sarchu and take rest in plains - if possible reach leh
Day 3 - See around Leh
Day 4 - See around Leh
Day 5 - See around Leh
Day 6 - See around Leh
Day 7 - Start return trip back to Delhi
Day 8 - Drive to Delhi
Day 9 - Reach Delhi and catch evening flight back home


What was considered in planning. Planning started as soon as we were forced to abort a similar trip in 2010

• Timing was key. Depending on snow fall, the Manali  Leh Road opens anytime from May-June. It may also get closed in case of heavy snow fall. When open, priority is always given to Army Vehicles.
• If we took the trip too early, we risked not completing the trip due to snow blocked roads. If we did the trip in August, the snow capped mountains will have less snow and the view will not be that great.
• Be in good physical condition. The terrain and altitude can be demanding. so regular exercise was part of the preparation 
• Experiences from an aborted trip in 2010 when we couldn't proceed beyond Keylong.
• Bad roads and unpredictable weather leading to traffic jams
• High altitude sickness (HAS): Altitude sickness is a serious health concern. If not attended to in time, it could turn out to be fatal. (HAS and preparation against it deserves a separate post)
• Time delays caused by stopping to Photograph on the way as accommodated.

What Actually Happened

Day 0 - Arrive in Delhi - Hire a cab - Start driving at early hours of day 1

What caused the road block

Day 1 - Afternoon - Reached Manali Skipped lunch to  drive beyond Manali. But Traffic Jam caused by bad road stopped us. We waited in queue as we thought, would get through - but couldn't - As it was too late to return to manali, we decided to stay in a tent and have food at a roadside dhabha.

Day 2 -   Traffic was still blocked at day 2 morning. We decided to come back to Manali and take  rest. 2 of the 3 show signs of food poisoning.

Day 3 - Start at 3.30 Am to cross Rohtang pass. We manage to cross the blocked road. But our innova was gashed by a heavy vehicle that slipped. In the process,  Innova loses LHS rear view mirror and suffers damage. The LHS front door couldn't be opened from outside. Crossing the breached road gave us some jittery moments as a mistake in driving the vehicle could lead to a disconnected clutch. Due to the skills of the person who was driving, we crossed this place safely.  We stopped for lunch along the way and decided to drive as long as the lights would allow and ended up staying in Sarchu for the night .

Our damaged vehicle

A word about Sarchu. Sarchu- altitude is 4290 metres. Though the travel guides suggest that people take an over night break at Sarchu, i wouldn't advise it as HAS is never far off. It was cold, we were tired and food went cold in the time it travelled from the plate to our mouth. Two of the team of three were completely down and couldnt sleep well.

Day 4 - Morning while trying to have breakfast (we didn't feel like eating anything), checked at the tent for the nearest army hospital. We visited the hospital that was a few thousand metres away. The doctor checked us and  two of the three put on oxygen. Fortunately for us, the oxygen levels improved and with some suggestion and advice along with free medication,  doctor  says the team is fit to drive. Tells us that we will be okay once we reach Leh and asks us to consult a doctor there.

Sarchu - Road condition 

    The reason why  i mentioned about improving oxygen levels is that for a fellow traveller, who was riding a motorcycle, oxygen levels didnt improve even after being on orxgen. He was advised to reach lower altitudes as soon as possible, lest it could turn out fatal.

Day 8: Drass - it was freezing and we stopped over for a cup of tea

Day 5 - Afternoon Reach  Leh . Team still unwell. As suggested by the army doctor, we decide to acclimatize by taking complete rest  for the day.  Consult with a doctor in the evening and he told us that the food poisoning aggravated the HAS as the bacteria that caused the food poisoning consumed some of the already depleted oxygen.

Day 6 - See around Leh - Visited Thiksey and Hemis Monasteries.

Day 7 - Start drive back to Delhi. Visit Alchi Monastery on the way. Overnight stop at Kargil

Day 8 -  Early morning start from Kargil. Route back was Kargil- Drass - Srinagar-Pathankot and Delhi.

Day 9 - Almost non stop drive for 36 hours - reach Delhi just in time to catch evening flight back home

Lessons Learnt

• It was a physically demanding and tiring journey, but mentally very fulfilling. In physically demanding trips, if people are not set in the right frame of mind, it will only make the trip more difficult and intolerable...So the team composition becomes very important - Lesson learned from 2010 trip
• The roads demanded complete focus on driving and drivers always had to be at their best.

  

  Demanding Roads

• Don't skip food at any point. Whenever wherever possible, have a heavy breakfast. Fat in the form of butter is fine as the body needs it a lot.
• Don't stay at Sarchu overnight - The altitude makes things bad and complicates it for people who are not very fit.
• Keep drinking lot of water when in Leh. Water mixed with electrol is better. Dehydration is a serious problem
• Our plan was too aggressive and we should plan for a 15 day trip and not a 9 day trip to cover in detail all that we planned.
  
• Don't drive when tired and avoid night driving as much as possible
• The picturesque views along the way were worth the trip and more. What is captured through photos is only miniscule part of it and doesn't do justice to the place.
• When body suffers from low haemoglobin levels, it impairs the ability to absorb oxygen. While this is okay at plains, it is not at all okay at higher altitudes. One of the ways to improve haemoglobin levels is regular exercise.
• The Army hospitals are equipped with the best of infrastructure and open only when the roads are open ( may to september/october).  
• The roads are maintained by Border Road Organization (BRO) who man the roads round the clock. We owe the successful completion of the trip to the Indian Army and BRO.

I  think we followed certain Guidelines for Planning, when i look back at the trip now after two years.

• Like Agile Projects, we were time boxed. We had set out to achieve certain objectives ( drive by road from Delhi to Leh and back to Delhi) and to see places in and around Leh, but were constrained by the fact that we had 9 days to achieve this objective.
• The whole group understood the objectives of the trip, the perils involved  and was involved in decision making, though primary responsibility for certain activities fell with one person.
• Planning happened at different levels ; at the highest level it was the road trip and it was gradually broken down with the lowest being the immediate destination on hand.
• The distance to be travelled and the total time needed were never mixed. 
• Uncertainty in our plan was accepted and expressed using range. time taken to reach a place was always expressed x hours plus or minus y hours and never x hours. depending on the actual time made, subsequent targets were accordingly modified.
• Planning happened on the ground and kept changing often.
• Lessons learnt on the ground were continuously incorporated into subsequent planning. 
• What could be achieved in a day was kept realistic and not over ambitious - other than the drive to reach delhi because we had to be at work next day .
• What we could see/accomplish was continuously prioritized - we dropped Pangong Tso and Khardungla as the group wasn't physically upto the demands and were worried about HAS.
• Planning happened based on actual numbers and also on our experience from 2010 trip.
• We did leave some slack in the planning, but that slack was consumed by the delay in crossing Rohtang pass

Bill Watterson's Advice on Life and Creative Integrity

Calvin and Hobbes is one of my favorite comic strips. I never tire reading it and  usually end up laughing out loud or with a chuckle.  My respect for Bill Watterson, the creator of Calvin and Hobbes went up a lot when i found that he refused to allow his creation for merchandizing.

I recently came upon a post in brainpickings.org titled "Advice on Life and Creative Integrity from Calvin and Hobbes Creator Bill Watterson". 

While i liked the whole post, the following quote stood out and resonated a lot with me.


"Creating a life that reflects your values and satisfies your soul is a rare achievement. In a culture that relentlessly promotes avarice and excess as the good life, a person happy doing his own work is usually considered an eccentric, if not a subversive. Ambition is only understood if it’s to rise to the top of some imaginary ladder of success. Someone who takes an undemanding job because it affords him the time to pursue other interests and activities is considered a flake. A person who abandons a career in order to stay home and raise children is considered not to be living up to his potential—as if a job title and salary are the sole measure of human worth.

You’ll be told in a hundred ways, some subtle and some not, to keep climbing, and never be satisfied with where you are, who you are, and what you’re doing. There are a million ways to sell yourself out, and I guarantee you’ll hear about them.

To invent your own life’s meaning is not easy, but it’s still allowed, and I think you’ll be happier for the trouble."

Exercises in Style - An Interesting Read.

On a crowded bus at mid day, the narrator observes one man, accusing of another of deliberately jostling him. The man then occupies an empty seat.The narrator observes him again in another part of the town when the man is advised by a friend in having an additional button to his overcoat.

The book 'Exercises in Style' by Raymond Queneau, retells the above 'unremarkable' story in 99 different ways. Each style or mode is less than a page and occasionally runs into two pages.  the whole book is 121 pages.


The interesting part is not the story as such, but the realization on how the language used changes the story from one mode into to another and gives it a different feel.

The book is fascinating, funny, very creative and kindles your imagination.  And this was originally written in French and i read the translated version.

I would suggest reading one or two story at a time and relishing it. And i leave it to you to decide that, but would strongly recommend this book.

Seven Rules of Management

I read the following Rules in the book "Brain Rules". For a change, these seven rules of management are from a toddler's perspective.


If I want it, it is mine. 
If I give it to you and change my mind later, it is mine.
If I can take it from you, it is mine.
If we are building something together, all of the pieces are mine.
If it looks just like mine, it is mine.
If it is mine, it will never belong to anybody else, no matter what.
If it is yours, it is mine.


I am sure these will bring a smile to anyone who has seen a baby growing up, from close quarters. The not so funny part is that you will come across adults trying to enforce these rules in real life or when working together in projects. working with them is one of the more interesting parts of project management. :-)

Wordle takes the words from any web site one enters and turns them into a "cloud" of mixed up words reflecting the contents of the web site home page.

The resulting aggregation may look mixed up, but i believe it strongly reflects the content of this blog.
