Waterfall vs Agile Project Management Models

Waterfall Project Management

When you complete each stage of a project in isolation. You can’t move onto the next stage until the previous one has been completed.

Teams may have frequent meetings in the form of monthly boards, where decisions are made by stakeholders, or dial in meetings with team members who may not work in the same office location (e.g. a Tester who works offshore).

A project example would be upgrades to multiple interlinked computer servers. Server one must first be upgraded first before server two can be looked at.

Pros

  • Methodical and the traditional method of running projects.
  • Works well for projects where there’s one end goal and nothing in between.
  • Enables clear investment decision points and reviews at stage ends and also ensures everything is completed before progressing to the next stage.
  • (Pro or con!) results in stricter levels of governance as projects need to fulfil specific criteria before being allowed to develop and implement.

Cons

  • Slow. A hold up at one stage affects the rest of the chain for the project.
  • This also includes potential impacts on dependant projects who rely on other projects for meeting their deadlines.
  • This in turn can lead to resource inefficiencies, project overspend and failure to meet to time scales.

Instead of aiming to complete whole stages in isolation, Agile projects take a more cyclonic approach, tackling a project delivery in multiple smaller stages (or sprints). Sprints tend to last between two and four weeks.

Teams keep each other informed via stand up Kanban/scrum meetings. An appointed scrum master leads discussions to enable the different teams working on the project provide updates. A) with what they are going to tackle during each sprint (at the start), B) progress updates (during) and C) what they have achieved (at the end). Meetings tend to be more informal and visual compared to Waterfall and the use of whiteboards with post its and/or dedicated software are adopted more frequently to enable updates in a quicker paced project.

Agile Project Methodology

An example of an Agile project would be the development of a App. Over the course of multiple sprints teams are able to gradually build and test the App, first with the basic code, then the functionality, then finally adding in user appeal – pictures, sounds etc.

Pros

  • Fast moving. Enables teams to quickly identify any faults and either fix or ‘drop’ them before too much money and time is invested.
  • Deliveries grow over time, a project leader can start to see formation much earlier into a project, where in Waterfall the change is sudden.
  • Considered to be a more resource efficient model and allows for greater collaboration.

Cons

  • Agile is not a suitable method for all projects. A single delivery can’t be built over time (for example, the delivery outcome ‘running a marathon’ cannot be done in separate sprints. You sign up, train, then run it. An Agile approach would be useless in this instance – you cannot gradually run bits of the marathon over twelve weeks!)
  • The working environment must contain all persons on the project (project lead, governance, software architects, testers, accountants, etc.) to enable collaboration. These resources can only be dedicated to one project or sprint. If resources are split between multiple projects (as they can be on Waterfall) then the sprint may fail to meet its delivery.
  • As sprints are quite short and projects adopting Agile are quicker paced, the project lead must ensure that suitable investment and project governance/review points are put in place as the cycle system doesn’t naturally allow for any sudden or prolonged stops.
  • As it’s a new methodology of project working, team members may require additional support and/or training.

 

 

And there you have it. A (very) quick overview of the two main methods of running projects. I want to add here that I am by no means an expert on either approach, having only started a career in business project management and governance three months ago(!) but hopefully for that reason it will help any new starters in the world get to grips with the basics.

(Also, I hope that doing this will stop Mumma Bennett getting into hysterics when I talk about my job- ‘Waterfall? Ha, ha, haah! What’s Waterfall?! I don’t understand, what’s water got to do with technology upgrades? You’re so corporate!’ and so on and so forth…)

The Perils of Retail Therapy

A memo to the wise; if you do too much of this:

…you’ll end up with an ankle looking like this:

Ok, granted I wasn’t posing in that exact same fashion when my ankle went, but when it started to ache during a shopping trip I decided to ignore the pain and carry on walking on it. I’d decided to venture to the fair Welsh capital of Cardiff and I didn’t want to turn back before I’d even got properly stuck into my needed dose of retail therapy.

As well as the blinking obvious (walking on a duff ankle) there were other things I didn’t fully factor in whilst hobbling around the city centre on a Sunday in mid-late October. These ‘things’ feel into three categories:

  1. The impact of a particularly bad cold virus.
  2. Excitable children on school holidays, pumped up on sugar and in want of Halloween ‘stuff’.
  3. Super eager women, pumped up on caffeine and hell-bent on obtaining Christmas wares before anyone else.

The result was pure shopping chaos, particularly when I became caught up in the shopping centre at peak time. Quickly I found myself bent and morphed into shapes usually reserved only for the most brutal of Twister games. Grunting the pain away like a reindeer on Christmas Eve, I kept my eyes straight and aimed my cold-filled, Rudolf Red, nose towards the nearest exit.

Out of nowhere they came. Turning out of a shop and charging toward me at speed came a group of teenage girls. Dressed in clothes that liberated their pre-pubescent figures, the young women clutched their semi-empty milkshakes in one hand with a firmness that was nearly as strong as their grip on the pre-ripped, bloodied, shirts that were slung over their backs.

“We’ve got the dead look covered this year girls!” One of the party exclaimed triumphantly, as she pored over a small bag of purchased make up. The others nodded in mild agreement, slupping on their milkshakes and scrolling through void blocks of information. At the command of their leader, the group circulated around a black screen to appease the tiny dot before them. The first snap failing to satisfy, they posed for another photo, and another. The look of death had a time and a place, and as far as the camera holder was concerned Snapchat wasn’t one of them.

Upon realising that my collision with the party was both inevitable and likely to write off my foot (for which I felt quite sure the girls lacked any sympathetic insurance), I decided to change my path. Like a Shakespearian character my persona as flipped into a Hellish beast as I gritted my teeth and turned on the sore ankle to walk around the female cluster.

As I hobbled on, dragging my bad leg behind me, I saw bitter sweet irony reflected in the eyes of all the ghoul clad staff who regarded me with confusion and unease. Coffee stands decorated with bloodied bandages and skulls, shops festooned with beaming figurines and tinsel, each environment looked down at me with a soulless attitude that clung onto those who dwelled beneath. Of all the shopper types it was only the husbands and boyfriends that took the crown for being more out of place than I. Loaded like a Biblical Donkey, acting like a Hollywood Zombie, the men of the city took pity and avoided my half dead shape, whilst their respective partners walked in window-display bedazzlement across my path. I gave a half smile of encouragement to these brave men and pressed onwards.

It was a circular pattern of discomfort and disinterest that punctuated the day. The simple pleasures; the reading of a book undisturbed, discovering a nicely styled boot, these glimmers of joy were hard won and so easily lost. A noisy patron in the neighbouring seat, a swollen foot rebelling against a test environment. A reminder perhaps that no one can be a God in the world of the Godless. This thought whispered around my brain in mockery as I slowly staggered towards the bus station. A hissing that ended with the slamming of doors and screeching of the brakes as I departed the capital once again for English soil.

Life, sore ankles and seasonal shoppers; nothing lasts forever.

Facebook: The Importance of Unfriending

I recently did a feature article for The National Student on the notion of Facebook friends and why a clear out of them every so often is nothing but a good thing.

Check out the article here: Facebook: The Importance of Unfriending

What are you thoughts on friends on social media? Do we have too many? Are they damaging or do you see them as harmless numbers?

My Ruddy iPhone 5

I tell you what, I am just about at the point where I could be convinced into throwing my iPhone against a brick wall.

It’s broken down, again.

This is how I felt the first time my series 5 model died on me:

This is how I felt when it black screened on me for the hundredth time about a month ago.

Obama-frustratedjpg.jpg

(But at least back then I was able to revitalise it with my famously soft, gentle, touch *START BUTTON, JAB, JAB, JAB!*)

And this, this is how I feel about the Apple corporation today after my phone completely died on me and failed to even give a damn about starting up.

 

In fact Apple is worse, at least the lady got her cookies from McDonalds in the end. All I got from nagging customer service was the promise of a jiffy bag in the next 3-5 working days for my phone.

Seriously you’d think that in paying so much a month for the privilege of saying to people “I have an iPhone don’t you know?” they could at least produce something that didn’t die after taking one average photo of Cockington (don’t laugh, it’s a real place in Devon, England. The photo would have looked something like this:)

But then my iPhone 5 is now dead so I guess we’ll never know the joys of Cockington manor or Cocktington thatch or my sister sitting on a bench in Cocktington that said “buttocks rest”. We will never know. Hear that? That’s the sound of a my one German fan weeping.

I tell you what, the iPhone 5 is so useless it’s as if Apple have discontinued the model or something…

Is This What Becomes of Love?

Picture a young couple sat on a romantic table for two in the prized window location. Outside, the hum of life acts out its natural course whilst inside the firmly fixed table presents an array of steaming dishes all the colours of the rainbow. But the beautiful pair remain silent. The buzz of life is not as loud as the buzz of technology. Eyes locked on laps the lovers sit in silence, unable to exchange more than a grunt towards each other.

Is this what becomes of love?

Now imagine on the ground below a family. A gathering stood in unity on the very streets which not a week ago cradled their darling as she drifted into a long, deep, sleep. The cracked cement barely clean, the group scroll through comments of condolence and pixelated shouts. The invisible vocals scream for the head of a man they do not know in repayment for a corpse they do not know. Unable to change fate and human emotion, the huddled unit desperately make a plea to the man in the cloud. They beg him to remove their daughter from public memory, but the man says he can’t. What he giveth he cannot taketh away.

Is this what becomes of death?

Take a snapshot of the young woman tottering past the stained tiles in high heels. She joins a group of friends at the town’s third classiest bar on a table laden with overpriced toxic juice. Talk is cheap but photos might equal fame, so they ignore deep conversation in favour of recording every second of this meeting in pictorial form. Every angle in a multitude of colours and effects, it is no wonder that their untouched beverages overflow with melted ice. Who said the world is in a constant state of movement when it can be fixed and recorded in a hundred sepia selfies.

Is this what becomes of life?

Widen the lens and tucked away you find my lone figure in the shadows. The painted ladies momentarily glance in my direction before carrying on as before. Averting my gaze, I shuffle past to an attractive window display at the end of the street, but instead of venturing in I choose to remain external. I photo the object of my desires and walk on before I’m caught in the act. Later I will enable a computer to put another man on the streets from the comfort of my living room sofa. I see you and feel moved to take a secondary snap to share with strangers in Vancouver, Paris and Jerusalem. No model release form needed, I will happily take your pain and use it to claim one second of fame. Anything to get a virtual gratification hit.

Is this what becomes of me?
