Why doprojects still fail?

Why projects fail:

Running out of time

Use shortcuts & hacks

Negligence on both sides

You work more than planned

You lose money.

What can you do to keep software

projects from failing?

The standard Project Structure

Evaluate Develop Deploy

The standard Project Structure SUCKS

Not ready

Delay because important infos are missing

Evaluate scope

Not ready „ready“

Important dev-time is already consumed

Unrealistic expectations:

Developers motivation drops.

Problem #1

It doesn't scale

Problem #2

It isn't agile

Problem #1

It doesn't scale

If this happens in a small project you might get away with it.

On a large project it might put your company at risk.

Problem #2

It isn't agile.

Customers need a defned project they

can sell internally to a superior instance

2 Key Processes:

Common Defniton of Scope:

is treated as equivalent to

Specifcations

On Time, On Budget, On Specs

Scope ≠ Specs

On Time, On Budget, On SpecsScope

A project plan based on the

customer's specifcations will fail.

Specifcations refect a feature-list

Scope refects the

production process

≈ Probability of Failure

The probability of a project's failure

increses the more the

anticipated scope fails to match

the de facto scope.

The long list of

underestimated & neglected items

● Don't offer to ft a budget

● Don't offer to ft a time frame

But most important:

Offering

● Don't offer to ft a budget

● Don't offer to ft a time frame

But most important:

Don't lower your offer just to beat the competition

Offering

● Find out who is in charge. The board? Your contact?

● Know the project's priority for your customer and all involved entities?

● Brief 3rd parties. How ft are the other companies involved?

● Be aware of your resources.

● Take into account existing projects.

● Know your escalation paths.

People

● Know your customer's processes

● Think through dependencies What elements are critical?

● Plan time for UX/Prototyping/Design Technical reviews, handovers

● Plan enough time for quality assessment

● PM: In a large project it is a full time job

● Plan enough time for roll-out & closing

Process

● Plan enough time for API negotiaton

● Find out about Environment.

Load Balancing, Master/Slave model

● Plan time for data modelling

● Make a data audit

Technology

● Does the data exist?● What is the form of the data? DB, XML, Excel...● In what state is the data? Normalized? A mess?● How much do you have to build from scratch?● How much to refactor?● How good is the data quality?● What data-synchronisation processes are there?● What is the amount of data in GigaBytes?● Does the planned application cannibalize another?

Data audit

most project disasters are

data related

In my experience

● make projections

● identify risks

● make realistic budget

● make customers realize

- What they need vs. what they want

- What they can pay for

Knowing the scope of a project lets you:

Controlling

Ensuring project objectives are met. Monitoring, correcting and measuring

progress.

Essesntial Tasks

#1 Know your numbers

#2 Keep scope

#3 Enforce deadlines

Know your numbers

● Your budget

● % of budget used

● % of work done

● When will you run out out of budget?

At any time you must know:

What does one hour of develper cost

your company?

Basic costs like

● Wages

● Insurance

● Infrastructure

What does one hour of develper cost

your company?

Basic costs like

● Wages

● Insurance

● Infrastructure

basic costs = loss limit

What is the post calculation rate?

Budget

Hours spentPost calculation rate =

Example 1:

Your basic cost: 100 €

Post calculation rate: 145 €

Proft per hour: 45 €

Example 2:

Your basic cost: 100 €

Post calculation rate: 90 €

loss per hour: -10 €

Keep scope

● Stop and prevent feature creep

● Manage customer expectations

● Channel change requests

Enforce Deadlines

● Make the customer deliver!

● Sprint planning & reviews

● Insist on warranty period

Thank you!
