Customer onboarding

Payments

Loan processing

Mobile banking integration


Project Details

Item Details

Project Type Banking Digital Transformation
Methodology Hybrid Agile + Waterfall
Duration Planned 18 Months
Team Size 45 Resources
Budget $4.5 Million
Technologies Java, APIs, Middleware, Oracle DB
Stakeholders Business, Compliance, Operations, Vendors

What Went Wrong?

1. Unclear Requirements

Business users continuously changed requirements:

Loan workflow changes

AML validation changes

Mobile UI changes


Impact

Frequent rework

Sprint delays

Increased defects

Budget overrun


Root Cause

Requirements were not finalized before development.


---

2. Scope Creep

Initially:

Only retail banking module


Later added:

Corporate banking

SWIFT integration

Fraud monitoring

Regulatory reporting


Impact

Team overloaded

Timeline slipped by 8 months

Additional unplanned cost


Root Cause

Weak change control process.


---

3. Poor Stakeholder Communication

Business teams expected:

Faster delivery

More features


Technical team communicated:

Risks too late

Dependency issues late


Impact

Escalations from client

Loss of trust

Frustration between teams



---

4. Integration Failures

Project depended on:

Core banking

Payment gateway

AML system

Third-party APIs


Many interfaces:

Were undocumented

Had unstable test environments

Failed during SIT/UAT


Impact

Production defects

Delayed testing

High support effort



---

5. Low Test Coverage

Testing started late.

Problems:

No automation testing

Poor regression coverage

Incomplete test cases


Impact

Critical defects in UAT

Multiple production rollbacks



---

6. Resource Utilization Problems

Issues:

Key SMEs allocated part-time

High attrition

New developers lacked banking knowledge


Impact

Productivity reduction

Knowledge gaps

Increased dependency on few senior members



---

7. Unrealistic Timeline

Management committed aggressive deadlines before:

Architecture finalization

Requirement signoff

Capacity planning


Impact

Burnout

Quality compromise

Delivery pressure



---

Final Outcome

Area Result

Timeline Delayed by 10 Months
Budget Increased by 40%
Defects High Severity Production Issues
Client Satisfaction Poor
Revenue Impact Penalties applied
Team Morale Low


The bank eventually:

Reduced project scope

Replanned delivery in phases

Changed vendor governance model



---

Major Lessons Learned

1. Requirement Clarity is Critical

Lesson

Never start large-scale banking development without:

Detailed BRD

Signed-off scope

Acceptance criteria


Improvement

Use:

Workshops

Prototypes

Requirement walkthroughs



---

2. Strong Change Management is Essential

Lesson

Every scope addition must go through:

Impact analysis

Estimation

Budget approval

Timeline revision


Improvement

Implement formal CR process.


---

3. Integration Planning Must Start Early

Lesson

Most banking failures happen at integration stage.

Improvement

Create interface inventory

Validate APIs early

Mock unavailable systems

Conduct integration testing continuously



---

4. Testing Cannot Be Delayed

Lesson

Late testing creates expensive production failures.

Improvement

Introduce:

Shift-left testing

Automation testing

Continuous regression testing



---

5. Stakeholder Communication Must Be Transparent

Lesson

Hiding risks worsens escalation.

Improvement

Maintain:

Weekly governance meetings

RAID logs

Executive dashboards

Clear escalation paths



---

6. Domain Knowledge Matters in Banking

Lesson

Generic developers struggle in banking systems.

Improvement

Train teams on:

Payments

AML

SWIFT

Core banking flows

Regulatory compliance



---

7. Forecasting and Capacity Planning are Important

Lesson

Overcommitment leads to failure.

Improvement

Use:

Velocity tracking

Burn rate analysis

Resource forecasting

Dependency mapping



---

Delivery Manager Perspective

A Delivery Manager should:

Escalate risks early

Protect delivery quality

Control scope creep

Ensure stakeholder alignment

Maintain realistic planning

Monitor budget and utilization continuously



---

Strong Interview Closing Statement

You can explain in interviews:

> “The project failed mainly due to unclear requirements, uncontrolled scope expansion, delayed integration readiness, and weak governance. The biggest learning was that successful banking delivery depends more on proactive stakeholder management, change control, and early risk identification than only technical execution. After the failure, we strengthened governance, improved estimation accuracy, implemented formal change management, and introduced earlier integration and testing cycles.”

Certified Enterprise Architect Professional (CEAP) - Module 5 - Architecture Frameworks

Architecture Frameworks: An Architecture Framework is a theoretical structure that has the purpose of developing, executing, and maintaining an Enterprise Architecture. Advantages of EA framework: Simplify Breaks down areas of the business process Organise business components and create and identify relationships between business Determine the scope Customization in the existing framework Disadvantages of EA framework: Need to follow process Provides only direction and not information It's based on goal and objective Need creativity and proactive thinking Zachman Framework: The Zachman Framework is a widely used model in Enterprise Architecture (EA) that provides a structured way to classify and organize an organization's information infrastructure by defining different perspectives from various stakeholders, allowing for a holistic view of the enterprise and facilitating alignment between business needs and technology solutions; essentially acting as a template to organize arc...

Daily Agile Scrum stand-up meeting guidelines

Followers of the Scrum method of project management will typically start their day with a " stand-up meeting ". In short, this is a quick daily meeting (30 minutes or less) where the participants share the answers to the three questions with each other: • What did I accomplish yesterday?  • What will I do today?  • What obstacles are impeding my progress?  Some people are talkative and tend to wander off into Story Telling .  Some people want to engage in Problem Solving immediately after hearing a problem. Meetings that take too long tend to have low energy and participants not directly related to a long discussion will tend to be distracted. These are the minimum number of questions that satisfy the goals of daily stand-ups. Other topics of discussion (e.g., design discussions, gossip, etc.) should be deferred until after the meeting.  Here are few tips for running a smooth daily meeting:  • Everyone should literally stand-up and no one should sit down ...

Certified Enterprise Architect Professional (CEAP) - Module 4 - Architecture Precursors

 Architecture Precursors: Precursors to modern Enterprise Architecture (EA) include early frameworks like IBM's Business Systems Planning (BSP), which focused on aligning business strategy with information systems, as well as other Information Systems (IS) architecture methodologies that emerged in the 1970s and 80s, emphasizing the connection between business processes and IT systems, laying the groundwork for the holistic view of an organization that EA represents today; the "Master Plan for Information Systems" by Evans and Hague is also considered a foundational concept in this area. Drivers: internal / external pressure enforce to change the system Aims & Directives: Aims:  Goals Objectives Requirements Directives: Principles (example: Principles can be associated with business, data, applications, infrastructure, or security) Policies (example: Members of the public have minimal access to data) Business Rules (example: A rule directs and restricts a procedure)
